摘要：

This paper presents a robust algorithm of three-phase state estimation for distribution networks. All kinds of measurements in distribution networks are used in the algorithm, Jacobi matrix becomes constant though phase transform of node voltage and equivalent transform of current measurement. Setting of equivalent weight based on prediction residual avoids the modification by iterations, the above methods reduce the amount of computation. Simulation results have shown the proposed method in this paper is stable and robust.
