Simulation and Visualization System of Power Grid Security Checking

Power grid dispatching plays an important role in the safe and stable operation of power grid. Integrated dispatching system monitor and analysis substation equipment, transmission equipment in a unified mode. Simulation model of power grid dispatching safety checking system is built, to realize the stability analysis and safety monitoring function for checking and validation. According to the grid’s CIM data, a node merging algorithm of network topology is proposed for building power grid topology rapidly. The power grid safety analysis and visualization platform is designed, with a graphical data management. The research results are applied in the State Grid Taizhou Electric Company dispatching integration system, and it works fine.
