Implementation and Application of Security and Stability Control Strategy Based on Activity Diagram

Abstract

SSC (security and stability control) system is an important facility to ensure the security and stability operation of the power grid and improve the transmission capacity. However, the differentiation of power grid characteristics and the resulting diversity of stability control strategies determine that it is difficult to standardize the stability control system, and the stability control strategy is superimposed. In the process of machine realization, the degree of automation is not high, and personalized programming leads to hidden faults that are difficult to find through conventional means. Therefore, this paper proposes an automatic realization method of SSC code based on activity diagram. First, it sorts out the basic element configuration of SSC strategy and analyzes the relationship between them. Then summarized four procedures of SSC strategy implementation, using a unified description method of the SSC strategy to associate SSC model with the strategy code of SSC device, using standardized model analysis and code Generate tools to automatically generate device codes for SSC strategies. Finally, an engineering example is given, which uses automatic code generation tools to analyze and verify the correctness of the model and the practicability of the code.
