2. Description of the Related Art Generally, in a power system monitoring and control system having a dual system, the characteristics of a switch, which is a facility of the power system,
Changes to the database defining the characteristics of protective relays and the characteristics of various measuring instruments were performed by switching the standby system to the test mode. Further, after the database is changed, if the changed database is not correct and the database is accessed online, the system may malfunction. Therefore, it is necessary to perform a confirmation test of the changed database in the test system.

[0003]

The above-mentioned conventional method is
In order to perform the confirmation test after changing the database, it is necessary to change the standby system to the test mode.While the confirmation test after changing the database, there is no standby system, so the online system fails. I couldn't back up when stopped due to.

The present invention has been made to solve the above-mentioned problems, and in a standby system, information on switching on / off of a switch which is equipment of a power system, operation information of a protective relay, and various measurement information of the power system. It is possible to input data simulating
Further, another object of the present invention is to provide a power system monitoring and control system capable of performing a confirmation test after changing the database in a standby system by providing a monitoring / control function for testing.

[0005]

In order to achieve the above object, the present invention comprises an information receiving means for receiving test information input from a test information input section simulating actual information and actual data from a power system. The real data extracting means is provided for inputting the rising data collected online from the information receiving means by the information inputting means, and extracting only the real data from the inputted information. A power system monitoring control means for monitoring and controlling the power system based on the data is provided, and the result of the monitoring control is displayed on the actual data display means, and only the test information is output from the information output from the information input means. An electric power system monitoring and control test that provides a test information extraction means to extract and conducts a confirmation test of the database after maintenance based on the data extracted by this means The stage is provided, in which is provided a test data display means for displaying the test results.

[0006]

The information receiving means receives information from the electric power system and inputs this information to the information input means. The actual information extracting means extracts actual data from the input information, further performs the electric power system supervisory control processing on the basis of the extracted data in the electric power system supervisory control actual means, and outputs the result to the actual data display means. indicate.

On the other hand, when the operator inputs the test data from the test information input section, the information receiving means receives the test information and inputs it to the information input means. The test information extraction means extracts test information from the input information, inputs it to the power system monitoring control test means, performs power system monitoring control test processing based on this extracted information, and displays the monitoring control results to the test data display means. indicate.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of an embodiment of a power system supervisory control system according to the present invention. Reference numeral 11 denotes an electric power system monitoring control system, which is an information receiving unit 1 for outputting the actual data from the electric power system 10 and the test information from the test information input unit 2 to the information input unit 3, and an actual information extracting unit for extracting the actual data. Four
And a monitoring control actual means 6 for processing the information extracted by the means 4.
A test information extracting means 5 for extracting the test information, and a supervisory control testing means 8 for processing the information extracted by the means 5.
And actual data display means 7 and test data display means 9
Consists of. In the online system of double system, 3,
4, 6, 7 means work, and in standby system, 3, 5, 8,
7 means work. Reference numerals 1 and 2 are for transmitting data to the dual power system supervisory control system.

FIG. 2 shows a format of output data output to the information input means 3 in the information receiving means 1. The first bit, 0, indicates that the output data is the actual information of the power system. FIG. 3 shows a format of output data output from the information receiving means 1 to the information input means 3 when the test data is input from the test information input section 2. The first 1 in the first bit indicates that the output data is test information. The information input means 3 sends the data input from the information receiving means 1 to the real information extracting means 4 and the test information extracting means 5. In the actual information extraction means 4, if the first bit at the head of the data sent from the information input means 3 is 0, the next succeeding power system data is sent to the power system monitoring and control means 6. If the first 1st bit of the data sent from the information inputting means 3 is 1, the test information extracting means 5 sends the following test data to the power system monitoring control testing means 8. The power system supervisory control actual means 6 processes the data sent from the actual information extraction means 4 and displays the result on the actual data display means 7. The power system supervisory control test means 8 processes the data sent from the test information extraction means 5 and displays it on the test data display means 9.

FIG. 4 is a flow chart showing the processing in the information receiving means 1. FIG. 4 includes steps S1 to S6. In step S1, an information acquisition process from the electric power system is executed. In step S2, step S
The information type 0 is added to the data taken in 1, and the output process is executed. In step S3, the presence / absence of data input from the test information input unit 2 is determined. When data is input, steps S4 to S5 are executed.
In step S4, a process of fetching the test data from the test information input unit 2 is executed. In step S5, information type 1 is added to the test data fetched in step S4, and the transmission process is executed. If no data has been input, step S6 is executed. In step S6, the information receiving means 1 is delayed for a certain period of time and is executed at a constant period (for example, a 10-second period).
