| Abstract:In order to suppress the overvoltage caused by harmonic resonance in distribution network， it is necessary to obtain accurate information of the resonance， such as resonance frequency， maximum excitation point， maximum observation point and participation factor. To improve the efficiency， a harmonic resonance modal analysis method of distribution network based on adaptive sweep technique is proposed. The proposed method uses adaptive sweep technique to analyze the resonance frequency resonant frequency， and then utilizes modal analysis to obtain the resonance information. Simulation results show that the proposed method can efficiently and accurately recognize harmonic resonance frequency and the maximum excitation node of the distribution network. |
