Based on the principles and advises, proposed in this paper, of coordination and optimization for GPG (Guangdong Power Grid) and CSG, a scheme of security-stability control for GPG 500 kV system is set down: The security-stability control system of GPG takes order of load shedding only from the Luodong main substation, setting off the other communication channells with CSG to stand by, and at the same time, employing certain measures such as unit tripping, operation mode adjusting and so on to realize the coordination and optimization of three defense lines. The scheme is compact, effective and accessible.
