| Abstract:Due to the application of network communication for smart substations, the security measures of secondary equipment become implicit and complicated, which makes it difficult to verify the security measures. This paper proposes a strategy for the verification of security measures for smart substations. Firstly, based on SCD, ICD and SPCD, the model for smart substations is constructed. Secondly, a formalized description mechanism for security measures is presented for computer processing. Finally, the security measures are verified through the simulation on Matlab/Simulink, and the reliability isolation of maintenance equipment and operating equipment is guaranteed. Through the application of a 220 kV smart substation, it proves that the verification scheme is intuitional and effective. This work is supported by Major Project of State Grid Corporation of China “Planning and Operation Control of Large Scale Grid” (No. SGCC-MPLG001-2012) and National Key Research and Development Program of China (No. 2017YFB0903202). |
