Abstract
In order to improve the accuracy of state estimation in power system,this paper proposes a PMU/SC AD A hybrid measurement on the bases of the existing theory.The model divides power system into linear areas and nonlinear areas,and computes voltage vectors of nodes associated with the node with the installation of PMU device in the area of linear areas,and the calculated results is introduced into nonlinear areas as indirect measurement data in the state estimation,thus increase the accuracy of state estimation.Emulation experiment shows this algorithm put forward in this article have a fast computer speed,and can improve systematic redundancy degree in IEEE-14 system.The algorithm has certain practical value.关键词
