The new developed area stability control system in the east part of Heilongjiang power system is introduced in this paper. The control system is composed of 5 old control substations and 2 new control substations, and improves the stability level of the Heilongjiang power system by generator shedding in case of severe faults. The dual microwave channels are used to transmit data and control commands among substations. The configuration of two control units and one administrative unit increases its reliability. Same program runs at every substation to implement different control strategies based on flexible configurations. The strategy tables can be online modified with easy operations. The GPS based accurate time signal is introduced in every substation and the voltage phasors are measured based on it.
