In order to solve the problems of low standardization of power grid security and stability control device (SSC) and nonstandard operation management of power grid security and stability control system (SSCS) and lack of standard basis for the application of new technology of SSCS, it is necessary to make a comprehensive analysis of the current SSCS standard system and study the adaptability of the SSCS standard. Fristly, the standard system architecture of SSCS is described, including design and development, network access management, maintenance inspection and operation management. Then, the current situation of SSCS standard system is classified and interpreted, the typical standards for each aspect are introduced, and the development status of standards in each link and the problems in practical application is discussed. Finally, combined with the new requirements of power grid development for SSCS and the new problems in actual operation and management of SSCS, it puts forward suggestions for improving the standard system of SSCS, which has guiding significance for the future revision of relevant standards of SSCS.
