| 摘 要： | 广域测量系统的根本在于对母线的幅值和相角进行精确的测量。在整个广域测量系统的测量满足一定的冗余度的情况下，采用加权最小二乘法对测量值进行状态估计，并且对不良数据进行检测。本文最后应用经典的WSCC9节点系统进行算例仿真，验证该算法的可行性和有效性。

| Abstract: | Wide-area measurement system is the essence of the magnitude and phase angle of bus accurate measurement. In the whole wide area measurement system of measurement to meet a certain redundancy in the case, the measured value using the weighted least square method for state estimation and bad data in this for Detection and Identification. This last application of the classic examples WSCC9 node system simulation to verify the feasibility and effectiveness of the algorithm |
