基于混合量测的二次线性状态估计方法及其工程应用
Hybrid measurement based secondary linear state estimation methodand its engineering application
摘要
Abstract
In the state estimationbased on hybrid measurement of the phasor measuringunit (PMU) and supervisory control and data acquisition (SCADA), once calculations are based on the traditional nonlinear model,itwill face some problemssuch as difficult to determine PMU measurement calculated weight, inaccurately processing of PMU measurement bad data, the change ofphase angle reference point andmaturecommercial program, etc.In order to solve the above problems, this paper proposes a new secondary linear state estimation method with hybrid measurement. This method uses the voltageamplitude of each node and phase angle estimation of the result based on the convergence of traditional nonlinear state estimation and thePMU measurement to re-calculate the secondary linear state estimation. The effectiveness of the method proposed is illustrated using actualexample.关键词
