摘　　要：针对大电网灵敏度难以求解的状况,提出了大电网可靠性评估灵敏度分析新方法,通过系统节点可靠性的元件信息以及连通关系,求得灵敏度的相关信息,进而为电力系统规划和运行提供重要的指导意见。通过36节点算例,验证了该方法评估大电网灵敏度的有效性、可行。Since the sensitivity of large power system is hard to solve,this paper proposes a novel sensitivity analysis method for reliability evaluation. It is a method that is able to acquire relevant information of sensitivity through the component information and connected relation of system mode reliability,so as to provide significant reference for electric power system planning and running. The calculation through 36 nodes example proves that the method is effective and feasible in sensitivity evaluation for large power system.
