A fault location method based on hybrid measurement state estimation for a distribution network
微型相量测量单元(micro-phasor measurement unit,μ PMU)为配电自动化的进一步升级提供了良好的量测基础,但现阶段电网中μ PMU数量有限,难以满足传统配电网故障定位的需求.针对该问题,结合电网中μ PMU与智能电表等量测设备,并基于虚拟节点的多重状态估计方法,提出了一种基于混合量测状态估计的故障定位方法.首先,通过等效变换将μ PMU和智能电表的测量信息输入到故障状态估计器当中.然后,利用μ PMU将网络划分为不同…查看全部>>
The micro-phasor measurement unit(μPMU)provides a measurement basis for distribution automation upgrade,but the present stage of the number of μPMU cannot really meet the needs of fault location in a traditional distribution network.To address this,this paper proposes a fault location method based on hybrid measurement state estimation by integrating the μPMU and a smart meter(SM)and considering a multiple state estimation method of virtual buses.First,the m…查看全部>>
