The stable operation of the safety and stability control system is the guarantee of power grid security, and improving the detection technology of the stability control device is the key means to reduce potential risks. This paper proposes a knowledge graph framework for stability control strategy, which condenses a large amount of information in the strategy text into a structured knowledge network. Based on the requirements of stability control strategy retrieval, the construction of knowledge graph is divided into strategy entity graph, system conceptual graph, test case graph, state sequence graph, strategy verification graph. The construction can solve the problems of inspectors retrieving strategies and automatically generating test cases. The detection platform framework of a stability control system driven by a knowledge graph is designed to realize the three main points of detection technology: full coverage of detection functions, test automation, and device portability.
