摘　　要：相位测量单元(PMU)能够实现广域电网运行状态的实时同步测量,已经成为监测和控制电网的关键。但是,由于经济和技术的原因,目前不可能在电力系统的所有节点均安装PMU。因此,通过配置最少的PMU而使电力系统达到完全可观测性得到了广泛关注。为此研究了电网在线路/PMU N-1故障时完全可观测的PMU优化配置问题(OPP问题),并应用差分进化(DE)算法进行求解。提出的方法在IEEE-14、IEEE-30和IEEE-57测试系统上进行了应用分析,验证了该方法的有效性。Phase measurement unit （PMU） is the key device for monitoring the power grid, due to its capability of measurement of operating status and parameters in real time synchronously. But it is infeasible to deploy PMU on each bus due to the cost and some technology. As a result,deployment of PMU with minimum number to satisfy completely observation has been paid much attention. In this paper,we investigated optimal PMU placement satisfying completely observation considering N-1 bus/ PMU outage, and differential evolution （DE） algorithm is employed to solve this problem. Finally, the proposed method is tested on IEEE 14-bus system,IEEE 30-bus system and IEEE 57-bus system,which improved the effectiveness.
