Research on Power System Harmonic State Estimation

摘要：

The concepts,functions and implementation methods of power system harmonic state estimation (PSHSE) are discussed in this paper.The harmonic state estimation methods which are being used at present are reviewed.Selecting node voltage phasors as state variables,node voltage pahsors,branch current phasors and injected current phasors as measurements variables,the paper establishes the measurement equations of different configuration and the mathematical model of PSHSE.According to the different measurement schemes,this paper proposes the different method.At the end,the paper analysis the method about extending the observability analysis algorithm of traditional power flow state estimation techniques to harmonic state estimation field.
