In the figure, reference numeral 1 denotes equipment (for example, a transformer, a bus, a transmission line, etc.) and a switch (for example, Power system equipment such as a circuit breaker or disconnector) and a measuring instrument (for example, an ammeter or a voltmeter), 2 collects information indicating the open / closed state of the switch, a measured value of the measuring instrument, and the like, and a host computer 3 3 is a remote monitoring control device that controls a switch and the like in accordance with a control signal output from the control system, and 3 is a power system change based on information indicating the switching state of the switch collected by the remote monitoring control device 2 and a measurement value of a measuring device. And displays the state of the power system on the man-machine I / F 4, and when a control request for a switch or the like is received from the man-machine I / F 4, the control signal is output from the remote monitoring control device 2. Host computer Data, 4 and displays the state of the power system, a man-machine I / F for receiving a control switch or the like.

FIG. 17 is a block diagram showing a test apparatus of a conventional supervisory control system. In FIG. 17, reference numeral 5 denotes simulation data (test data) of a power system and transmits the simulation data to the host computer 3. A test apparatus, 6 is a simulation data creation unit for creating simulation data by a tester who performs a test of the monitoring control system, 7 is a database for storing simulation data created by the simulation data creation unit 6, and 8 is an accumulation in the database 7. A simulation data generating unit for transmitting the simulation data to the host computer 3; a memory 9 of the host computer 3 for storing the simulation data transmitted from the test apparatus 5; and a simulation data generating unit 9 using the simulation data stored by the memory 9 as an input condition. Processing unit of the host computer 3 for executing various programs and outputting the execution results to the man-machine I / F 4 A.

Next, the operation will be described. When the remote monitoring control device 2 collects information indicating the open / closed state of the switch, the host computer 3 of the monitoring control system executes, for example, a state change processing program or a device state change recording program to record a change in the power system. At the same time, processing such as displaying the recording result on the man-machine I / F 4 is executed. When the remote monitoring control device 2 collects the measurement values and the like of the measuring instrument, for example, it executes an electric quantity calculation program and an electric quantity totalization program to record a change in the electric quantity, and records the recording result as a man-machine I / F4 and the like.

When the host computer 3 of the monitoring control system receives a control request for a switch or the like from the man-machine I / F 4, it outputs a control signal to the remote monitoring control device 2 and sends it to the remote monitoring control device 2. A process for requesting control of a switch or the like is executed. As is clear from the above, the host computer 3 of the monitoring and control system is a device that performs monitoring and control of the power system. You need to make sure that it works properly.

Therefore, conventionally, before actually operating the monitoring and control system (including a case where the configuration of the power system is changed), a tester who performs a test of the monitoring and control system uses simulation data of the test apparatus 5. Simulation data is created using the creation unit 6. Specifically, for example, if 100 switches are installed, information indicating the open / closed state of the 100 switches (on state or off state) is created as simulation data. If 50 measuring instruments such as a meter are installed, the measurement values of the 50 measuring instruments are created as simulation data.

[0007] When the tester creates simulation data using the simulation data creation unit 6, the simulation data is temporarily stored in the database 7 and then stored in the memory 9 of the host computer 3 via the simulation data generation unit 8. The data is transferred, and the host computer 3 executes various processes in accordance with the simulation data as in the actual operation. Then, when the man-machine I / F 4 is operated after the processing of the host computer 3 is completed, the processing result of the host computer 3 is displayed. The tester can determine whether the processing result is appropriate. Then, the quality of the monitoring control system is determined.

[0008] A technique similar to this conventional example is disclosed in Japanese Patent Application Laid-Open No. 7-99741, but the technique disclosed in this publication monitors and controls the state change of all devices constituting the power system. In order to automatically input the information into the system, the information set by the tester using the simulation data generating unit is input to the host computer in the order of registration.

[0009]

Since the test apparatus of the conventional monitoring and control system is configured as described above, if the tester manually sets the simulated data, the validity of the processing result of the monitoring and control system is verified. Although it can be confirmed to some extent, it is necessary only to check whether the switching state of each switch and the measurement result of each measuring instrument can be accurately monitored, and to conduct tests according to the actual operation form of the power system However, there is a problem that the correctness of the processing result of the monitoring and control system cannot be accurately confirmed (for example, when many changes occur due to the occurrence of an accident, the processing of the monitoring and control system It is not possible to confirm the guarantee of time or processing capacity).

First, the default state setting unit 14 searches for a circuit breaker by referring to the equipment information of each device, and sets the open / close state of the circuit breaker to “ON” (step ST1). Specifically, the devices A3, B3, C3, D3, and E3 are searched, and the open / close state of the devices A3, B3, C3, D3, and E3 is set to “ON”.

When the open / close states of all the circuit breakers are set to the "ON state", the default state setting unit 14 searches for a disconnector in an unset state by referring to the equipment information of each device, and disconnects the disconnector. It is determined whether the equipment to which the device belongs is a transmission line or a transformer and the connection position is located on the bus side (steps ST2 to ST5).

FIG. 7 is a flowchart showing a test method of the monitoring control system according to the second embodiment of the present invention.

Next, the operation will be described. As in the first embodiment, the simulation data is stored in the simulation data storage unit 20.
The simulation data is transmitted to the host computer 3 of the monitoring and control system, and the host computer 3 of the monitoring and control system executes various processes according to the simulation data as in the actual operation. If it is necessary to perform a test at the time of occurrence of an accident, first, a tester selects an initial system of a power system to simulate the occurrence of an accident (steps ST11 to ST13). In the second embodiment, a description will be given assuming that the system shown in FIG. 8 is selected as an initial system of the power system.

When the tester selects the initial strain,
The power system shown in FIG. 8 is displayed on a CRT (not shown) on the screen.
Then, an accident occurrence time is set (step ST14). In the example of FIG. 8, the 500 KV instep bus is selected as the accident facility. Then, when the tester sets an accident facility or the like in the power system, the power flow calculation unit 27 executes a power flow calculation on the condition of the switching state of each switch, the type of the accident, and the like, and calculates the amount of electricity immediately after the occurrence of the accident. I do.

Then, when the tester sets an accident facility or the like in the power system, the relay extraction section 24 searches the relay information storage section 23 for protection relays for protecting the accident facility and displays a list on a CRT (not shown) ( Step ST16). Then, when the tester selects one of the protection relays using the relay selection unit 25 (step ST17), the state change unit 26 refers to the information stored in the relay information storage unit 23, and selects the protection relay. Identify the breaker that trips. In the example of FIG. 9, information indicating that the circuit breaker in which the protection relay A trips is the devices A3, B3, C3, D3, and E3 is stored in the relay information storage unit 23.

When the state change unit 26 specifies the circuit breaker at which the protection relay trips, the state change unit 26
A breaker electrically connected to the accident facility is selected (step ST18). For example, when the protection relay A is selected, the circuit breakers that trip the protection relay A are the devices A3, B3, C3, D3, and E3, but the devices B3 and B3.
The circuit breaker of D3 sandwiches B1 and D1 already in the off state between the accident equipment, and thus does not need to change the open / close state of the circuit breakers of the devices B3 and D3 to the off state again. Therefore, A3, C3, and E3 circuit breakers that are electrically connected to the 500 KV line A, which is the accident facility, are selected. When the state change unit 26 selects a circuit breaker having an electrical connection with the accident facility, the state change unit 26 changes the open / close state of the circuit breaker to the “off state” in order to disconnect the accident facility from the power system (step ST19). ).

As described above, when the state change unit 26 changes the open / close state of the circuit breaker to the “off state”, the power flow calculation unit 27
Performs the power flow calculation on the condition of the switching state of each switch (breaker, disconnector) and the like, and calculates the electric quantity of the power system after the elimination of the accident (step ST20). As a result, the switching state of each switch before and after the accident, the electric quantity of the power system, and the like are registered as simulation data in the accident scenario database 28 (step ST21), so that the host computer 3 of the monitoring and control system operates during the actual operation. Similarly to the above, processing at the time of occurrence of an accident can be executed according to the simulation data.

FIG. 10 is a state change list showing simulated data at the time of the occurrence of an accident.
Since the operating time and operating conditions of protection relays and circuit breakers are taken into account, the time from the occurrence of an accident until the circuit breaker actually transitions to the OFF state is set to a time that is compatible with the actual operation mode. . Incidentally, the state change list is a CRT (not shown).
, The tester can check the status change list and can change the status change list.

As is apparent from the above, the second embodiment
According to the present invention, a protection relay that protects an accident facility is searched from the relay information storage unit 23, and a switch that trips the protection relay is specified. Is configured to change the open / closed state of the switch having a connection relation to the off state, so that it is possible to perform a test when an accident occurs in the power system.
