Problems solved by technology

Without an information aggregation and sharing platform, it will inevitably result in a large number of repeated operations and the absence of classic testing methods
[0004] The relay protection equipment automatic test system currently used in the power system relies too much on the relay protection tester, and the editing of the test case library is not particularly convenient, and the management of the test cases is also out of the question.

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail according to the accompanying drawings in the description.

[0027] The schematic diagram of each device connection in this method is shown in figure 1 , the communication of each device adopts the network connection, and the tester forms the test case currently needed through the test case editing and management module, and saves it in the database.

[0028] Testers then use the Control Center to read the test case from the database. The control center operates the measured object and the test input device through the communication processing interface, records the information of the measured object and the feedback device during this period, and judges the test result after the test is completed.

[0029] according to figure 2 database planning and structure, and establish a test case database for storing test data. An example is as follows: Test whether the 0.95 times the fixed va...

Abstract

The invention provides a method for automatically testing relay protection equipment. The method comprises the steps of: generating a test input quantity, detecting an output quantity of an object to be tested, and monitoring an intermediate quantity of the object to be tested through a distributed simulation environment, and forming a complete process of a closed-loop test; storing a fixed value, a pressure plate, a message and other information of relay protection equipment to be tested through a manner of a database, and storing the test input quantity and the output quantity of the object to be tested during the testing process; testing input equipment and the object to be tested through network connection; and controlling test input through a manner of command, then receiving the feedback of the object to be tested, finally intelligently comparing with an expected result stored in the database, and storing a feedback result in the database. By adopting the method for automatically testing the relay protection equipment provided by the invention, external properties of the relay protection equipment can be automatically monitored, the reliability of testing of the relay protection equipment and the testing efficiency are improved, and the probability of finding of hidden defects is increased.

Description

technical field [0001] The invention belongs to the field of relay protection in electric power systems, in particular to the automatic testing technology of relay protection equipment. Background technique [0002] There are more and more types of secondary equipment in the power automation system, and the requirements for relay protection equipment are becoming more and more complex: if each region has its own independent version, in this case, it is necessary to conduct detailed tests on all versions , and this will inevitably increase a lot of workload and duplication of labor, the use of automatic testing is a must. [0003] At the same time, it is necessary to test the relay protection equipment and accumulate experience. Without an information aggregation and sharing platform, it will inevitably result in a large number of repetitive operations and the absence of classic testing methods. [0004] The automatic test system for relay protection equipment currently use...
