Anti-misoperation method for testing of microprocessor protection device

Abstract

The invention discloses an anti-misoperation method for testing of a microprocessor protection device. According to the anti-misoperation method for testing of the microprocessor protection device, needed test equipment comprises a test computer, a protection testing system installed in the test computer and a protection tester. The method comprises the following steps that a device function configuration template, a test report template and a protection device test criterion template are established according to the type of the microprocessor protection device to be tested, existing parameters of the actual protection device are input into the device function configuration template, a protection motion logic management unit is generated by test management software according to the actual configuration of the device to be tested and integrated data with requirements of the protection device test criterion template considered, an automatic testing task of the test management software is started after all devices of a system are connected, complete function sequence testing and result judging of the protection device are achieved, and testing data and a judging result are saved into the test report template. The anti-misoperation method for testing of the microprocessor protection device has the advantages that the intelligentization degree is high, the parameters and the configuration the protecting device to be tested are not modified, and therefore reliable anti-misoperation capacity is achieved.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a method for preventing misoperation of a microcomputer protection device test in the field of relay protection test test. Background technique [0002] Electric energy is an indispensable energy in production and family life in modern society. It is provided by the power system. The stable operation of the power system is the key to ensure the safety and reliability of power supply. To ensure the stability of the power system, it is necessary to take necessary measures to isolate the fault in time when the power system fails. This task is realized by various relay protection devices. [0003] The relay protection device is an important part of the power system, and it plays a very important role in ensuring the safe operation of the system. With the development of technology, relay protection devices have experienced several generations of products such as elect...

Problems solved by technology

In this way, due to the many types of on-site microcomputer protection devices, different operation modes, many setting and configuration parameters, and short effective test working time, it often happens that the initial conditions before the test cannot be completely restored due to carelessness of personnel or insufficient understanding of the product after the test. In some cases, there is no problem if the protection device is not tested, and abnormal phenomena occur frequently after the test, which seriously affects the operation safety of the power supply system

[0009] Based on the above practical problems, it is necessary to improve the test method to prevent problems caused by manual operation errors during the test process
