Power system harmonic state estimation based on generalized measurement and robust least squares
The text introduces the harmonic state estimation and its mathematical model. The relevance and differences between least squares and representative by Huber way of robust least squares are expounded. It describes the advantages of robust least squares. Robust least squares that combines of robust estimation principle and least squares by equivalent weight effectively solves the issue that least squares does not resist Gross error. The text sets up a mathematical model of distribution network by using Matlab, so that receives the synchronous measurement data of harmonic for researching. When measurement error with normal distribution error of Gross error，it is to the harmonic state estimation with least squares and robust least squares. The result proves the effectiveness of robust least squares.
