豪斯荷德尔正交变换法在状态估计中的应用

APPLICCATION OF HOUSEHOLDER ORTHOGONAL TRANSFORMATION METHOD TO STATE ESTIMATION

本文详细介绍豪斯荷德尔（ＨｏｕｓｅＨｏｌｄｅｒ）正交变换法在状态估计中的应用。该方法与目前状态估计计算中广泛采用的吉文斯（Ｇｉｖｅｎｓ）正交变换法相比具有运行速度快，程序设计简单等优点。经云南大理等地区电业局的现场运行表明，该方法具有数值稳定性高，收敛性好，占有内存小等优点。

This paper describles the application of HouseHodler orthogonal transformation method to state estimation.The method is more rapid at running speed and more simply at designing program then the Givens orthogonal transformation method which is extensively used presently.it has been proved that it run steadily,converge quickly and occupy lesser memory by running at Dali power Bureau.
