摘要：
Three-phase state estimation for distribution network proposed based on PMU, using the weight least square (WLS) to establish this algorithm. Currently, the measurement of distribution system state estimation is mainly from the SCADA system with little PMU application in distribution network. In order to improve the redundancy in state estimation, it needs to add the pseudo measurement and virtual measurement. According to the different measurement devices, get the different precision of the measurement, which requires considerations of weighted measurement operations. In the end, the algorithm is effective and feasibility, which is proved by an example that 37nodes system.
