Description

  The present invention relates to a technology for managing and providing information related to power distribution such as customer contract information and distribution system information, and performing a demand response when power supply is tight, for example, a power information management system.

  In the supply and demand of electric power, it is necessary that the amount of demand power (hereinafter referred to as demand amount) and the amount of supplied power (hereinafter referred to as supply amount) match. Therefore, when the demand amount increases, the power amount is increased accordingly. However, if the demand is asymptotic to the maximum supply or expected to exceed the maximum supply, a demand response such as requesting the consumer to reduce power usage or limiting the power usage Implementation of is important. As a demand control system for realizing such a demand response, there is a method disclosed in Patent Document 1. In Patent Document 1, a demand response is realized by simultaneously broadcasting a power saving request notification to consumers in a specific area. More specifically, when the amount of power demand in a specific area managed by a power company exceeds a predetermined threshold, a power saving request is sent from the power company to the customer via a communication line. When the amount of power demand in the area falls below the threshold, a demand response can be made by sending a power saving cancellation by simultaneous broadcasting.

JP 2002-345177 A

  According to the technique described in Patent Literature 1, in order to achieve a supply and demand response when power supply is tight, all customers in a specific area are requested to save power by simultaneous broadcasting. Here, in the case where the expected power demand suppression effect is not obtained even though the power saving request is made, as a urgent measure, the restriction of power demand with high forcing or the stop operation is performed. However, some consumers do not want to stop power supply. For example, hospitals and consumers who use medical devices (for example, life support devices) that need to be energized at all times in the home may cause life-related situations due to the suspension of power supply. For such customers, it is not desirable to stop the power supply.

  However, in the technique of Patent Document 1, since the electric power demand is restricted and released all at once, the control for each individual consumer is not considered. Therefore, in the technique of Patent Document 1, it is not possible to know where on the power distribution system a consumer who does not want to stop such power supply belongs. Therefore, there is a problem that it is difficult to appropriately limit or stop the power supply.

  Accordingly, an object of the present invention is to ensure power supply to consumers whose power supply is not desired to be restricted by a simple device, and to enable appropriate and efficient power supply restriction / stop operation in an emergency. It is in.

  In order to achieve the above object, the present invention manages the positional relationship of consumers on the distribution network when performing a supply / demand response in the event of tight power supply, particularly when performing a power supply restriction / stop operation in an emergency. Also, feeders that exist in various facilities on the power distribution network while ensuring power supply to consumers who are not desired to restrict power supply by associating the power supply cutoff availability information for each consumer acquired in advance. By appropriately operating switches such as switches and section switches, the power supply can be efficiently limited and stopped in an emergency.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to perform restriction | limiting and interruption | blocking operation | movement of the electric power supply with respect to the wide area | region in an emergency, ensuring the electric power supply with respect to the consumer whose restriction | limiting and interruption | blocking of electric power supply are not desirable.

<Overview of this example>
Next, an overall outline of processing for obtaining the effect of the present embodiment will be described with reference to FIGS. 2, 3, 4, and 5.

  An example in which this embodiment is actually applied will be described with reference to FIG.

  In this example, the customer management device 1001, the power distribution management device 1101, and the power information management device 1301 are applied as different devices, and communication between the devices is performed via a network 1901. The network 1901 is mainly intended for data transmission / reception, and may be a general communication network managed by a telecommunications carrier or a dedicated communication network independently managed by a power carrier. In addition to electronic information exchange, physical information exchange using a USB memory, a CD-ROM, or the like may be used. When two or all three of the three devices are applied as the same device, the network 1901 may be communicated via a bus in the device. On the other hand, one control device that directly controls the facilities on the distribution system is installed in each of the distribution facilities such as the distribution substation 2001, feeder 2002, section switch 2003, pole transformer 2004, and meter 2005. The control command from the power distribution management apparatus 1101 is received via the network 1902. The network 1902 is mainly for controlling facilities, and is often a dedicated line network managed by an electric power company, but may be a general line network managed by a communication company. The means is not limited to a wired system or a wireless system. Further, if the distribution facility has a communication function and a power supply cutoff control function in advance, the control device 1401 is not necessarily required, and the function of the distribution facility may be used.

  The overall outline of the processing operation of the present embodiment in the application configuration example will be described with reference to FIG.

  First, in step S301, customer information is registered in the customer information recording means 1003. This registration process is performed by the customer information management program 1004. Moreover, the information which becomes the basis of the consumer information is contract application information applied by the consumer himself. In addition, the registration process may be started unconditionally after receiving an application from a consumer. For example, the registration process is started after undergoing some examination and receiving the customer's acceptance of the examination result. May be. In the examination, for example, when the interruption of the power supply is “permitted” or “impossible”, the power usage fee in an emergency when the power supply is tight or when it is not normal is calculated according to the power unit price table, and the calculation is performed. A method of presenting the result to the customer may be used. Next, in step S302, the cutoff prohibition information for each facility on the distribution system is created and registered. The creation process is performed by the block prohibition information creation program 1304, and the registration process is performed by the block prohibition information management program. Then, in step S304, it is determined whether or not to perform the operation of limiting / cutting off the power demand of a wide area consumer, which is an urgent measure due to power supply tightness. This determination may be performed mechanically and automatically, or may be performed manually. If it is determined that the power demand is restricted or cut off, in step S304, the distribution management device 1101 issues a control command, and the control device 1401 of each distribution facility that has received the control command actually The power supply is cut off.

  Next, an image of the effect obtained by the processing operation of the present invention shown in FIG. 3 will be described with reference to FIGS.

  FIG. 4 is an image diagram showing a power distribution system in a specific area. Among the consumers connected to the distribution system in this region, for example, railway operators 4001 and data center operators 4002 are considered to have extremely large human and economic damage when the power supply is cut off. Therefore, it is not desirable to cut off the power supply even in an emergency where the power supply is tight. In addition to the large-volume customers described above, for example, customers such as relatively small hospitals 4003 and general customers 4004 and 4005 who operate life support devices cut off the power supply even in an emergency. In such a case, it is possible to cause enormous human damage, so it is not desirable to cut off supply to these customers. As one of the means to solve this problem, for example, a meter or a control device having a communication function and a power cut-off function is installed for all consumer households, and supply cut-off control is performed for each household through the device. However, if this control operation is performed simultaneously for hundreds of thousands to millions of households, the expected power demand suppression effect can be obtained by a desired time due to the occurrence of congestion, etc. There is a risk of not being able to.

  Therefore, in the present invention, when performing an emergency power supply restriction / cutoff operation, the power supply cut-off measures described above ensure the power supply to undesired consumers, and on top of that, the higher-level equipment of the distribution system as much as possible The purpose is to obtain the power demand effect that is efficiently expected in a short period of time.

  For example, the distribution substation 4101 has two feeders 4201 and 4202. At this time, since there is no customer who has applied for non-blocking among the consumers connected to the lower level of the feeder 4101, the feeder 4201 is blocked in an emergency so that each household of the lower level consumers The objective can be achieved without the need for a shut-off operation. On the other hand, since the customer 4003 connected to the feeder 4202 has previously applied for the non-blocking, it cannot be blocked by the feeder 4202. In this case, in order to secure the power supply to the customer 4003, as an emergency shut-off measure, a shut-off operation is directly performed on the measuring instrument of the customer 4006. Further, since there is a customer 4004 whose supply is not desired to be cut off even in a customer connected to a lower level of the feeder 4203, the feeder 4203 cannot be cut off. On the other hand, when the section switch 4301 connected directly below the feeder 4203 is seen, there is no consumer who has applied for non-blocking among the consumers connected to the lower section of the section switch. Therefore, as an emergency shut-off measure, the section switch 4301 can be shut off.

  FIG. 5 is a diagram logically showing only the interconnection relation of the distribution facilities with respect to the application image of the present invention described in FIG. In FIG. 5, the boxes indicate the distribution facilities one by one, and the circles and crosses displayed in the boxes are the above-mentioned cutoff prohibition information, and the circles are the distribution facilities where the supply cutoff measures in an emergency are prohibited. X indicates power distribution equipment that is permitted to shut off supply. For example, in FIG. 5, when seeing the cutoff prohibition information of the meter located in the lowest layer on the power distribution system, there are three meteres 5001, 5002, and 5003 in which supply cutoff is prohibited. This means that the place where the three measuring instruments are installed is managed or an application for non-blocking is received in advance from a resident consumer. Therefore, as described above, supply cutoff is also prohibited for the pole transformer 5101 which is the upper connection equipment of the measuring device 5001. Similarly, the section switch 5201 that is the upper connection facility of the pole transformer 5101, the feeder 5301 that is the upper connection facility of the section switch 5201, and the distribution substation 5401 that is the upper connection facility of the feeder 5401 are also cut off. Is prohibited. On the other hand, since the consumer corresponding to the measuring instrument 5002 is a high-voltage consumer, it receives power supply directly from the feeder. However, since the upper level connection facility of the measuring instrument 5002 is the feeder 5302, the feeder is also cut off in the same way. It is forbidden. In this way, information indicating whether or not the power supply can be shut off in an emergency is provided for each power distribution facility, which is cut-off prohibition information, which is created by the cut-off prohibition information creation program 1304 and is blocked by the cut-off prohibition information management program 1305 It is recorded in the information recording means 1303. Further, the information necessary for creating the blockage prohibition information is the customer information recorded in the customer information recording unit 1003, and is recorded in the facility information recording unit 1103. It is the installation information of the distribution equipment such as feeders and section switches, which is the installed equipment information, and the installation location of the measuring equipment which is the lowest equipment. Further, the power information management device 1101 issues a control command based on the created cutoff prohibition information, and the control device 1401 that receives the control command performs actual facility control, thereby achieving an emergency demand response.

  In the following, a method for creating blocking prohibition information corresponding to step S302, and a control command issuance and control execution method corresponding to step S304 will be described with reference to the drawings.

<Necessary information for creating blocking prohibition information>
Here, a method of creating the cutoff prohibition information for each distribution facility will be described with reference to FIGS. 6 to 11 and 18 to 22 correspond to the logical conceptual diagram of the power distribution system of FIG.

  An example of customer information recorded in the customer information recording unit 1003 will be described with reference to FIG.

  FIG. 6 is an example of a customer information table recorded in the customer information recording means 1003. For example, the customer who is assigned the ID “C00001” described in the row 6001 has the application of the contract location ID “P00001” corresponding to the location, and has applied for blocking as the blockability information at the time of application. The blocking prohibition flag is recorded as “True”. Similarly, the customer who applied for the non-blocking at the time of application includes a customer whose customer ID described in the row 6002 is “C00012” and a customer whose customer ID described in the row 6003 is “C00018”. A total of three people. Similarly, other customer information is created through the customer information management program 1004 based on an application from the customer and registered in the customer information recording means 1003.

  Next, the facility information recorded in the facility information recording unit 1103 will be described with reference to FIGS.

  FIG. 7 is an example of a meter information table that records the relationship between the meter installed in each consumer household and its installation location. For example, the row 7001 indicates that the measuring instrument with the ID “M00001” is installed at the place with the ID “P00001”. In some cases, two or more different measuring instruments are installed in the same place, such as a factory or a two-family house. In such a case, for example, as in rows 7002 and 7003, IDs “M00002” and “M00003” are used. "Are both linked to the location of the same ID" P00002 "and recorded.

  FIG. 8 is an example of the pole transformer information table in which the connection relation between the pole transformer and the place where power is drawn from the transformer is recorded. For example, row 8001 indicates that the pole transformer with ID “T00001” has drawn a lead-in wire to the location with ID “P00001”. Further, as in the case of the feeder 5302 in FIG. 5, there is a case where power is directly drawn from the feeder to a certain place without using a pole transformer. Even in such a case, the feeder 5302 is regarded as a virtual pole transformer, and is directly linked to the place and recorded in the pole transformer information table. For example, the ID “F00003” shown in the row 8001 corresponds to the feeder 5302 in FIG. 5, but the feeder with the ID “F00003” is directly linked to the location of the ID “P00011” and recorded in the table. The

  FIG. 10 is an example of a feeder information table in which the connection relationship between the feeder and the section switch is recorded. In this table as well, as in the case of the measuring instrument information table and pole transformer information table, in principle, the table is a table that records the connection relationship between the feeder and the section switch. However, as described above, the location of the ID “P00011” On the other hand, the power line is directly drawn from the feeder of ID “F00003”. Accordingly, in the feeder information table as well, as shown in the row 10001, the feeder with the ID “F00003” is regarded as the virtual section switch, and the location of the ID “P00011” is recorded in association with each other. .

  FIG. 9 is an example of the section switch information table that records the connection relationship between the section switch and the pole transformer.

  FIG. 11 is an example of a substation information table that records connection relationships between distribution substations and feeders. 9 and 11, in principle, for example, the section switch information table includes the section switch and the pole transformer, as in the weighing instrument information table, the pole transformer information table, and the feeder information table. The connection relation is recorded, and the substation information table records the connection relation between the distribution substation and the feeder. For example, when the power line is drawn directly from the section switch to a certain place, the same as described above In addition, the location is regarded as a virtual pole transformer and is linked to the section switch and recorded in the section switch information table.

  In this embodiment, the table is separated for each distribution facility, but the information to be recorded in this table is a parent-child relationship that occurs when each distribution facility is connected by a power line, and this parent-child relationship can be recorded. If so, the information may be managed in any configuration. For example, the tables shown in FIGS. 7 to 11 may be combined into one table.

  In addition, regarding the pole transformer information table, in this embodiment, the power line lead-in place is regarded as the connection destination and associated with the pole transformer, but from the viewpoint of distribution equipment, the pole transformer is originally In order to connect to a measuring instrument, the measuring instrument may be recorded as a connection relation to the pole transformer. However, in the case of the pole transformer table as described above, in view of the fact that the measuring instrument is replaced relatively frequently in actual operation, each time the measuring instrument is replaced, the measuring instrument information table and the column Two tables in the upper transformer table must be updated. On the other hand, if it is a pole transformer table that records the pole transformer and the destination location linked to each other, there is no change in the location even if the meter is replaced. This information update may be performed only by the measuring instrument information table, that is, the pole transformer information recording method in the present embodiment contributes to facilitating information management and speeding up the processing.

<Example of blocking prohibition information>
Next, a method for creating the cutoff prohibition information for each power distribution facility and an example of the creation result information will be described with reference to FIGS.

  First, an example of the blocking prohibition information created as a result of the processing will be described with reference to FIGS. 18 to 22 correspond to the logical conceptual diagram of the power distribution system shown in FIG. 5, and will be described with reference to FIG. 5 as appropriate.

  The blockage prohibition information referred to in the present embodiment includes a facility ID that uniquely identifies a distribution facility such as a feeder or a section switch, and a blockage prohibition flag that expresses whether or not blockage is prohibited by a Boolean value of “True” or “False”. As an example, assume that the information is expressed as a pair of two types of information. The cutoff prohibition flag “True” means that the emergency supply cutoff is prohibited, and “False” means that the emergency supply cutoff is permitted.

  FIG. 18 is an example of a measuring instrument shut-off prohibition flag table showing shut-off prohibiting information of each measuring instrument. In line 18001, the shut-off prohibiting flag of the measuring instrument with ID “M00001” is “True”. This means that the power supply is prohibited from being interrupted even at times. On the other hand, in the row 18002, the cutoff prohibition flag of the measuring instrument with ID “M00002” is “False”, which means that the cutoff of the power supply is permitted in an emergency. The state of the shut-off prohibition flag of these measuring instruments affects the upper equipment of the distribution system. For example, for the measuring instrument with ID “M00001” whose shut-off prohibition flag is “True”, it can be seen from the line 7001 in FIG. 7 that the installation place is the place with ID “P00001”, and the line 8002 in FIG. Thus, it can be seen that the pole transformer that has a lead-in wire at the place of ID “P00001” is a transformer of ID “T00001”. Accordingly, the cutoff prohibition flag of the pole transformer with the ID “T00001” is also “True”, and this is recorded in the row 19001 of the pole transformer cutoff prohibition flag table shown as an example in FIG. Similarly, it can be seen from the row 9001 in FIG. 9 that the power distribution facility located above the ID “T00001” is the section switch having the ID “S00001”. Therefore, the cutoff prohibition flag of the section switch is also “True”. . This is recorded in line 20001 in FIG. Further, since the distribution facility located above the section switch with ID “S00001” is found to be a feeder with ID “F00001” from the row 10002 in FIG. 10, the shut-off prohibition flag of the feeder is also set to “True” as described above. This is recorded in the row 21001 in FIG. Further, since the distribution facility located above ID “F00001” is identified as the distribution substation with ID “DSS00001” from the row 11001 in FIG. 11, this also similarly sets the shut-off prohibition flag of the substation. “True” is recorded in the row 22001 of FIG.

  On the other hand, the shut-off prohibition flag of the measuring instrument with ID “M00002” is “False”, but this flag value also affects the upper power distribution equipment as described above. For example, in the same manner as described above, the power distribution equipment located at the upper position of the ID “M00002” is shown in FIG. 8 to FIG. 11, and the pole transformer of the ID “T00002”, the ID “S00001” in order from the lower order. It can be seen that this is a section switch of ID “F00001”, and a distribution substation of ID “DSS00001”. If processing is performed in the same manner as described above, the shut-off prohibition flags of these four distribution facilities are all “False”. However, the present invention ensures that the power supply is secured to the equipment whose shut-off prohibition flag is “True”. As a general rule, in other words, if there is at least one facility with a “True” shut-off prohibition flag in each facility connected to each distribution facility, the shut-off prohibition flag for that facility is “True”. To do. For example, it can be seen from row 9001 and row 9002 in FIG. 9 that the subordinate equipment connected to the section switch with ID “S00001” is a pole transformer with IDs “T00001” and “T00002”. However, as described in the row 19001 in FIG. 19, the cutoff prohibition flag of the pole transformer with ID “T00001” is already “True”. Therefore, in accordance with the principle of the present invention, the cutoff prohibition flag of ID “S00001” is set to “True”. However, the value of the blocking prohibition flag is not changed. For example, when a customer with ID “C00001” reapplies for blocking without permission without changing the contract location, the blocking prohibition flag with ID “M00001” is also included. “True” is changed to “False”, and accordingly, the cutoff prohibition flag of the pole transformer with ID “T00001” is also changed to “False”. At this time, if the cutoff prohibition flag of ID “T00002” is also “False”, the cutoff prohibition flag of higher-level ID “S00001” is also changed from “True” to “False”.

  In this embodiment, the shutdown prohibition information is recorded independently for each distribution facility, but the essence of the shutdown prohibition information is a simple method of shutting down or being permitted in an emergency. For example, all the blocking prohibition information may be recorded in one table, or two blocking prohibition tables and a blocking permission table are prepared, and the facility IDs are respectively provided. It is also possible to record only.

<Procedure for creating blockage prohibition information>
Next, a method for creating a blocking prohibition flag included in the blocking prohibition information will be specifically described with reference to FIGS. 12 to 17 and FIG. There are the following four embodiments for creating the blocking prohibition flag.

In the first embodiment, when creating a shut-off prohibition flag for each distribution facility, in this embodiment, from the shut-off prohibition flag of the measuring instrument, which is the lowest level equipment in the distribution system, to the substation flag for distribution, which is the highest level equipment, In this embodiment, the creation processing is performed synchronously at one time, and the creation processing is performed inside a set of computers such as a mainframe. An example of the processing flow in the present embodiment will be described with reference to FIGS. 12 to 17. First, FIGS. 12 to 14 are processing flows in the case of creating the blocking prohibition flag “True” in the present embodiment. . This process is executed by the blocking prohibition information creation program 1304 in FIG. In the following description, a specific explanation will be given by taking as an example a case where a customer with ID “C0209” re-applies for blocking as “impossible”.

  First, in step S1201, the ID of the customer for which a block prohibition flag is to be created is set in a variable “C”, and in step S1202, the customer's contract location from the customer information table using the customer ID “C” as a search key. The ID is acquired and stored in the memory as a variable “P”. For example, here, a customer with ID “C00029” re-applying as “impossible” for blockability is taken as an example, and if ID “C0209” is stored in “C”, row 6004 in FIG. Thus, since the place ID “P0209” can be acquired, the ID is stored in the memory as “P”. At this time, if the contract location ID cannot be acquired, it is a new contract, so a new contract location ID is issued and stored in the memory as a variable “P”. Next, in step S1203, the measuring instrument ID associated with the location is acquired from the measuring instrument information table using “P” as a search key, and stored in the memory as a variable “M”. As a search key, the flag value of the measuring instrument is acquired from the measuring instrument cutoff prohibition flag table, and the flag value is rewritten to “True”. For example, when FIG. 7 which is a measuring instrument information table is searched using the place ID “P00029” as a search key, “M00030” can be acquired as the measuring instrument ID from the row 7004, and the ID is stored in the memory as the variable “M”. To do. Next, when the weighing machine ID “M00030” is searched using the search key as a search key in FIG. 18 which is the weighing machine cutoff prohibition table, “False” is acquired as the flag value, and this is rewritten to “True”. Subsequent processing enters processing for sequentially rewriting the shut-off prohibition flag of the upper distribution equipment. For example, in step S1205, the pole transformer ID “T00018” is acquired from the row 8003 of FIG. 8 which is the pole transformer information table using the place ID “P0209” as a search key. In step S1206, the flag value “False” is acquired from the row 19002 in FIG. 19 which is the transformer cutoff prohibition flag table using the pole transformer ID “T00018” as a search key. Here, in the next step S1207, it is determined whether or not the flag value is “True”. This is because if the acquired flag value is “True”, the shut-off prohibition flag of the power distribution equipment higher than the transformer is also “True” in the processing in this embodiment. This is because it is not necessary to perform the subsequent flag rewriting process, and therefore the processing speed can be expected. That is, if the acquired cutoff prohibition flag of the pole transformer is “True”, the creation process of the “True” flag ends here, but the acquired flag value is “False” in this example. Therefore, in the next step S1208, the flag value in the row 19002 in FIG. 19 which is the transformer cutoff prohibition flag table is rewritten to “True”, and the process proceeds to the next step. Thereafter, similarly, the value of the shut-off prohibition flag of the host equipment is sequentially rewritten to “True”. For example, in FIG. 13, steps S1301 to S1304 are rewrite processing of the block switch prohibition flag value, and steps S1305 to S1308 are rewrite processing of the feeder blockage prohibition flag. Further, in FIG. 14, steps S1401 to S1404 are rewriting processing of the shut-off prohibition flag of the distribution substation. In steps S1303, S1307, and S1403, the flag value immediately after being acquired from the shut-off prohibition flag table of each distribution facility is determined. If “True”, the process ends at that time, and if “False”. After rewriting to “True”, the process proceeds to the rewrite processing of the shut-off prohibition flag of the upper power distribution equipment.

  The above is an example of a method for rewriting the blocking prohibition flag “False” to “True” in the first embodiment. Next, an example of a method for rewriting the blocking prohibition flag “True” to “False” will be described with reference to FIGS. 15 to 17. In the following description, a specific description will be given by taking as an example a case where a customer with ID “C00018” reapplies for “permitted” for blocking.

First, in step S1501, the ID of the customer for which the block prohibition flag is to be created is set to a variable “C”. In step S1502, the customer's contract location is searched from the customer information table using the customer ID “C” as a search key. The ID is acquired and stored in the memory as a variable “P”. For example, here, a customer with ID “C00018” reapplying as “permitted” for blockability is taken as an example, and if ID “C00018” is stored in “C”, the customer information table, row 6003 in FIG. Thus, since the place ID “P00018” can be acquired, the ID is stored in the memory as “P”. At this time, if the contract location ID cannot be acquired, it is a new contract, so a new contract location ID is issued and stored in the memory as a variable “P”. Next, in step S1503, the measuring instrument ID associated with the location is acquired from the measuring instrument information table using the “P” as a search key, stored in the memory as a variable “M”, and further “M”. As a search key, the flag value of the measuring instrument is acquired from the measuring instrument cutoff prohibition flag table, and the flag value is rewritten to “False”. For example, when the place ID “P00018” is used as a search key to search FIG. 7 which is a measuring instrument information table, “M00019” can be acquired as the measuring instrument ID from the row 7005, and the ID is stored in the memory as the variable “M”. To do. Next, when the meter ID “M00019” is retrieved as a search key with respect to FIG. 18 which is the meter blockage prohibition table, “True” is acquired as the flag value, and this is rewritten as “False”. Subsequent processing enters processing for sequentially rewriting the shut-off prohibition flag of the upper distribution equipment. For example, in step S1505, the pole transformer ID “T00011” is acquired from the row 8004 of FIG. 8 which is the pole transformer information table using the place ID “P00018” as a search key. In step S1506, the flag value “True” is acquired from the row 19003 in FIG. 19 which is the transformer cutoff prohibition flag table using the pole transformer ID “T00011” as a search key. Here, in the next step S1507, it is determined whether or not the flag value is “False”. This is because if the acquired flag value is “True”, the shut-off prohibition flag of any distribution equipment connected to the lower level of the transformer is similarly “True” in the processing in this embodiment. This is because in this case, the cutoff prohibition flag of the transformer cannot be rewritten to “False”. In this example, since the acquired flag value is “True”, in S1601 in FIG. 16, which is the next step, the transformer information table is searched using the ID “T” of the transformer as a search key. After acquiring all the measuring instrument IDs connected to the lower level and storing them in the memory as a list “MList”, in steps S1602 and S1603, using the “MList” as a key, from the measuring instrument cutoff prohibition flag table, It is determined whether or not “True” exists in the shut-off prohibition flag of all the distribution facilities to be connected. For example, the transformer information table of FIG. 8 is searched using the transformer ID “T00011” as a search key, and the IDs of the places “P00017” and “P00018” are acquired as the lower equipment IDs from rows 8004 and 8005. . Thereafter, FIG. 6 which is a customer information table is searched using the place IDs “P00017” and “P00018” as search keys. In FIG. 6 in this example, the blocking prohibition flag of the place ID “P00018” is described as “True”, but at the time of re-application of blocking permission from the customer, which is a stage before the start of step S1501. The blocking prohibition flag in the row has been rewritten to “False”. Therefore, in the present embodiment, the blocking prohibition flags of the place IDs “P00017” and “P00018” are all acquired as “False”. That is, since it has been confirmed that all the cutoff prohibition flags of the lower-level equipment connected to the transformer “T00011” are “False”, the cutoff prohibition flag of the transformer is rewritten to “False” in step S1604. Thereafter, similarly, the value of the shut-off prohibition flag of the host equipment is sequentially rewritten to “False”. For example, in FIG. 16, steps S1605 to S1611 are rewrite processing of the section switch cutoff prohibition flag value, and in FIG. 17, steps S1701 to S1707 are processing to rewrite the feeder cutoff prohibition flag. In addition, steps S1708 to S1714 are rewriting processing of the shut-off prohibition flag of the distribution substation. In steps S1607, S1703, and S1710, the flag value immediately after being acquired from the shut-off prohibition flag table of each distribution facility is determined. If “False”, the process proceeds to the process of creating and updating the shut-off prohibition flag of the higher-level equipment. , If “True”, the blockage prohibition flag of all facilities connected to the lower level of the distribution facility is acquired, and if “True” exists in any one of the blockage prohibition flags, the distribution facility If the shutdown prohibition flag is also set to “True”, and the shutdown prohibition flags of the acquired lower-level equipment are all “False”, the upper cutoff point after rewriting the shutdown prohibition flag of the distribution equipment to “False” It shifts to the rewrite processing of the shut-off prohibition flag of the distribution equipment.
The above is the method for creating the blocking prohibition flag in the first embodiment, but the timing for starting this processing may be, for example, the point in time when an application for blocking permission is received from a customer, or at certain time intervals Alternatively, it may be performed at an arbitrary timing. However, when it is performed at regular time intervals or at arbitrary timing, the block prohibition flag in the customer information table shown in FIG. 6 is updated to the latest value in advance, and the target customer in step S1201 It is desirable to target only customers who have applied for after the time when the blocking prohibition flag creation process is performed.

  In the second embodiment for creating the shut-off prohibition flag, each distribution facility executes its own shut-off flag autonomously and asynchronously with the flag creation processing of other equipment, and the creation processing is performed on the mainframe or the like. It is the form which processes inside a set of computers. An example of the processing flow in this embodiment will be described with reference to FIG.

  First, in step S2301, the ID of the facility for which the cutoff prohibition flag is to be created is stored in the memory as a variable “Pa”. Hereinafter, the facility for which the cutoff prohibition flag is created is referred to as “parent facility”. For example, here, a measuring instrument having an ID “M00002” is selected as the parent facility, and the ID is stored in “Pa”. Next, in step S2303, the facility information table of the parent facility is searched using “Pa” as a key, and all child facility IDs connected to the parent facility are acquired. For example, when “M00002” is searched for in the weighing instrument information table shown in FIG. 7, the location ID “P00002” is acquired as the ID of the child facility. Next, in step S2306, it is determined whether the ID of the child facility is a place ID. This is because the blockage prohibition flag associated with the location is recorded in the customer information table, not the blockage prohibition flag table for each facility. It is because it is necessary to access. In this example, since the acquired child facility ID is the location ID, in step S2307, the customer information table of FIG. 6 is searched using the ID “P00002” as a key to acquire the blocking prohibition flag. . As a search result, “True” is acquired as the blocking prohibition flag value from the row 6001 in FIG. Finally, in step S2309, it is determined whether or not the child facility shut-off prohibition flag is “True”. If it is “True”, the parent facility shut-off prohibition flag is set to “True” in step S2310. Rewrite and exit. This is the principle of the present invention. If there is any one of the lower-level facilities on the power distribution system whose shut-off prohibition flag is “True”, all the shut-off prohibition flags of the higher-level facilities are also “True”. This is to follow the principle of

  The above is the description of the second embodiment of the method for creating the cutoff prohibition flag. In the present embodiment, the creation of the shut-off prohibition flag is executed independently and asynchronously for each distribution facility. For example, a plurality of program processes may be generated and executed simultaneously in order to speed up the processing. In the first embodiment and the second embodiment, since all processing is performed by a set of computers, data exchange between steps is performed by, for example, communication between memories. The

  The third embodiment for creating the cutoff prohibition flag is created synchronously from the cutoff prohibition flag of the measuring instrument that is the lowest level equipment in the distribution system to the distribution substation flag that is the highest level equipment, and It is a form which performs the said flag creation process using the control apparatus installed for every power distribution installation.

  In the present embodiment, for example, the shut-off prohibition information creation program 1404 provided in the control device 1401 installed in each distribution facility mainly performs three processing operations. The first processing operation is reception of a cutoff prohibition flag from the lower-level equipment. The second process is updating the shutdown prohibition flag of the own equipment. If the cutoff prohibition flag received from the lower power distribution equipment is “True”, the cutoff prohibition flag value of the own is set to “True”, and the shutdown prohibition information recording unit 1403 itself is set via the cutoff prohibition information management program 1405. Record the value of the block prohibition flag. On the other hand, when the cutoff prohibition flag received from the lower power distribution facility is “False”, the shutdown prohibition flag value of each facility is inquired and collected from all the lower power distribution facilities connected to the own facility. If at least one of the collected blocking prohibition flags includes “True”, its own blocking prohibition flag value is also “True”, and all collected blocking prohibition flags are “False”. In this case, the own blocking prohibition flag value is also set to “False”, and the own blocking prohibition flag value is recorded in the blocking prohibition information recording unit 1403 via the blocking prohibition information management program 1405. The third processing is transmission of the shut-off prohibition flag value of the own equipment to the control device 1401 of the distribution equipment connected to the higher rank of the own equipment. In the present embodiment, the first processing start condition is when a cutoff prohibition flag value is received from any of the lower-level equipment connected to the own equipment. However, in this embodiment, since there is no subordinate equipment of the measuring instrument, the first processing start condition for the measuring instrument is transmitted from, for example, the power information management device 1301 or the customer management device 1001. This is when the blocking prohibition flag value of the installation location is received. As described above, the processing operations from the first to the third are performed by the control device 1401 installed in each distribution facility, so that the highest level facility can be changed from the shut-off prohibition flag of the measuring device which is the lowest level facility in the distribution system. It is possible to create and update up to a certain distribution substation flag synchronously at once.

  In the fourth embodiment for creating the shut-off prohibition flag, each distribution facility executes its own shut-off flag autonomously and asynchronously with the flag creation processing of other facilities, in addition to the flag creation processing, It is the form performed using the control apparatus installed for every power distribution equipment.

  In the present embodiment, for example, the shutdown prohibition information creation program 1404 provided in the control device 1401 installed in the power distribution facility has only one process, and the subordinate facility connected to the own facility By monitoring the shutdown prohibition flag, only the shutdown prohibition flag value of the own equipment is updated. That is, the control device 1401 of each distribution facility acquires all the shutdown prohibition flags of the lower-level equipment connected to the own facility, and if “True” exists in any one of the acquired shutdown prohibition flags, If the equipment shutdown prohibition flag is also set to “True” and all of the acquired shutdown prohibition flags are “False”, the shutdown prohibition flag of the own equipment is also set to “False”, and the shutdown prohibition information management program 1405 is used to prohibit the shutdown. The information recording unit 1403 records the value of its own blocking prohibition flag. In the present embodiment, the first processing start condition may be any timing or periodic. The control device 1401 of each distribution facility performs the processing asynchronously and autonomously, so that the cutoff prohibition flag of each distribution facility can be created and updated.

  The above is the description of the four embodiments regarding the method of creating the blocking prohibition flag. Here, the necessary information in the second and third processes in the third embodiment, the lower and upper equipment information of the own equipment, and the information necessary in the process in the fourth embodiment For example, the equipment information below the own equipment includes, for example, equipment ID for uniquely identifying each equipment on the system and address pair information for uniquely identifying each equipment on the communication network. It is recorded in the facility information recording means 1411 provided in the device 1301, and with this, the control device 1401 of each distribution facility enables the lower and upper facilities of the own facility to be identified. However, the means for the control device 1401 of each distribution facility to identify the lower and upper facilities of the own facility is not limited to the above-described method. For example, each control device 1401 can manage the distribution as necessary. A method of obtaining the information by inquiring of the device 1101 may be used.

  In the present example, the recording location of the blocking prohibition flag in the third and fourth embodiments is the blocking prohibition information recording unit 1403 provided in each control device 1401. It is not limited to an example, and for example, it may be recorded in the cutoff prohibition information recording unit 1303 provided in the power information management apparatus 1301. The timing at which the block prohibition flag is transmitted to the block prohibition information recording unit 1303 may be the timing at which each control device 1401 determines the block prohibition flag of its own equipment, or may be at an arbitrary timing or periodically.

  In addition, the method of creating the cutoff prohibition flags for all the distribution facilities having connection relations described in the first and third embodiments at once and synchronously is the matching of the cutoff prohibition flags between the distribution facilities. However, when there are a large number of target distribution facilities, there is a demerit that it takes a long time to create a blockage prohibition flag. On the other hand, as described in the second and fourth embodiments, each distribution facility can create its own facility cutoff prohibition flag only autonomously and asynchronously. For example, the distribution prohibition flag of a certain distribution facility "A" Immediately after selecting “False”, if the subordinate equipment “B” of the power distribution equipment “A” rewrites the shut-off prohibition flag to “True”, until the power distribution equipment “A” next performs the shut-off prohibition flag creation process, There is a demerit that it is not possible to guarantee the consistency of the shut-off prohibition flag between each distribution facility, such as the fact that the shut-off prohibition flag of the equipment “A” is originally “True” is operated as “False”. Even when there are a large number of distribution facilities, there is an advantage that the time required for the processing unit for creating the cutoff prohibition flag is small.

  Further, in the above embodiment, the power supply cutoff application has been described for each customer. However, the present invention is not limited to this, and for example, the application of the cutoff permission for each region to which a plurality of consumers belong. It is also applicable to cases. For example, for a peripheral area “COM00002” of a certain public facility, when it is desired to block power supply to “impossible”, rows 6006, 6007, 6008, 6002, 6009, 6010, 6005 in FIG. , And the customer's blockage prohibition flag of 6003 are updated as “True”, and then the blockage prohibition flag creation method described in the first to fourth embodiments is connected to the region “COM00002”. You may create and update the cutoff prohibition flag for all distribution facilities.

  Further, the first to fourth embodiments are not limited to independent embodiments. For example, a cutoff prohibition flag such as a measuring instrument or a pole transformer, which is considered to have a relatively large number of facilities. Is created according to the fourth embodiment, and a shut-off prohibition flag such as a distribution substation or feeder considered to have a relatively small number of facilities may be created according to the first embodiment.

<Control method based on blocking prohibition information>
Next, a method for controlling power distribution equipment such as feeders and section switches based on the cutoff prohibition flag created by the cutoff prohibition flag creation method described in the above four embodiments will be described. In addition, there are the following two embodiments of the distribution facility control method based on the cutoff prohibition flag.

  The first embodiment is a method of controlling by directly transmitting a control command to a distribution facility at the highest level of each distribution system among distribution facilities whose cutoff prohibition flag is “True”. The method mainly performs two processing operations. The first processing operation is determination of the facility to be shut off and is executed by the facility control program 1105 provided in the power distribution management device 1101. An example of this processing flow will be described with reference to FIG.

  First, in step S2401, all the IDs of the power distribution equipment on the top of the power distribution system are recorded in the memory as a list “IDList”. For example, since the uppermost distribution facility in this embodiment is a distribution substation, the IDs “DSS00001”, “DSS00002”, and “DSS00003” are stored in the memory as “IDList” from FIG. Next, in step S2402, one ID is selected from “IDList”, and after determining the type of the ID in step S2403, in step S2404, the distribution facility is selected from the cutoff prohibition flag table corresponding to the distribution facility of the ID. Is obtained and stored in the memory as a variable “F”. For example, when the ID “DSS00001” is selected, since the ID is the ID of the distribution substation, “True” is set as the cutoff prohibition flag value from the row 22001 in FIG. 22 which is the cutoff prohibition flag table of the distribution substation. To store “True” as a variable “F”. Next, in step S2405, it is determined whether or not the value of the acquired blocking prohibition flag is “True”. If it is “True”, in step S2406, the list “ShutDownList” in the memory is used as the facility ID to be blocked. To remember. For example, since the cutoff prohibition flag of the distribution substation with the acquired ID “DSS00001” is “True”, the ID “DSS00001” is stored in the list “ShutDownList”. On the other hand, if the cutoff prohibition flag acquired in step S2404 is “False”, in step S2407, all IDs of lower-level facilities connected to the facility are acquired and stored in the memory as a list “IDList2”. For example, when the ID “DSS00003” is selected in step S2402, “False” is acquired as the cutoff flag value from the line 22002 of FIG. 22 in step S2404. Therefore, “F00005” and “F00006” are acquired from the rows 11002 and 11003 in FIG. 11 as the distribution substation information table as all subordinate equipment connected to the ID “DSS00003”, and the list “IDList2 in the memory” is obtained. To remember. After the processing from step S2402 to S2408 is repeated for the number of facilities input in step S2401, "IDList" is overwritten and updated with "IDList2" in step S2410, and the processing is executed again from step S2402. To go. Finally, when there is no equipment ID stored in the list “IDList2” in step S2408, “ShutDownList”, which is a list of equipment to be shut down, is output as control information in step S2410. As described above, the shutdown prohibition flag is determined. If “True”, the ID of the distribution facility is extracted. On the other hand, if “False”, the determination of the cutoff prohibition flag is repeated for the subordinate facilities of the facility. By executing in order from the top of the power distribution system, it is possible to extract only the power distribution equipment at the top of each power distribution system from among the power distribution equipment whose shut-off prohibition flag is “True”. is there.

  The above is the first process in the first embodiment. As the second process, a control command is directly transmitted to the control device 1401 of the distribution facility described in the created control information. Thus, the control in the present embodiment is performed. In addition, since this method realizes the shut-off operation to all consumers connected to the equipment by shutting off the upper power distribution equipment as much as possible, for example, in order to obtain the same effect, It is possible to reduce the data amount of the control command to be transmitted and the number of control operations compared with the method of transmitting the control command to the device.

  In the second embodiment of the distribution facility control method based on the cutoff prohibition flag, the distribution management device 1101 transmits a control command without specifying the control target facility, and the control device 1401 of each distribution facility that has received the control command This is a method of autonomous determination. For example, the power distribution management device 1101 broadcasts, as a control command, only a signal indicating the execution of a shut-off operation to all power distribution facilities or a specific system. Next, the control device 1401 of each distribution facility that has received the control command refers to its own shut-off prohibition flag value from the shut-off prohibition information recording unit 1403. If “True”, the shut-off operation is executed, and “False” If so, the decision not to execute is made autonomously. This process is executed by the control execution program 1410 provided in each control device 1401.

  The above is the description related to the two embodiments in the control method of the distribution facility based on the cutoff prohibition flag, but the first and second embodiments are not limited as independent embodiments, For example, for measuring instruments and pole transformers that are considered to have a relatively large number of facilities, control is performed according to the second embodiment, while distribution substations that are considered to have a relatively small number of facilities For the feeder or the like, control may be executed according to the first embodiment.

  As mentioned above, although one Embodiment of this invention was described concretely, this invention is not limited to this, A various change is possible in the range which does not deviate from the summary. For example, in the above embodiment, a perfect tree structure is assumed as the structure of the power distribution system, but the present invention is also applicable when a part of the power distribution system has a ring structure. In this case, for example, there are cases where two power distribution facilities are connected above the power distribution facility whose cutoff prohibition flag is “True”. At this time, both of the upper two distribution facilities may be set to the cutoff prohibition flag “True”. For example, the number of all lower facilities connected to the upper two facilities is distributed The shut-off prohibition flag calculated by the equipment information recording means of the apparatus and having the smaller number of connected lower equipment may be set to “False”.

  In the above embodiment, the network that transmits the control command to the control device is described as using the control network. However, depending on the type of the control device, a general information communication network may be used. .

  In the above embodiment, the customer information management device, the power distribution management device, and the power information management device have been described as different devices. However, the present invention is not limited to this, and among the three devices, Two or all three may be the same device.

  In the above embodiment, the control device installed in each distribution facility is described as automatically executing control based on the control command received from the power distribution management device, but outputs a notification that the control command has been received. After outputting to the apparatus, the process may be waited, and then the final control operation may be manually performed via the input apparatus. Further, if the facility itself has a function equivalent to that of the control device described in the above embodiment, the function may be used.

  In the above-described embodiment, it has been described that the power supply of the distribution facility whose cut-off prohibition flag is “True” should not be cut off. However, the significance of the present invention is the consumer who should not cut off the power supply. As long as it does not deviate from this significance, the power supply may be cut off even if the cutoff prohibition flag is “True”. For example, for the distribution facility “A” whose shut-off prohibition flag is “True”, the facilities connected to the lower level of the facility have a power supply capability such as a solar power generator, a diesel generator, or a storage battery. The equipment to which the equipment is connected and which has the power supply capacity has a sufficient supply capacity to satisfy the demand of the consumer who cannot connect to the power supply connected to the power distribution equipment “A”. If power can be supplied to the consumer, the power supply to the power distribution facility “A” may be cut off.

  In the above-described embodiment, the cutoff prohibition flag is described as binary values of “True” and “False”, but may not necessarily be binary values. For example, there is a customer who may shut off when the degree of urgency is relatively low, such as a situation where the shutdown stop time is short, even among customers whose shutdown prohibition flag is “True” There is. In the above case, according to the urgency level of supply and demand tightness, for example, from level 1 that may be cut off even when the degree of urgency is relatively low, level 2 that may be cut off if the degree of emergency is moderate, the degree of urgency is very high A blocking prohibition flag may be created and managed with a continuous value such as level 3 that may be blocked only when the value is high. At this time, as a method of creating the shut-off prohibition flag for the upper power distribution equipment, for example, in the case of equipment having the shut-off prohibition flags of level “1” and “2” in the lower equipment, it is the highest value among the level values. “2” may be set as its own blocking prohibition flag. In addition, the power distribution management device can shut down only equipment having a shut-off prohibition flag equal to or lower than the level by issuing one of the level values 1 to 3 as a control command.

  Moreover, although the said embodiment demonstrated that the electric power supply of the distribution equipment whose interruption | blocking prohibition flag is "False" may be interrupted | blocked, it is not necessary to interrupt | block the electric power supply line of all the distribution facilities. . For example, when the measuring instrument “M001” and the measuring instrument “M002” are connected to the lower level of the pole transformer “T001”, the cutoff prohibition flags of the measuring instruments “M001” and “M002” are both set to “False”. ”, Both measuring instruments may be cut off. However, if the customer “C001” associated with the measuring instrument “M001” has equipment having power supply capability such as a storage battery or a solar power generator, in an emergency, for example, the measuring instrument “M002” In order to supply power to the customer “C002” associated with the power supply, it is not desirable to cut off the power supply lines of the measuring instruments “M001” and “M002”. In this case, for example, based on an application from a customer, the cutoff prohibition flag value of each of the customers “C001” and “C002” is changed from “False” to “ExceptionTrue”, and the cutoff prohibition flag of each facility is regenerated again. To do. Here, the flag value “ExceptionTrue” in this example means that the equipment is shut off but is not prohibited until the host equipment is shut down. Therefore, in the case of the above example, since the cutoff prohibition flag of the subordinate equipment of the pole transformer “T001” is “ExceptionTrue”, the cutoff prohibition flag of the pole transformer “T001” remains “False”. When the control command is issued again after the regeneration of the shut-off prohibition flag, the pole transformer “T001” is shut off, but the measuring instruments “M001” and “M002” are not shut off. Therefore, the consumers “C001” and “C002” Can be interchanged.

  In actual operation, for example, a customer such as a tenant in a building cannot be managed by an electric power company. Therefore, a direct control command is issued from the electric power company's power distribution management device to the power distribution equipment of each individual customer. However, the present invention is also effective in the above case. As a method for creating a block prohibition flag, for example, a block prohibition flag based on a block permission application of each tenant consumer in a building is first registered in a customer information management apparatus managed by a building owner. At this time, the contract location ID may be, for example, a building name or an identifier “PB001”. Next, from the customer information management device managed by the electric power company, the blockage prohibition flag of each customer at the location with the contract location ID “PB001” as a key to the customer management device managed by the building owner. If at least one “True” exists, the interruption prohibition flag of the consumer managed by the electric power company is also set to “True”. Thereafter, a cutoff prohibition flag for the distribution facility managed by each of the building manager and the power company is created. The distribution facilities managed by the power company at this time are, for example, distribution substations, feeders, section switches, pole transformers, and measuring instruments, as described in the above embodiment. The distribution facility to be managed is a control device such as a distribution control panel installed for each tenant consumer. In addition, for example, the control command issuance method in the building may be directly transferred to the control device installed in each tenant consumer or may be controlled with respect to the control device that manages the entire building. A method of transferring an instruction may be used. Further, in this example, it has been described that the building manager performs information management of each tenant consumer, creation of a blockage prohibition flag for building facilities, and issuance of a control command. However, for example, a third party service provider may perform the management. .

  According to the present embodiment, it is possible to ensure power supply to consumers who do not want to limit or cut off power supply, and to quickly and efficiently respond to demand by power cut-off operation over a wide area. become. For example, as an example, based on the location on the distribution system of a customer whose power supply is not desirable to be cut off, such as distribution substations, feeders, section switches, pole transformers, measuring instruments, etc. existing on the distribution system It is possible to realize a quick and efficient demand response by determining whether or not each power supply can be cut off for the power distribution facility, and executing power supply cut-off control based on the determination information.
