摘要
本文提出用豪斯霍尔德正交变换算法,求解电力系统的状态估计问题。它是通过豪氏变换阵,直接对量测方程的加权雅可比矩阵和加权残差向量进行正交变换,降低了采用法方程算法的条件数,提高了解的数值稳定性,适合于求解运行在病态条件下的电力系统的状态估计问题。
In this paper, the Householder orthogonal transform algorithm is used to solve the problems of power system state estimation. The orthogonal transform is directly conducted for the weighted Jacobi matrix and the weighted residual vector of the measurement equations by using the Householder transform matrix. This algorithm reduces the condition number of using normal equation algorithm, raises the numerical stabillty of the solution, and is fit to solve the state estimation problem of a power systems which operates under a morbid condition.
