Description

  The present invention relates to a construction support system that supports construction involving power outage.

In order to supply electricity stably to customers (customers receiving electricity), electric power companies maintain and manage various facilities such as power distribution facilities. In some cases, an electric power company performs construction that involves a power outage in order to maintain the equipment. For such construction,
a. Power outage work associated with equipment maintenance (electric pole rebuilding, transformer replacement, etc.) b. Power outage work for insulation measurement (law check) c. There are power outages associated with regular replacement of instruments. At the power company, after confirming the scope of the power outage when planning a work involving a power outage, the person in charge visits all customers who are subject to the power outage and asks for an answer as to whether the work can be performed. . If there are no customers, we will notify you in writing.

  In addition, electric power companies register the background and results of negotiations due to power outages in a database. Then, the electric power company changes or determines the work schedule of the construction based on the data in the database. Furthermore, a system has been proposed in which construction plan information is notified to a communication device such as a PC (personal computer) at a customer's house based on customer information stored in a database. In this system, a reply to determine whether or not it is possible is received from a customer, and a power outage plan is formulated (for example, see Patent Document 1).

JP 2012-123758 A

As described above, when a construction plan involving a power outage occurs, the power company asks whether or not the work can be carried out by visiting all customers. If there are no customers, we will notify you in writing. For this reason, there are the following problems.
a. It is necessary to visit all customers, and labor costs are incurred.
b. When there are no customers, they visit many times.
c. When there are no customers, we provide written notifications depending on the situation, but there are cases where we do not see the documents posted to the post, and there may be inquiries on the day of construction.
d. There are cases of sudden visits for instrument replacement and insulation measurement on the day.
e. When a person in charge of a construction company visits the site, he or she may be misunderstood as a suspicious person and return without being able to complete the work.

  In other words, when working with power outages, power companies often rely on human resources, and it is difficult to provide reliable notifications in writing.

  On the other hand, since the system for notifying construction plan information uses a personal computer, it is necessary to handle personal information such as an e-mail address. For this purpose, it is necessary to manage new personal information including new registration, change, deletion, etc. of e-mail addresses.

  The object of the present invention is to solve the above-mentioned problems, reduce the need to rely on manpower for construction involving a power failure, reliably notify the construction plan, and eliminate the need for management of personal information such as e-mail addresses. To provide a support system.

In order to solve the above-mentioned problem, the invention of claim 1 is installed in a customer's house and checks the amount of power used every predetermined time used in the customer's house, and the power consumption is communicated to the power company.

When the HEMS receives the answer from the terminal, When the smart meter receives the answer from the HEMS, the smart meter sends the answer to the management device via the communication network, and the management device sends a reply to reject the construction plan to the smart meter. When received from the meter, the amount of power used previously received from this smart meter, which is used at the customer's home where this smart meter is installed, and information on the contract details And, based on the information on the power pole, refer to the generator information database to select power generation equipment for power supply by at least one of a consumer unit and a transformer pole unit. It is a support system.

  In the invention of claim 1, the management device of the construction support system transmits the created construction plan to the smart meter via the communication network. When the smart meter receives the construction plan from the management device via the communication network, the smart meter sends the construction plan to the HEMS.

Note that customer homes B and C are representative examples.

  The customer's house B is a residence of a customer who is supplied with electricity from the power distribution system 30 of the power company. The smart meter 41 at the customer's house B is an electronic watt-hour meter managed by an electric power company, and records the amount of power used at the customer's house B every 30 minutes. The smart meter 41 has a communication function. In this embodiment, the smart meter 41 is capable of two-way communication with the management device 11 of the management department A of the power company via the communication network 20 dedicated to the power company. As a result, the smart meter 41 can transmit the recorded power usage amount to the management device 11 of the management department A via the communication network 20 and receive a message sent from the management device 11.

  The smart meter 41 is connected to the HEMS main body 42 so that bidirectional communication is possible. When response information is received from the HEMS main body 42, the address of the own device is added to the response information and transmitted to the management device 11. When receiving a message from the management device 11 toward the HEMS main body 42 of the customer's house B, this message is sent to the HEMS main body 42.

  The HEMS main body 42 manages the energy concerning an apparatus. That is, the HEMS main body 42 manages the amount of energy used by devices installed in the customer's house B and the amount of energy generated in the customer's house B. In this embodiment, the amount of power supplied from the power distribution system 30 through the smart meter 41 to the home appliances 45 and 46 from the distribution board 44 is managed. That is, the HEMS main body 42 has information corresponding to the home appliances 45 and 46, for example, the home appliances are lighting fixtures, by various sensors (not shown) such as illuminance sensors and current sensors attached to the home appliances 45 and 46. Information on the brightness and information on the amount of power consumed when the home appliance is an air conditioner are examined. Moreover, although illustration is abbreviate | omitted, if the solar power generation device is installed in the consumer's house B, the electric energy which this power generation device produces is also managed. Furthermore, depending on the case, the operation state of the home appliances 45 and 46 is also controlled. And the HEMS main body 42 sends the display information showing the electric energy used by the household appliances 45 and 46, operation time, etc. to the HEMS terminal 43. FIG.

  Further, when the HEMS main body 42 receives the information on the power consumption for every 30 minutes at the customer's house B from the smart meter 41, the HEMS main body 42 sends, for example, display information that graphs the power usage for every 30 minutes to the HEMS terminal 43.

  Further, when receiving the response information from the HEMS terminal 43, the HEMS main body 42 sends this input information to the smart meter 41.

  The HEMS terminal 43 is a dedicated terminal for the HEMS main body 42. That is, the HEMS terminal 43 is provided with a touch panel for displaying display information from the HEMS main body 42 and inputting an answer to the display information. When there is a touch panel operation by a customer, the HEMS terminal 43 sends information corresponding to this operation to the HEMS main body 42 as response information.

  The HEMS main body 42, the HEMS terminal 43, the illuminance sensor, the current sensor, and the like as described above constitute the HEMS of the customer's house B.

  On the other hand, the smart meter 51, the HEMS main body 52, and the HEMS terminal 53 installed in the customer's house C are the same as the smart meter 41, the HEMS main body 42, and the HEMS terminal 43 installed in the customer's house B. Description is omitted. Moreover, since the switchboard 54 and the household appliances 55 and 56 of the customer's house C are similar to the switchboard 44 and the household appliances 45 and 46 of the customer's house B, description thereof is omitted.

  The above is the configuration of the smart meters 41 and 51, the HEMS main bodies 42 and 52, and the HEMS terminals 43 and 53 in the construction support system installed in the customer homes B and C. Next, the management device 11 and the storage device 12 installed in the management department A of the power company in the construction support system will be described.

  The storage device 12 of the management department A of the electric power company is a large device for storing information and building a database. In this embodiment, the storage device 12 includes a customer information DB (database) 12A, a smart meter information DB (database) 12B, a system information DB (database) 12C, a utility pole information DB (database) 12D, and a distribution facility information DB ( A database) 12E, a generator information DB (database) 12F, and a power outage construction plan information DB (database) 12G are constructed.

  Customer information DB12A has memorized as customer information information about a consumer (customer) who receives supply of electricity from an electric power company. For example, as shown in FIG. 2, the customer information DB 12A stores a customer number for identifying a customer, a customer name that is the name of the customer, an address of the customer, and a telephone number. In addition, the customer information DB 12A stores the contents of power usage contracted by the consumer with the electric power company, for example, the contents of lamp usage, power usage, contract amperage, and the like. The customer information DB 12A stores a smart meter instrument number for identifying a smart meter installed in a customer's house. The storage device 12 stores such customer information DB 12A for all customers.

  The smart meter information DB 12B stores information on smart meters installed in each customer's house. For example, as shown in FIG. 3, in the smart meter information DB 12B, the customer number for identifying the customer where the smart meter is installed, the customer name which is the name of the customer, and the customer meter are installed in the customer home. A smart meter instrument number for identifying the smart meter is stored. Further, the smart meter information DB 12B stores an address for the smart meter 41 to communicate with the management apparatus 11 of the power company using the dedicated communication network 20 of the power company. Furthermore, the date is stored in the smart meter information DB 12B, and the amount of power used by the customer who has contracted to use the light is stored every 30 minutes, and the customer has a contract to use the power. In the same manner, the amount of power by the power used on the day is stored. The storage device 12 stores such smart meter information DB 12B for each date, and further stores for each customer.

  The system information DB 12C stores information related to the distribution system 30. For example, there is the distribution information of the distribution system shown in FIG. In the power distribution system indicated by this information, utility poles No. 12 to No. 16 are provided in order from the upstream side. In addition, 13M01 and 13M02 utility poles are provided for the 13th utility pole, and 14M01, 14H01, and 14H02 utility poles are provided for the 14th utility pole. Also, 15M01 and 15M02 utility poles are provided for the No.15 utility pole. Furthermore, transformers are installed on the 13M01 utility pole, the 14M01 utility pole, the 14H02 utility pole, the 15M01 utility pole, and the 16 utility pole. In FIG. 4, the one transformer is for electric lamps, and the two transformers are for electric lamps and power.

  In the system information DB 12C of the distribution system 30 in which such power poles, transformers, and the like are installed, as shown in FIG. 5, for example, the demand that draws electricity from the power pole for the power pole number for identifying the power pole When there is a house, a customer number which is an identification number of this consumer is stored. In addition, in the grid information DB 12C, for customers who use electricity, the power usage for every 30 minutes of the smart meter information DB 12B is tabulated using the customer number of each customer as a clue. Thus, the power usage for each utility pole is stored. As for power, the usage amount for each utility pole is stored. In the system information DB 12C, a power distribution facility related to the utility pole, such as a transformer, is stored as the related facility. Furthermore, the load information is stored in the system information DB 12C. In the system information DB 12C, one item has one transformer, and one item has two transformers, and one item has two transformers.

  As shown in FIG. 6, the power pole information DB 12 </ b> D stores information on the front-rear relationship of each power pole in the power distribution system 30. In other words, for example, the number of the power pole on the upstream side is stored as the power pole number (previous) with respect to the corresponding power pole number (related), and the number of the power pole on the downstream side with respect to the corresponding power pole number (related) is the power pole number. It is stored as (after). Thus, the utility pole information DB 12 </ b> D stores the utility pole number (front) and the utility pole number (rear) for the utility pole number (corresponding) of each utility pole of the distribution system 30.

  The power distribution facility information DB 12E stores information related to each facility installed in the power distribution system 30. For example, as shown in FIG. 7, the distribution facility information DB 12 </ b> E stores the date and time of installation of the utility pole and the service life of the utility pole with respect to the utility pole number that is the identification number of the utility pole. In addition, the distribution facility information DB 12E stores whether or not the utility pole is deteriorated or damaged. Furthermore, the distribution facility information DB 12E stores the installation date, the service life, the date and time when the utility pole is scheduled to be rebuilt, which is determined according to the presence or absence of deterioration or damage. In addition, although not shown in FIG. 7, the information, such as the transformer installed in the power distribution system 30, is similarly memorize | stored in power distribution equipment information DB12E. In this case, the telephone pole number of the item name is changed to, for example, a transformer number, and transformer information is stored.

  The generator information DB 12F stores information on generators and generator cars that are installed and used by consumers and transformer poles (electric poles with transformers) at the time of a power failure. The generator is moved by another conveying means, and the generator car can move by itself. In other words, the generator and the generator car are devices for continuing to supply electricity to the customer during a power outage work or the like. For example, as shown in FIG. 8, the generator information DB 12F stores a device number for identifying the generator and the generator car. In addition, the generator information DB 12F stores equipment types representing generators and generator cars. Further, the generator information DB 12F stores the output of the generator or generator car, voltage, current, continuous operation time, and the like. Further, the generator information DB 12F stores whether or not the generator and the generator car are stored in an electric power company and can be used.

  The power failure work plan information DB 12G is a necessary electrical work for the power distribution system 30, and stores a work plan for electrical work involving a power failure. This construction plan is obtained from the customer information DB 12A, the system information DB 12C, and the distribution facility information DB 12E. In the power outage construction plan information DB 12G, a construction number for identifying the construction, a construction content indicating what kind of construction is to be performed, a date and time of the construction are recorded. The power outage construction plan information DB 12G records a construction company that performs this construction, a person in charge of this construction, and contact information when an emergency occurs during this construction.

  As described above, the storage device 12 stores the customer information DB 12A to the power outage construction plan information DB 12G.

  The management terminal 13 is a computer operated by a person in charge of the management department A. The management terminal 13 is connected to the management apparatus 11 so that data can be transmitted to and received from the management apparatus 11. Thereby, the management terminal 13 exchanges various information with the management device 11 and the storage device 12.

  The management device 11 is a computer for managing customers of electric power companies and various facilities. The management device 11 basically reflects information input from the management terminal 13 in each content for the customer information DB 12A, system information DB 12C, utility pole information DB 12D, distribution facility information DB 12E, and generator information DB 12F. The management device 11 reflects the information input from the management terminal 13 for each customer number to date in the smart meter information DB 12B, and the power consumption of the smart meter information DB 12B is transmitted via the communication network 20. Reflect the information from the smart meter you receive.

  The management apparatus 11 is as follows about the power failure construction plan information DB 12G. The management device 11 basically reflects the power outage construction plan information DB 12G with reference to the power distribution facility information DB 12E. Moreover, about the scheduled construction date, the management apparatus 11 checks the electric power usage amount for every hour of the consumer who is affected by the construction accompanied by the power failure from the electric power usage amount of the smart meter information DB 12B. At this time, the management apparatus 11 checks the customers affected by the work involving the power failure with reference to the system information DB 12C and the utility pole information DB 12D based on the work contents of the power failure work plan information DB 12G.

  Based on the smart meter information DB 12B, the management device 11 checks such power usage for each consumer and further checks every day. And the management apparatus 11 determines the scheduled construction date and the content of the construction time of the power outage construction plan information DB 12G from the day when the power usage amount of each consumer is low and the time zone when it is small, and adds the construction number. Regarding the construction company, the construction manager, and the contact information, the management device 11 reflects the information input from the management terminal 13 in the contents of the power outage construction plan information DB 12G.

  In this way, the management apparatus 11 stores information related to the work involving power outage in the power outage work plan information DB 12G. And the management apparatus 11 will display the message for the person in charge showing a construction schedule on the management terminal 13, if it becomes a predetermined period before the construction scheduled date of the power failure construction plan information DB12G. For example, the management apparatus 11 refers to the power outage construction plan information DB 12G and displays on the management terminal 13 by a message that the target of the current power outage construction is related to rebuilding of the No. 13 power pole. Simultaneously, the management apparatus 11 produces | generates the message for consumers reflecting the content of the power failure construction plan information DB12G. This message is for notifying the customer that the construction involving a power failure is to be performed. An example of this message is shown in FIG. This message is generated based on the power outage construction plan information DB 12G. Further, this message is added with a content requesting a customer's answer to the construction that involves a power failure.

  The management apparatus 11 will perform a message transmission process, if the message for consumers is produced | generated. An example of this message transmission process is shown in FIG. The management apparatus 11 checks the customer who is affected by the work involving the current power failure with reference to the system information DB 12C and the utility pole information DB 12D (step S1). For example, if the current construction is the rebuilding of the No. 13 utility pole, the management device 11 refers to the grid information DB 12C and the utility pole information DB 12D and draws electricity from the utility pole arranged downstream from the No. 13 utility pole. Find out who your customers are. The management device 11 refers to the customer information DB 12A for the customer checked in step S1, and checks the smart meter installed in each customer's house (step S2). The management apparatus 11 refers to the smart meter information DB 12B for the smart meter checked in step S2, and checks the address of each smart meter (step S3). The management apparatus 11 transmits a message for consumers to each smart meter using all the addresses checked in step S3 (step S4), and ends the message transmission process.

  When the message transmission process is completed, the management device 11 waits for a reply from the customer about whether construction is possible. When the management device 11 receives response information indicating whether or not construction is possible from the customer's smart meter, the management device 11 creates and updates customer response information reflecting the customer's response regarding the current power outage construction. At this time, if the management apparatus 11 receives an answer that does not require a change or cancellation of the schedule for the work involving the current power failure, for example, as shown in FIG. 12, the answer content of the customer answer information is OK. . Moreover, when the management apparatus 11 receives the reply indicating the change or cancellation of the schedule, that is, for the customer who refuses the current construction, the reply content of the customer reply information is set to NG.

  When the management apparatus 11 obtains answers from all customers and finishes updating the customer answer information, it performs a generator selection process. An example of this generator selection process is shown in FIG. The management device 11 examines the customer whose answer content of the customer reply information is NG (step S21). The management device 11 refers to the customer information DB 12A for the customer checked in step S21, and checks the customer contract details (step S22). In step S22, the management device 11 checks whether the consumer has contracted with the electric light, contracted power, and the contract amperage. Thereafter, the management device 11 refers to the customer information DB 12A for the customer checked in step S21, and checks the smart meter installed in the customer's house (step S23). The management apparatus 11 refers to the smart meter information DB 12B for the smart meter checked in step S22, and checks the maximum amount of power used in the construction time zone with the current power failure (step S24). The management device 11 refers to the generator information DB 12F based on the contract amperage of the contract determined in step S22 and the power consumption of the smart meter checked in step S24, and is currently stored in the power company and used. An appropriate generator is selected from the possible generators (step S25). This is to maintain the power supply to this customer even during work involving power outages.

  In step S <b> 25, the management apparatus 11 selects a generator or a generator car (hereinafter referred to as “power generation equipment”) and determines whether or not the selected power generation equipment can be installed in units of individual consumers or transformer poles. . When the management device 11 selects the power generation equipment for each transformer pole and determines whether or not to install, the management device 11 is based on the size of the contracted amperage checked in step S22 and the actual power consumption checked in step S23. Whether the power generation equipment can be selected from the maximum capacity and the necessary minimum capacity of the power generation equipment obtained and whether or not power can be supplied from the power generation equipment in units of transformers with reference to the grid information DB 12C. judge. Furthermore, the management apparatus 11 determines whether or not the selected power generation equipment can be installed from past construction information (not shown). Many of these consumers who are supplied with electricity in transformer units have contracts that only use electric lights.

  If the management device 11 determines in step S25 that the amount of power used is large and cannot supply power in units of transformers, in order to supply electricity in units of individual consumers, the management device 11 is based on the smart meter information DB 12B. Select appropriate power generation equipment and determine whether it can be installed. Many of these customers who are supplied with electricity in units of consumers have contracts that use both light and power.

  When step S25 ends, the management device 11 reflects the equipment number of the selected generator in the customer response information, updates the generator information DB 12F while using the selected generator (step S25), and selects the generator. The process ends.

  The above is the configuration of the management apparatus 11. Next, the operation of the construction support system according to this embodiment will be described.

  Usually, for example, in the customer's house B, the smart meter 41 records the power usage amount every 30 minutes, and transmits information on each power usage amount to the management apparatus 11 of the electric power company via the communication network 20. When the management device 11 receives the information on the power consumption every 30 minutes from the smart meter 41 of the customer's home B, the management device 11 updates the corresponding smart meter information DB 12B based on the customer number included in this information. Further, the smart meter 41 sends the recorded power usage information to the HEMS main body 42. When the HEMS main body 42 receives the power usage information from the smart meter 41, the HEMS main body 42 generates display information that graphs the power usage for every 30 minutes, for example, and sends this display information to the HEMS terminal 43. When the HEMS terminal 43 receives the display information from the HEMS main body 42, the HEMS terminal 43 displays the graphed power usage amount.

  By the way, in the management department A of the electric power company, the management device 11 generates a message for the customer reflecting the contents of the power outage construction plan information DB 12G when a predetermined period comes before the scheduled construction date with power outage. Thereafter, the management apparatus 11 performs message transmission processing. Thereby, the management apparatus 11 tells a consumer the content of the construction accompanied by a power failure and the content for requesting the customer's answer to the construction to the consumer.

  On the other hand, for example, the smart meter 41 at the customer's house B receives a message from the power company. The smart meter 41 sends this message to the HEMS main body 42 when the address of the message is directed to its own device. When receiving the message, the HEMS main body 42 displays this message on the HEMS terminal 43.

  Thereby, the consumer of the customer's house B reads from the HEMS terminal 43 that there is an electrical work accompanied by a power outage soon. Since the message displayed on the HEMS terminal 43 has a content for requesting whether or not the customer is allowed to perform this construction, the consumer operates the screen of the HEMS terminal 43 and inputs the construction availability. To do. When the permission of construction is input to the HEMS terminal 43, the HEMS terminal 43 sends information input by the operation to the HEMS main body 42 as response information. When receiving response information from the HEMS terminal 43, the HEMS main body 42 sends this response information to the smart meter 41. When the smart meter 41 receives the response information from the HEMS main body 42, the smart meter 41 transmits the response information to the management apparatus 11 via the communication network 20.

  When the management apparatus 11 receives a reply indicating whether construction is possible or not from the smart meter 41 of the customer's house B, the management apparatus 11 creates and updates customer reply information reflecting the customer's reply regarding the current power outage construction. When the management device 11 receives an answer that does not require a change or cancellation of the schedule for the construction involving the current power outage, the response content of the customer response information is set to OK, and an answer indicating the change or cancellation of the schedule is received. In this case, the response content of the customer response information is NG.

  When the management apparatus 11 obtains answers from all customers and finishes updating the customer answer information, it performs a generator selection process. Thereby, the management apparatus 11 determines the electric power supply by a consumer unit or a transformer pillar unit about the consumer whose reply content of customer reply information is NG, in order to maintain the electric power supply with respect to this consumer. Then, an appropriate power generation device is selected, and the generator information DB 12F is updated while the selected power generation device is in use. As a result, the management device 11 selects the power generation equipment in units of consumers or in units of transformer columns for the consumers whose customer response information is NG, that is, for the customers who refused the construction. The power supply is supported, so that the power outage at the customer's house can be prevented on the day of construction.

  Thus, according to this embodiment, it is possible to notify the customer that there is a work involving a power failure by using the smart meter, the HEMS main body, and the HEMS terminal. Similarly, the use of the smart meter, the HEMS main body, and the HEMS terminal can be used to obtain an answer as to whether or not the customer can accept the construction. Thereby, it can reduce that an electric power company relies on a hand at the time of the construction accompanying a power failure, and can notify a construction plan reliably to a consumer.

  In addition, according to this embodiment, for a consumer who does not wish to perform construction in response to a consumer's response to the construction, the management device 11 uses the smart meter information DB 12B, the grid information DB 12C, the utility pole information DB 12D, and the generator information DB 12F. Since the power generation equipment is selected for each consumer or transformer pole and power supply is supported, electricity can be supplied to this consumer on the construction day.

  Moreover, according to this embodiment, the management apparatus 11 transmits that there is a construction accompanied by a power outage, using the power company's dedicated communication network 20. As a result, since the management apparatus 11 uses the communication address given to the smart meter 41, handling of personal information such as an e-mail address used by a consumer can be made unnecessary, such as an e-mail address. Management of new personal information including new registration, change, deletion, etc. can be made unnecessary.

Furthermore, according to this embodiment, a message indicating that there is an electrical work involving a power failure can be displayed in advance on a HEMS terminal connected to the HEMS main body of the customer's house. As a result,
a. All customers need to visit and there are labor costs to visit,
b. If there are no customers, you have visited many times,
c. In the absence of customers, we also provide written notifications depending on the situation, but there are cases where we do not see the documents posted to the post, and there may be inquiries on the day of construction,
d. There are cases of sudden visits for instrument replacement and insulation measurement on the day.
e. When a person in charge of a construction company visits the site, it may be misunderstood as a suspicious person and returned without being able to complete the work.
It is possible to prevent such a problem from occurring.

(Embodiment 2)
In the first embodiment, the management device 11 and the smart meters 41 and 51 use the communication network 20 dedicated to the power company. In this embodiment, the Internet is used as the communication network 20. In this case, an IP address (Internet Protocol address) is used as an address for communication of the smart meters 41 and 51. The effect of this embodiment is the same as that of the first embodiment.
