摘　　要：提出一种基于代理(Agent)、服务器(Server)和客户(Client)的协同合作模式(简称A-S-C模式),实现对电力系统的紧急控制。该控制策略采用抗原能量函数对系统进行稳定性分析,其特点是无需进行多机等值和求解相关不稳定平衡点,具有较快的计算速度。在控制执行端引入快关措施,有利于满足系统故障后稳定运行的需求,同时尽可能减少对机组的冲击。采用IEEE39节点系统对该模式进行了测试,取得了较好的紧急控制效果。A new emergency control strategy for stability of power system, called A-S-C model, is proposed in this paper. The A-S-C model is implemented by the cooperation of three parts, i.e. Agent, Server and Client. In this model, the method based on antigen energy function （AEF） is employed to assess the stability of power system. Since AEF method can calculate system stability margin without the information of multi-machine equivalent and unstable equilibrium points, it performs faster than standard transient energy function-based methods. The turbine fast valving is chosen so as to maintain power system stability under system disturbances, the impact on turbine generator is decreased as well. The presented strategy is verified on the IEEE 39-bus test system.
