| Abstract: | In order to solve the problems of malfunction in the power system state estimation,this thesis proposes a more numerically stable method,which is called rank reduction approximation method.The new method is based on the orthogonal transformation and the numerical correlativity theory.The method has a better effect on the solution of the malfnnction problems in the power system state estimation. |
