摘要
他目前的研究旨在分析远程终端单元的测量结果，并利用状态估计方法检测总线上的不良测量。该研究是在SULSELRABAR(南、东南和西苏拉威西，以下简称SULSELRABAR) PT. PLN的负荷控制单元进行的。分析中使用的数据是通道阻抗数据和RTU测量结果，包括SULSELRABAR电气系统中母线、电压、MVAR注入和负载数据。结果表明，在系统的37辆公交车中，有22辆可以通过RTU进行监控，30辆可以通过加权最小二乘估计方法进行估计。根据状态估计的结果，在27和29总线上出现了不良测量，误差水平分别为0.0575和0.0871。
Power Flow Based Monitoring Of State Estimation Using The Weighted Least Square
his current study aims to analyzing the results of measurements of Remote Terminal Unit and detect bad measurement on the bus by using State Estimation. The research was conducted at Load Control Unit of PT. PLN SULSELRABAR (South, Southeast, and West Sulawesi, hereafter SULSELRABAR). The data used in the analysis were data of channel impedance, and the results of RTU measurements, including data about bus, voltage, MVAR injection, and load data in the electric system of SULSELRABAR. The results reveal that from 37 buses in the system, 22 buses can be monitored via the RTU, and 30 buses can be estimated by using the estimation method with Weighted Least Square (WLS). Based on the results of state estimation, bad measurements occurred on the bus of 27 and of 29, with error levels of 0.0575 and 0.0871 respectively.
