Abstract

Harmonic state estimation in power system is allocation of data to amplitude and phase of voltage harmonics (state variables) in the buses of system by using measurements in the system and a special evaluation criteria. Measurements are voltage phasor and current phasor in the busbars and current phasor in the lines of system, and criteria of evaluation is based on weighted least squares method. Harmonic model in the estimation algorithm provide with attention to system topology and measurements achieved in the system. By classification of state variables in a few stages, dimension of model can be reduced to minimum level to increase speed and efficiency of estimation in the system. Results of simulation in the test system show accuracy and efficiency of this type of estimation and its ability to identify the harmonic sources in the system. Some of the characteristics of harmonic state estimation in power system is, it's enforceable with Kalman filter algorithm, it's enforceable by using neural Network, and it's enforceable in unbalanced three phase power systems.
