The invention relates to a relay protection device input and output reliability test method and device, and the method comprises the steps: transmitting a test command to a to-be-tested relay protection device, enabling the relay protection device to carry out the periodic motion according to the test command, obtaining the time scale information of each event in the periodic motion process of the relay protection device in the process, by calculating the time mark information of each event and judging whether the time mark information meets the preset standard or not, the reliability test of the relay protection device outlet is realized, a test method and an automatic scheme are provided for the input and output reliability test of the relay protection device, and the development of multi-round long-term copy test is facilitated. The test method provided by the invention does not need manual intervention, records a test result in the whole process, pops up alarm prompt information after a non-passing condition occurs in the test process, stops the test, protects a fault site, and is convenient for subsequent troubleshooting and positioning.
Description
technical field [0001] The invention relates to the technical field of testing relay protection devices in electric power systems, in particular to a reliability testing method and device for switching in and out of relay protection devices. Background technique [0002] With the continuous improvement of relay protection technology, the boards and cards of relay protection devices are constantly being updated, and the relay protection devices in substations are constantly being updated. The reliability of input and output needs to be verified urgently. The reliability of the input and output of the relay protection device is the basis for the normal operation of the power grid and the guarantee for the reliable removal of grid faults. In engineering practice, serious damage will be caused to power grid equipment due to incorrect acquisition of input, unclosed / disconnected output, and delayed closing / opening of output. In order to ensure that the relay protection device ca...
