The invention discloses an intelligent substation secondary device testing method and an intelligent substation secondary device testing system. The intelligent substation secondary device testing method is characterized in that testing points are selected to simulate a fault source, and an intelligent substation main control computer clock frequency is acquired; the clock frequencies of the testing points are adjusted to be synchronized with the main control computer clock frequency, and then the testing points are tested to acquire testing data; by analyzing the testing data, the testing of secondary devices is completed. The secondary devices of the intelligent substation are selected to simulate the fault testing source, and the simulated power fault signals are input in the fault testing source, and then the testing data is acquired for the comparison and the analysis, and by analyzing, comparing, and predicting the performances of the tested secondary devices at the same time, the stability of the intelligent substation is accurately evaluated.
Description
technical field [0001] The invention relates to the technical field of power system automation, in particular to a method and system for testing secondary equipment of an intelligent substation. Background technique [0002] Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. At the same time, it is a substation with advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction. In the existing power system, along with the increasing requirements for electricity safety, the requirements for the stability of smart substations are also ...
