Security and Stability Control System Testing Platform for Guangxi Region Power Grid on RTDS

There is a need to build power grid on RTDS in order to testing performance of security and stability equipment (SASE). The paper divide a large-scale province power grid into four region grid with present RTDS hardware capacity in a view to include all stations installing SASE in a single region grid and disconnect lines as few as possible between adjacent region grids. The paper gives method of manually calculating and modeling node’s power balance, keys of building region grid and matters needing attention transforming parameter format from BPA to RTDS, and then simulating results show that steady state error of some variables are less than one percent, all less than 10 percent and transient characteristics help SASE to start-up to some extent.
