Description

TECHNICAL FIELD

[0001] The present application relates to the field of power systems, in particular to a strategy table-based automatic detection system and method for a stability control device. BACKGROUND

[0002] The stability control device is the "last line of defense" of the power grid. When a serious fault occurs in the power grid, leading to system angle instability, voltage collapse or frequency collapse risk, the stability control device can quickly and accurately execute the predetermined control strategy to pull the system back to a stable state and prevent large-scale power outage accidents. The correctness, rapidity and reliability of its action are directly related to the safety of the power grid and the reliability of power supply to users.

[0003] Currently, the on-site testing of the stability control device still remains in the stage of traditional testing methods, including: analog quantity / switching quantity injection testing: using a relay protection instrument or a small signal debugging tool made by the manufacturer to simulate the electrical quantity and switching quantity when a fault occurs, and injecting them into the input circuit of the stability control device to observe whether the action logic, outlet behavior and message record of the device meet the expectations. In the aspect of transmission testing, after confirming that the device logic is correct, actual outlet transmission testing is performed to verify whether the trip command issued by the device can correctly act on the target circuit breaker. The traditional testing method has great limitations in the simulation of complex faults such as developing faults and multiple faults under the background of increasingly complex stability control strategies, especially in the aspect of manual testing, which is tedious, inefficient and time-consuming, and the test cases are difficult to cover all the strategy tables, and even if the simulation signal is not handled properly or safety measures are not in place, it may cause misoperation risk and refusal to operate.

[0004] Therefore, it is urgent to study a strategy table-based automatic detection system and method for a stability control device to realize the automatic detection of the stability control device on site, improve the test case coverage and detection efficiency, and reduce the safety risk of on-site testing.
