摘　　要：文章提出了一种基于N-1安全性准则的电力系统安全域概念和模型。首先,在工作点向量空间中通过N-1仿真校验确定电力系统运行的安全边界;其次,基于工作点与安全边界的距离计算,进行安全域的安全性评价和控制;然后以算例为支撑,比较安全域方法和N-1进行校验,所得结果一致,表明计及N-1安全准则的安全域模型可达到N-1安全要求,具有实用性。This paper proposes a power system security domain concept and model based on N-1 security criteria.Firstly,the safety boundary of the power system is determined by the N-1 simulation check in the working point vector space.Secondly,based on the distance calculation between the working point and the safety boundary,the safety evaluation and control of the security domain are performed;Support,comparison of the security domain method and N-1 verification,the results are consistent,indicating that the security domain model that takes into account the N-1 security criteria can meet the N-1 security requirements and is practical.
