Automatic testing method and system for stability control device

Abstract

The invention discloses an automatic testing method and system for a stability control device. The testing method comprises the steps that S1, the tested sub-machine is connected with the upper computer system, and the sub-machine is connected with the standard source module and the input module; S2, a system is started, and an upper computer is connected with a database to inquire and read test data; a test task is connected; S3, the stability control protection device is connected with the standard source module and the input module, and the selected test case is executed, the test case is executed according to the test requirement, and the stability control sub-machine acts or does not act according to the test case requirement and is compared with a verification item in the test case,if the requirement is met, the test item passes, otherwise, the test item fails; a test result is stored in a database; and S4, after all tests are completed, a test report is output. The test systemcomprises an upper computer, a sub-computer, a communication function module, a standard source module, an input module, an interface function module, a test case database and an automatic test control module. According to the invention, the functions of quickly building a test environment, remotely testing in a one-key manner, outputting a test report and the like can be realized.

Description

technical field [0001] The invention relates to the field of power system stability control and protection, and is used for automatic testing of stability control devices. Background technique [0002] The stability control device is a safety and stability control device, also called a safety control device. Its main function is to ensure the stable operation of the power grid. Its principle is generally based on changes in the voltage, frequency, and load of the power system; Part of the load can be cut off through the stability control device to ensure that the large power grid returns to the normal state quickly; if the output of the power plant causes the transmission capacity to be lower than the actual power of the power plant, the generator set is cut off, and the stability device is the second line of defense to ensure the safety of the power grid. device supplement. [0003] In order to ensure the reliable operation of the stability control device, regular testing ...

AI Technical Summary

Problems solved by technology

The traditional test method requires manual operation of many instruments and equipment, and because the distance between the two stability control sub-machines is usually large, the required test environment is also very complicated.

In addition to low efficiency, inaccurate testing, and difficulty in judging test results, such traditional methods are also difficult to build in their own testing environment.
