Study and realization of Dynamic Security Assessment system Graph-Data integration platform

Dynamic Security Assessment (DSA) is based on analysis of transient stability, voltage stability, small-signal stability, which gives evaluation on multi-contingency and preventive measures or optimization strategies. PSASP Dynamic Security Assessment (PDSA) Graph-Data integration platform is studied in this paper, which supports not only graph configuration, auto-consistent graph and data, drawing of geographical and single-line substation diagrams, but also online system monitor, offline analysis, visualization etc. Three run-states and two frameworks are summarized in the platform. Abundant two-dimensional and efficient three-dimensional visualization is also discussed. The platform of Graph-Data integration in this paper is used in Electric Power Dispatching Centre of State Grid and Guangdong province and so on.
