| Abstract:Due to the application of network communication for signal association in smart substation secondary system, the security measures of secondary equipment for smart substations become implicit and complicated. For the sake of reducing the risk of maintenance associated with protections of the smart substation, this paper proposes a novel method for security measures generation based on formalized description mechanism. This method starts from checking SCD, then generates the model of security measures. Under the circumstances of combining models and deduction rules, the maintenance security measures are automatically generated for a maintenance task based on a formalized description mechanism. In order to improve the reliability of the final maintenance security measures, this paper proposes a visualized verifying method for maintenance security measures. The implementation of 220 kV substation has proved the feasibility of the proposed technical solution. This work is supported by Major Projects of State Grid Corporation of China (No. SGCC-MPLG001-2012). |
