Abstract

The invention relates to a 500kV line relay protection device detection method and system. The method comprises the following steps: receiving a test order of to-be-detected relay protection devices and a test parameter and a standard fixed value of each preset logic protection test case, which are input by a user; acquiring sampling precision of the current to-be-detected relay protection device; generating a test sequence according to the logic protection test case and the test parameter corresponding to the current to-be-detected relay protection device when the sampling precision is greater than a preset precision threshold value; outputting the test sequence to the to-be-detected relay protection device, receiving an action message returned by the to-be-detected relay protection device, and generating detection result information in a preset format of the current to-be-detected relay protection device; generating a detection result of a next relay protection device according to the test order until the detection results of all the to-be-detected relay protection devices are generated. According to the method and the system, the detection accuracy can be effectively improved, the detection steps of testers can be saved, and the time required for detecting 500kV line relay protection devices is shortened.

Description

【Technical field】 [0001] The invention relates to a relay protection device detection technology, in particular to a detection method and system for a 500kV line protection device. 【Background technique】 [0002] Regular inspection of relay protection is the most basic measure to improve the correct action rate of relay protection and ensure the safe operation of the power system. After the relay protection device is put into operation correctly, due to long-term operation, changes in the surrounding environment, failure of device components or changes in characteristics may cause the relay protection device to malfunction. In order to ensure the safe operation of electrical equipment, relay protection must be done Equipment maintenance and testing work. The 500kV line has few power outages and the power outage time is limited. The relay protection of the 500kV line needs regular logic verification and transmission export for the dual main protection and backup protection, ...
