摘　　要：暂态稳定性能指标的大小能够反映电力系统事故的严重程度,可以作为事故选择的依据。该文提出一种以选出严重事故为目标,通过快速计算性能指标的综合值进行事故扫描的综合性能指标法。该方法严重事故捕获率高、计算速度快,能够满足动态安全分析系统在线应用的要求。通过NEW ENGLAND 10机系统的仿真算例,验证了该方法的有效性。The transient performance index can reflect the degree of severity of the fault in the electric power system and be the criterion for contingency screening. An integrated performance index method of the contingency screening for filtering severe contingencies by directly calculating the integrated values of the performance indexes are proposed in this paper. The method can capture severe contingency correctly and quickly and can meet the requirement of online dynamic security analysis. The simulation on NEW ENGLAND 10 machines system testifies the validation of the proposed integrated performance index method.
