DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a plurality of business establishments for monitoring and controlling a plurality of system facilities of a complicated and large-scale industrial system such as an electric power system, a water supply and sewage system, and the like. The present invention relates to a system simulating apparatus which is applied to a supervisory control system and simulates the power system and the operation of each business establishment, and a storage medium readable by a computer for system simulation.

[0002] The present invention also relates to a system simulation apparatus applied to a system operation training system in which a plurality of training stations for performing operation training such as monitoring and control for a plurality of system facilities of the industrial system are hierarchized. And a storage medium readable by a computer for system simulation.

[0003]

2. Description of the Related Art In recent years, in a monitoring control system for monitoring and controlling a plurality of system facilities constituting an industrial system such as an electric power system and a water supply and sewage system, recently, the area of the system facilities to be monitored and controlled has been widened and expanded. The scale is increasing,
There is a demand for the construction of a system that supports such a wide area and a large scale.

[0004] From such a background, in order to monitor and control an enormous number of system facilities distributed over a wide area, the supervisory control system has a hierarchical and hierarchical structure in accordance with its role. It is configured to be distributed (divided) in regions.

For example, in a power system monitoring and control system for monitoring and controlling a power system, as shown in FIG. 24, a power system P (for example, a wide-area power network of electric stations 150A to 150D) has a supply and demand monitoring control and a system monitoring control. , And equipment monitoring control, and an office (power supply station, electric station, etc.) is provided for each of these control layers to perform monitoring control of the power system P.

[0006] The control hierarchy of the electric power system P is generally divided according to supervisory control duties, voltage classes, and the like, and offices having the same control hierarchy are distributed and located in regions.

That is, as shown in FIG. 24, a plurality of power plants and a plurality of substations (hereinafter collectively referred to as electric stations) 150 as the lowest control hierarchy (equipment monitoring control hierarchy).
A to 150D are distributed, and the substations 150A and 150D
A power supply station 151A that supervises and controls OB and a power station that supervises and controls electric stations 150C and 150D.
1B are distributed. Further, a central power supply station 152 is arranged as a business office of the highest level supply and demand monitoring control hierarchy, and each of these business offices (the central power supply station 152 and the power supply station 15).
1A-151B, electrical stations 150A-150D) are interconnected via a wide area network (WAN) 153.

In the monitoring and control system configured as described above, each business establishment fetches information related to the system equipment under the control of the other business establishment from another business establishment via a wide area network, and acquires the acquired system equipment information. Can be processed and used in a form required by each of the establishments, and the monitoring control (the monitoring control for other establishments) linked to the electric power system among the plurality of establishments described above. And backup).

Each of the above-mentioned offices is composed of one or a plurality of computers, and an operator operates the computer at each office to perform a monitoring control operation.

[0010] Therefore, in order to promptly and accurately perform the monitoring and control of the power system, it is essential that the operator perform the operation related to the monitoring and control promptly and accurately at each business site.

Therefore, conventionally, by using a training target computer that simulates the response of a computer at a predetermined business establishment and a system simulating device that simulates the response of a power system, the system operator is not trained in the case of training. A trainee (hereinafter, referred to as a trainee) can perform operation training related to monitoring and control via the training target computer (see, for example, Japanese Patent Application Laid-Open No. 5-515083).

According to this training system, the information obtained by the trainee monitoring and controlling the computer to be trained is sent to the system simulating device, and the system simulating device simulates the actual response of the power system in accordance with the sent information. The response data is transmitted to the computer to be trained. As a result, the training of trainee operation is performed by creating a situation in which the trainee is operating the actual power system.

The conventional system simulation device used in the above-mentioned training system and the like has a function of simulating the response of the power system to a certain computer to be trained.

That is, the conventional system simulation apparatus mainly includes a state change indicating the operation state of each system equipment constituting the power system irrespective of which office (computer) the computer to be trained simulates. Information (SV information) was simulated, and the simulated information was transmitted to the training target computer in a unique form.

In the conventional system simulation device, when simulating TM information (telemeter value) indicating the state value of each system equipment, a telemeter value based on the actual configuration of the power system is not used. A value that is arbitrarily input by a trainee (trainer) or the like and that corresponds to a small area of the system range such as around a power plant is used.

On the other hand, since the above-mentioned monitoring control objects are constantly expanding and expanding, the number of business establishments corresponding to newly introduced system equipment is increased. In addition, in accordance with such expansion of a business establishment or integration of a plurality of business establishments, the range of system equipment to be monitored and controlled by each business establishment is changed between the business establishments.

In the above-mentioned monitoring and control system, when an extension of a business establishment or a change in the jurisdiction of the system equipment of each business establishment is performed, such an extension establishment or a business establishment whose jurisdiction is changed (hereinafter referred to as a changed establishment) Before actually operating the monitoring and control system as the above-mentioned monitoring and control system, it is important to perform an operation test of the monitoring and control system in accordance with the addition or change of the offices in order to improve the reliability of the system.

It is considered that the operation test accompanying the addition / change of the office is also performed by using the above-described conventional system simulator.

[0019]

As described above, a plurality of establishments cooperate and utilize information on all system facilities regardless of whether they are subject to jurisdiction or not. In order to perform the monitoring control described above, for example, it is necessary to convert the form of information according to each business office so that the system equipment information can be used in each business office even between business offices having different control layers.

For example, in order to use system equipment information of a business establishment (for example, an electric power plant) whose control hierarchy is lower than that of a power supply plant on the side of a business establishment (for example, a power supply plant) of an upper hierarchy, it is handled at an electric power plant. The system equipment information such as power generation facilities and substation facilities must be reduced and abstracted, and the reduced system equipment information must be sent to a power supply station.

Therefore, a monitoring and control system (hereinafter also referred to as a cooperative monitoring and control system) that performs monitoring and control operations in cooperation with each other by using information on all the system equipment constituting such a power system in cooperation with each other. In order to conduct an operation test of the monitoring and control system associated with the addition or change of offices, and an operation training for a system operation training system corresponding to the cooperative monitoring and control system (hereinafter referred to as a cooperative system operation training system) It is necessary to perform a form conversion of the information including the reduced data.

However, the conventional system simulation device transmits the simulation information in a unique form and cannot perform the form conversion of the information including the contraction. Even if an operation test accompanying the extension / change of the monitoring and control system to an office or an operation training for a cooperative system operation training system is conducted, the above operation test and operation training are conducted on a business unit basis (training site unit). It was difficult to conduct a test (operation training). For this reason, the reliability of the cooperative monitoring and control system is reduced,
In addition, there have been problems such as the ability of the monitoring operator (trainee) to be insufficiently improved.

Further, the conventional system simulation device performs TM information simulation using a value related to local system equipment arbitrarily input by a trainer or the like, instead of a telemeter value based on the actual system configuration of the power system. Because of this, the operation test for the cooperative monitoring and control system that uses information on all the system equipment that composes the power system in cooperation with each other and the operation training for the expansion / change of the office and the operation training for the cooperative system operation training system It was insufficient, and there was a risk that the operation test efficiency and operation training efficiency would be deteriorated.

Further, in order to conduct an operation test (operation training for the cooperative system operation training system) associated with the establishment or change of the business establishment of the cooperative monitoring and control system, the additional
It is also very important to test (train) whether the information handled at the changed office (trained office) is accurately converted and transmitted to another office (other trained computer). In order to perform the test (training), it is necessary to simulate not only the simulation of the power system but also the operation of the extension / change establishment (the training target establishment) itself.

However, the conventional system simulation device only has a function of simulating each system equipment constituting the power system, and cannot simulate the response of the business establishment (training school). It was not sufficient to conduct operation tests for the extension and change of the monitoring and control system and operation training for the cooperative system operation training system.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to obtain a telemeter value corresponding to a tidal current value of an actual power system configuration based on information related to power system equipment. By providing a system simulation device that has a function and a function to perform form conversion processing of information including contraction for simulation information including this telemeter value, it is possible to add or change offices in a cooperative monitoring control system It is an object of the present invention to improve the reliability of the cooperative monitoring and control system and the capacity of the trainee by performing the operation test and the operation training for the cooperative system operation training system very efficiently and effectively.

Another object of the present invention is to provide a system simulation apparatus capable of simulating the operation of an extension / change office or a training target computer itself by using the above-mentioned information form conversion processing function including contraction. Provides a dramatic improvement in the quality and effectiveness of the operation test of the cooperative monitoring and control system (operation training of the cooperative system operation training system) itself by simulating the response of a business establishment (training site) that could not be done conventionally. To improve.

Is different, and is abstracted as it goes to the upper hierarchy, so that the form of information such as a telemeter value and SV data is converted from the system simulation device 3 to the destination office into a mode corresponding to the destination office. This is a process that enables information cooperation between the system simulation device 3 and each business office.

In the above-described form conversion, in particular, abstracting information from lower-level attributes to higher-level attributes is called contraction.

For example, when the system simulation device 3 is an extension substation 7A
When transmitting the telemeter values of a plurality of system facilities to be monitored and controlled to the extension substation 7A, the form conversion means 45
Sends the telemeter values of a plurality of system equipment to the telemeter value transmitting means 46 in the form (abstraction level) as it is.
On the other hand, the system simulation device 3 changes the telemeter values of a plurality of system facilities to be monitored and controlled by the additional substation 7A.
If the control hierarchy is to be transmitted to a higher-ranking business establishment (the power supply station 6 or the central power supply station 5), the telemeter values of the plurality of system facilities are higher-level attribute values such as their average, sum, and representative value. (For example, an average value of all the telemeter values) and transmits it to the telemeter value transmitting means 46.

For example, when the system simulation device 3 transmits SV data of a plurality of system facilities to be monitored and controlled by the extension substation 7A to the extension substation 7A, the form conversion means 4
5 transmits the SV data of a plurality of system facilities as they are (at the abstraction level) to the additional substation 7A via the state change information transmitting means described later. On the other hand, the system simulation apparatus 3 is configured to monitor and control the S
When transmitting the V data to a business establishment (power supply station 6 or central power supply station 5) whose control hierarchy is higher than the extension substation 7A, logical operation values (for example, logical product, The value is converted to an attribute value of a higher level such as a logical sum and transmitted to the status change information transmitting means 50.

The form conversion means 45 stores system information (equipment information and connection information) relating to a plurality of system equipment to be monitored and controlled by the additional substation 7A in the equipment information database 40a.
The connection information is read out from the connection information database 41a and sent to the extension substation 7A as it is, and the upper-level offices such as the power supply station 6 and the central power supply station 5 are operated (opened / closed) by, for example, the lower-level system information. The state and the connection state are tracked and reduced to higher-level system information, and the reduced higher-level system information is sent to a higher-level business establishment.

On the other hand, the system simulation device 3 includes a scenario file F in which information indicating the accident or failure of the transmission path and the status change of the system equipment to be monitored and controlled by the additional substation 7A according to the system operation is stored in advance. Is created in advance and held in the scenario file holding unit 55a, the scenario file F is read out from the scenario file holding unit 55a at a predetermined timing and analyzed, and the operation state of the system equipment corresponding to the analysis result is set as an operation command. A scenario file analysis / transmission unit 55 for transmitting to the reception unit 47 is provided.

For example, the scenario file holding unit 55a
Are, as shown in FIG. 7, a plurality of scenario files (FIG. 7).
Holds three accident scenario files F1 to F3). In each of the accident scenario files F1 to F3, the name of the establishment that changes state (in the case of the simulation of the state of the extension substation 7A, the name of the extension substation 7A), the name of the system equipment that changes state,
And its state of change (in the case of a trip of a circuit breaker or disconnector → open, in the case of bus power failure → bus voltage: 0, frequency: 0,
Load: 0, etc.) are stored in association with each other.

At this time, the receiving means 47 receives an operation command for system equipment based on the sent scenario file. Hereinafter, the SV data based on the state change of the system equipment corresponding to the scenario file is processed by the operation state setting means 48, the form conversion means 45, and the state change information transmitting means 50 in the same manner as the operation command from the destination office. The data is transmitted to the destination office in a form corresponding to the destination office.

On the other hand, in response to the actual operation command transmitted from the destination office or the operation command based on the scenario file, the operation state setting means 48 processes the operation command stored in the equipment information database 40a. When the system equipment changes, the node / branch information generating means 42
Generates node / branch information based on the equipment information and the connection information after the status change, and thereafter generates the status by the above-described processing of the power flow calculation means 43, the conversion means 44, the form conversion means 45, and the telemeter value transmission means 46. The telemeter value to be monitored and controlled by the extension substation 7A corresponding to the changed node / branch information is transmitted to the destination office.

Then, the system simulation device 3 generates a power flow cross-sectional view showing a systematic relation between nodes and branches based on the node / branch information generated by the node / branch information generating means 42. 56
And a display means 57 for displaying the tidal current cross section created by the tidal current cross section creating means 56.

The processing blocks of the system simulation device 3 described above correspond to the processing of the CPU 25, the I / F 26, the input unit 27, the memory 28, and the display device 28 shown in FIG. CPU2 based
5, cooperative processing of the I / F 26, the input unit 27, and the display device 28).

Next, regarding the overall operation of the system simulation device 3, in particular, (1) generation and transmission simulation of telemeter values of system equipment to be monitored and controlled by the additional substation 7A, (2)
Response simulation corresponding to an operation command sent from the destination office to the system equipment, and (3) automatic state change simulation of the system equipment using a scenario file will be described.

(1) Telemeter value generation and transmission simulation [A] In the case of performing an operation confirmation test of the extension substation 7A For example, the system equipment of the extension substation 7A is simulated and the telemeter value is transmitted to the extension substation 7A. Accordingly, when performing an operation check test based on the telemeter value transmission of the extension substation 7A that is not connected to the wide area network 9, the system facility information management unit 40 and the system configuration information management unit 41 include the system simulation device 3 A facility information database 40a and a connection information database 41a based on the facility information and the connection information acquired by the processing of the receiving means 47 are respectively created. Further, an extension substation 7A is managed as a destination business office of the form conversion means 45.

At this time, the node / branch information generating means 42 performs the node / branch information generating process shown in FIG.

That is, the node / branch information generating means 42 executes the node / branch contraction processing for the generator nodes and the branches by generating the power generation facilities controlled by one power plant extracted from the plurality of power plants 8. Equipment information in the equipment information database 40a of the system equipment information management means 40
From the connection information database 41a of the system configuration information management means 41. Further, the node / branch information generation unit 42 acquires information on the power transmission equipment connected to the power generation equipment from the equipment information database 40a, and acquires the connection relation of the power transmission equipment from the connection information database 41a. Here, FIG. 9 shows a configuration example of a power generation facility of the power plant 8 configured from the acquired facility information and connection information.

At this time, the node / branch information generating means 42 determines the connection relation of the connection between the power generation equipment and the power transmission equipment (each transmission line) recognized from the acquired equipment information and connection information, and the circuit breaker and disconnector. Based on the open / closed state of the power generation equipment, the connection state from each power transmission line of the power transmission equipment to the generator is traced, and the power generation equipment to which the connection from each power transmission line is established is collectively replaced with one node N ( Step S
1).

For example, in FIG. 9, power generation facilities K1 to K4 branched from two transmission lines into four are replaced with four nodes N (1) to N (4), respectively.

Next, the node / branch information generating means 42
Eliminates duplication when duplicated nodes N are generated by the processing in step S1 (duplicated nodes N (1), N
(2) → one node N1, duplicated node N (3),
N (4) → one node N2), and the transmission lines connected to the nodes N1 and N2 are replaced with branches B1 and B2.

As a result, for example, the power generation equipment of the power plant 8 shown in FIG. 9 is replaced with the nodes N1 and N2 and the branches B1 and B2 shown in FIG.

Then, the node / branch information generating means 4
2 sets TM information including the TM value in the replaced node / branch information (step S2).

The node / branch information generation means 42 converts all the power generation facilities / power transmission facilities into node / branch information by performing the processing of steps S1 and S2 for all the power generation facilities at all the power plants. Then, the power supply amount of the power system 1 is set.

Subsequently, the node / branch information generating means 42
, As node / branch contraction processing to bus nodes and branches, extracts equipment information of substations managed by one substation extracted from a plurality of substations 7. The connection information of the substation is obtained from the connection information database 41a of the system configuration information management means 41, obtained from the database 40a. Further, the node / branch information generating means 42 stores information on the power transmission equipment connected to the substation equipment in the equipment information database 40.
a from the connection information database 41a. Here, FIG. 11 shows a configuration example of a substation facility of the substation 7 configured from the acquired facility information and connection information.

At this time, the node / branch information generating means 42 determines the connection relation of the connection between the substation equipment and the transmission equipment (each transmission line) recognized from the acquired equipment information and connection information, and the circuit breaker and disconnector. Based on the open / closed state of the substation equipment, etc., the buses of the same voltage class with which connection is established from each bus of the substation equipment are traced, and the traced buses are collectively replaced with one node N (step S3).

For example, in FIG. 11, buses (bus facilities) bu1 to bu3 of the same voltage class to which connection has been established are replaced with three nodes N10 to N12, respectively.

Next, the node / branch information generating means 42
When there is an overlapped node N due to the processing in step S3, the overlap is eliminated (no overlapped node in FIG. 11), and the transmission lines and transformers connected to the nodes N10 to N12 are connected to the branches B (10) to Replace with B (14).

Note that, depending on the power flow calculation method, the branches having the same node at the start point and the end point (for example, the branches B (10) and B (11), the branch B (12) and the branch B (13)) may be duplicated. In this case, the duplicated branches B (10) and B (11) are assigned to one branch B10, and the duplicated branches B (12) and B (13) are assigned to one branch. B12.

As a result, for example, the substation 7 shown in FIG.
Are replaced with nodes N10 to N12 and branches B10 and B12 shown in FIG.

Then, the node / branch information generating means 4
2 sets TM information including a TM value in the replaced node / branch information (step S4).

The node / branch information generation means 42 converts all the substation facilities and transmission facilities into node / branch information by performing the processing of steps S3 to S4 for all substation facilities at all substations. Then, the power demand of the power system 1 is set, and the node / branch information generation processing ends.

When the node / branch information is generated in this way, the tidal flow calculating means 43 uses the generated tidal / branch information to determine the tidal flow value (tidal flow rate) of each branch, that is, the entire power system 1. A tidal current value is calculated.

At this time, the conversion means 44 performs the conversion processing shown in FIG. 13 based on the calculated flow value of each branch.

That is, the conversion means 44 converts the calculated power flow value of each branch into the node / branch information generation means 4
Each branch is divided according to the number of system equipment replaced in the processing of steps S2 and S4 of step 2 (step S10).

For example, if the equipment attribute of a certain branch after the calculation of the power flow is a transformer, the power flow value of that branch is divided by the number of transformers replaced to convert it into one branch. When the equipment attribute of a branch is a transmission line, the power flow value of the branch is divided by the number of replaced transmission lines to convert the branch into one branch.

Then, the conversion means 44 sets each power flow value obtained by dividing each branch as a telemeter value of each system equipment replaced as each branch (step S11). As a result, the power flow value (telemeter value) of the system equipment of the power system 1 including the power flow value of the system equipment of the additional substation 7A is obtained.

The telemeter value of each system equipment obtained by the conversion processing of the conversion means 44 is stored as TM information in the equipment information database 40a, and then sent to the form conversion means 45.

In the form conversion means 45, the processing shown in FIG. 14 is performed based on the sent telemeter value of each system equipment.

That is, the form conversion means 45 calculates the telemeter value of the system equipment corresponding to the business office (extension substation 7A) managed as the destination business office from the transmitted telemeter value of each system equipment of the power system 1. (Step S
20).

Next, the form conversion means 45 determines whether or not the destination office to which the telemeter value of the extracted system equipment is transmitted is an upper-tier office (step S21). Now, since the destination office is the extension substation 7A, the result of the determination in step S21 is NO, and the form conversion means 45 sends the extracted telemeter value of the system equipment as it is via the telemeter value transmission means 46. It is transmitted to the extension substation 7A. The telemeter value transmitting means 46 transmits the telemeter value to the extension substation 7A at regular intervals (step S22).

As a result, a telemeter value of the system equipment to be monitored and controlled by the additional substation 7A is generated from the power flow value created based on the equipment information and connection information on all the system equipment constituting the power system 1. And the generated telemeter value can be transmitted to the additional substation 7A.

That is, in the above-described operation confirmation test regarding the transmission of the telemeter value of the extension substation 7A, the telemetry value based on the actual power system 1 is used without using the arbitrarily set telemeter value relating to the local system equipment. Since the above-described operation check test can be performed using the telemeter value, the operation check test of the extension substation 7A can be effectively performed.

Further, in the telemeter value generation and transmission simulation of the present embodiment, the electric characteristics of the power system 1 can be displayed on the display device 29 as a power flow sectional view.

That is, the tidal current cross section creating means 56 applies the node / branch information (node, branch) generated by the node / branch information generating means 42 to the geographical position information and the display screen of the display device 29. By adding position information on the screen of the display device 29 on the basis of the relative information and the like, a tide cross section (screen data representing the tide cross section) is created (FIG. 15; step S30). The display means 57 outputs and displays the created tidal current sectional view on the display device 29 (step S31).

As a result, the display screen of the display device 29
As shown in FIG. 16, a power flow cross-sectional view F representing the system configuration of the power system 1 by nodes N and branches B is displayed.

Next, the power flow sectional view creating means 56 determines whether or not the configuration of the node / branch has been changed by the processing of the node / branch information generating means 42 (step S32). And simulation of a state change by a scenario file is executed, and the new node
When the branch information is generated, the determination in step S32 becomes YES, and the tide cross section creating unit 56 rearranges the nodes and branches previously configured as the tide cross section based on the newly generated node / branch information. And the node
A tidal current sectional view corresponding to the branch configuration change is created (step S33). Then, the display means 57 outputs and displays the created tidal current sectional view on the display device 29 (step S34).

As a result, the power flow sectional view F displayed on the display screen of the display device 29 shows that the node / branch configuration changes in response to the change in the system configuration of the power system 1. Changes can be displayed in real time.

That is, in the operation confirmation test relating to the transmission of the telemeter value of the extension substation 7A of the present embodiment, it cannot be displayed in the conventional operation confirmation test using the numerical value relating to the arbitrarily set local system equipment. A power flow sectional view showing the system configuration of the power system 1 can be easily displayed in real time while corresponding to a change in the system configuration of the power system 1.

[B] When an operation test (operation test related to telemeter value transmission) of the extension substation 7A is performed. Telemeter of the system equipment which is an object of monitoring and control of the extension substation 7A generated by the operation of the system simulation device 3 described above. By transmitting the value to an upper-level business establishment whose control hierarchy is higher than that of the extension substation 7A, an operation test relating to the telemeter value transmission of the extension substation 7A can be simulated by simulating the telemeter value generation and transmission operations. it can.

For example, when, for example, the central power supply point 5 is managed as the destination business office of the form conversion unit 45, the result of the determination in step S21 of the form conversion unit 45 is YES.
And the form conversion means 45 outputs the extracted extension substation 7A
The telemeter value of the system equipment to be monitored and controlled is converted into a form (abstraction degree) handled by the upper-level business establishment (central power supply station 5) and reduced, and the reduced telemeter value is telemeter value transmitting means 46. Via the wide area network 9 to the power supply station 6 at regular intervals (step S23),
The process ends.

For example, when transmitting a telemeter value of a transformer as a system facility, it is assumed that the transmission
If the transformer of the transformer is under the jurisdiction (monitoring control), the central power supply station 5 only needs to monitor and control the passing power flow to the additional substation 7A. (For example, an average value or a sum value), and the abstracted telemeter value is transmitted to the central power supply station 5 via the wide area network 9.

As described above, when the upper-tier business establishment is the central power supply station 5, the central power supply station 5 performs a supply and demand monitoring control operation, so that the telemeter value relating to the substation equipment is reduced and transmitted. On the other hand, if the upper-level business establishment is the power supply station 6, the power supply station 6 performs system monitoring and control work.
Telemeter values related to the power generation equipment are reduced and transmitted.

As a result, the central power station 5 receives the telemeter value transmitted via the wide area network 9 and performs an operation test on the transmission of the telemeter value of the extension substation 7A according to the received telemeter value. It is.

That is, in the present embodiment, the system simulation device 3 can simulate the telemeter value generation operation, the telemeter value reduction operation, and the reduced telemeter value transmission operation of the extension substation 7A. Thus, an operation test that could not be performed, that is, an operation test for confirming whether or not the telemeter value obtained at the additional substation 7A is accurately reduced and transmitted to an upper-layer business establishment can be easily performed.

Therefore, an operation test (telemeter value transmission test) accompanying the extension of the monitoring and control system 2 can be performed very effectively, and the reliability of the monitoring and control system 2 can be improved.

(2) Response simulation corresponding to operation command [A] Operation confirmation test of extension substation 7A (operation command transmission /
(Response data reception test) Extension substation 7A as the destination business office of form conversion means 45
Is managed, when an operation command (for example, an open / close command for a circuit breaker, etc.) of the system equipment to be monitored and controlled by the additional substation 7A is transmitted to the system simulation device 3 from the additional substation 7A. The transmitted operation command is received by the receiving unit 47.
(FIG. 17; step S40).

At this time, the operation state setting means 48 searches the equipment information database 40a of the system equipment information management means 40 based on the received operation command, and sets the operation state of the system equipment corresponding to the operation instruction to the operation instruction. The state is changed accordingly (step S41).

Next, the operation state setting means 48 adds the operation state information (SV data) of the set system equipment via the state change information transmission means 50 in a form corresponding to the hierarchy of the expansion substation 7A from which the operation command is transmitted. The transmission is made to the substation 7A (step S42). In the process of step S42, since the establishment of the operation command transmission source is not an upper-tier establishment,
The V data is transmitted as it is to the additional substation 7A.

On the other hand, node / branch information generating means 42
The processing of steps S1 to S4 shown in FIG. 8 is performed based on the equipment information and the connection information after the status change to generate the node / branch information after the status change, and the power flow calculation means described above 43 arithmetic processing and conversion means 4
4 (steps S10 to S11), the form conversion processing of the form conversion means 45 (steps S20 to S22), and the telemeter value transmission processing of the telemeter value transmission means 46, the system configuration of the power system 1 after the state change. Is transmitted to the additional substation 7A (step S43), and the process is terminated.

As a result, in the extension substation 7A, it is automatically determined whether or not the transmitted SV data matches the content of the transmitted operation command, and the transmission of the operation command of the extension substation 7A is performed accurately. It is automatically checked whether the operation has been performed. Further, the power system 1 changed in response to the operation command
The telemeter value of the monitoring and control target system equipment based on the tidal current value is received and provided for display, for example.

As described above, according to the system simulation device 3 of the present embodiment, in addition to the state change confirmation test corresponding to the operation command, the telemeter based on the change in the system configuration of the power system 1 corresponding to the state change. Since the value can be transmitted to the extension substation 7A, the extension substation 7A can easily grasp the change in the telemeter value corresponding to the transmitted operation command, and transmit the operation command of the extension substation 7A. In addition, the efficiency of the response data reception test can be increased.

[B] When an operation test (operation command reception / responsive data transmission test) of the extension substation 7A is performed An upper-level business office (for example, the power supply station 6) is managed as a destination business office of the form conversion unit 45. In this state, when an operation command (for example, a command to open or close a circuit breaker) of the system equipment to be monitored and controlled by the extension substation 7A is transmitted from the power supply station 6 to the system simulation device 3, the transmitted operation command is It is received by the receiving means 47 (step S40), and thereafter, the processing of step S41 is performed by the operation state setting means 48, and the state of the system equipment corresponding to the operation command is changed.

Next, the operation state setting means 48 reduces the set operation state information (SV data) of the system equipment to a form (abstraction degree) corresponding to the hierarchy of the upper hierarchy establishment (power supply station 6) from which the operation command was transmitted. About.

For example, when transmitting SV data relating to a plurality of circuit breakers of a power generation facility of a power plant, the power supply station 6 only needs to monitor and control the entire output value of the power plant. Is not transmitted to the power supply station 6 (in this specification, the non-transmission is also included in the contraction).

On the other hand, when the upper-level business establishment of the operation command transmission source is the central power supply station 5, the form conversion means 45 transmits the plurality of SV data to the central power supply station 5, respectively.

As described above, when the upper-tier business establishment is the central power supply station 5, the central power supply station 5 performs the supply and demand monitoring control operation, so that the SV data related to the substation equipment is reduced. On the other hand, if the upper-level business establishment is the power supply station 6,
Since the power supply station 6 performs the system monitoring and control work, the SV data related to the power generation equipment is reduced.

The node / branch information generating means 4
By the processing of step 2, the processing of steps S1 to S4 shown in FIG. 8 is performed based on the equipment information and the connection information after the state change to generate the changed node / branch information. 43 arithmetic processing and conversion means 4
4 (steps S10 to S11), the reduction processing of the form conversion means 45 (steps S20, S21 and S23), and the telemeter value transmission processing of the telemeter value transmission means 46, the power system 1 after the state change. The reduced telemeter value of the system equipment to be monitored and controlled by the additional substation 7A according to the system configuration is transmitted via the wide area network 9 to the higher-level business establishment (power supply station 6) (step S43), and the processing is performed. To end.

As a result, at the power supply station 6, it is automatically determined whether or not the transmitted SV data matches the content of the operation command, and whether the operation command of the power supply station 6 was correctly transmitted. Is automatically confirmed, and the telemeter value of the monitored and controlled system equipment based on the power flow value of the power system 1 changed in response to the transmitted operation command is reduced in accordance with the form of the power supply station 6. It is received in a state where it is in a state where it is provided, for example, for display.

That is, according to the system simulation device 3 of the present embodiment, even when the operation test (operation command reception / responsive data transmission test) of the extension substation 7A is performed, the state change confirmation test corresponding to the operation command is performed. In addition, since the telemeter value based on the change in the system configuration of the power system 1 according to the change can be reduced and transmitted to the upper-level business establishment (power supply station 6), the upper-level business establishment (power supply In the place 6), the change of the telemeter value corresponding to the transmitted operation command can be easily grasped, and the efficiency of the operation command transmission and the response data reception test of the upper hierarchy office can be increased.

(3) Automatic Simulation of State Change Using Scenario File [A] Case where Operation Confirmation Test of Extension Substation 7A is Performed The extension substation 7A is used as the destination business office of the form conversion means 45.
Is managed, the scenario analysis / transmission means 55 sends the scenario file holding unit 5 at a predetermined timing.
For example, the accident scenario file F1 is read from 5a,
The accident scenario file F1 is analyzed, and an operation command for tripping the system equipment (the circuit breaker 1 and the circuit breaker 2) of the additional substation 7A is output (FIG. 18; step 50).

After the output operation command is received by the receiving means 47, it is sent to the operation state setting means. The operation state setting means 48 includes steps S41 and S41.
By performing the same processing as in step 42, the operation state of the system equipment (circuit breaker 1 and circuit breaker 2) corresponding to the operation command is changed according to the operation command, and the changed SV data is added to the additional substation 7A. (Step S51).

In the following, similar to the response simulation corresponding to the operation command of the above (2), the telemeter value of the system equipment to be monitored and controlled by the additional substation 7A according to the system configuration of the power system 1 after the status change is Transmission to the extension substation 7A (step S5
2), end the process.

As a result, at the additional substation 7A, the SV data associated with the state change of the monitored and controlled system equipment automatically generated in accordance with the analysis processing of the scenario F1 and the power system 1 of the power system 1 changed corresponding to the state change. A telemeter value of the monitored and controlled system equipment based on the power flow value is received.

That is, according to the system simulation device 3 of this embodiment, the state of the system equipment to be monitored and controlled by the extension substation 7A can be changed without the system operator of the extension substation 7A inputting an operation command. Can be automatically created based on the scenario file, and the SV data and the telemeter value associated with the above-mentioned state change can be transmitted to the expansion substation 7A, respectively. The operation confirmation test efficiency of the substation 7A can be increased.

[B] When an operation test of the extension substation 7A is performed An operation test of the extension substation 7A is managed by the upper-level office (the central power station 5 and the power station 6 as the destination office of the form conversion means 45). ), The above [A]
In the operation confirmation test of the additional substation 7A, the contraction processing is added in the processing of steps S51 and S52 of the system simulating apparatus 3, and otherwise the same as the processing of steps S50 to S52 of the system simulating apparatus 3 described above. is there.

That is, the operating state setting means 48 performs the same processing as in step S41 and step S42, thereby converting the SV data changed in response to the operation command to the upper-level business establishment (central power supply station 5, power supply The transmission is reduced according to the control layer of the place 6). In addition, by the processing of the node / branch generation means 42 and the like, the reduced telemeter value of the system equipment to be monitored and controlled by the additional substation 7A according to the system configuration of the power system 1 after the status change is transmitted via the wide area network 9. To the upper-tier business establishments (central power supply station 5, power supply station 6).

That is, according to the system simulation device 3 of the present embodiment, the state of the system equipment to be monitored and controlled by the upper-layer business establishment can be changed without the system operator of the upper-level business establishment inputting an operation command. Can be automatically created based on the scenario file, and the SV data and the telemeter value associated with the above-mentioned status change can be transmitted to the upper-level business establishments. The operation test efficiency of the place 7A can be increased.

It should be noted that (1) described above in the present embodiment.
In each of the tests (3) to (3), the form conversion unit 45 and the telemeter value transmission unit 46 perform the processing in step S22 in FIG.
Alternatively, by the processing in step S23, the telemeter value is transmitted, for example, at a fixed cycle to the destination / source business office (the additional substation 7
A or the upper-level office), but the present invention is not limited to this. For example, as shown in FIG. 19, the telemeter value transmitting means 46 is a monitoring and control target of the additional substation 7A. It is also possible to transmit the telemeter value of the system equipment to the extension substation 7A or the upper-level business establishment while perturbing the telemetry value (step S55). As described above, by adding perturbation to the telemeter value and transmitting the perturbation to the additional substation 7A or the upper-level business establishment, it is possible to simulate the generation and transmission of the telemeter value reflecting the actual fluctuation of the power system 1.

The above-described process of perturbing and transmitting the telemeter value can be executed other than the process of the telemeter value transmitting means 46.
