The concept of power system Post-Emergency Rotor Angel Control (PERAC) based on the framework of the third-category control and multi-agents system is proposed in this paper. It has been implemented in the control scheme with On-line Pre-decision System (OPS) to retain the power system's angel stability when the system meets the unexpected cascading contingencies during one fixed updating cycle of on-line emergency control system. The strategy of on-line decision table establishment by using the quantitative power system stability analysis method Extended Equal Area Criteria (EEAC) under this situation is further studied. The simulation results of the real power system of Guangdong district in China are presented in this paper to demonstrate and prove the feasibility and effectiveness of the control scheme.
