Description
Summary:In order to avoid the harm on the filter caused by the resonance between the passive part of the filter device and the grid, taking account of the harmonic resonance, resonance detection principle is adopted to optimize the configuration of the filter device. Through analysis of node admittance matrix feature values for the distribution network, the resonant position and resonant frequency are detected according to the impedance spectrum curves. And regarding the voltage total harmonic distortion rate of the power bus as the objective function, the optimal filter installation location and parameters of passive slip are obtained, making filter configuration avoid the resonance occurrence. Results show that the method of the resonance detection principle is used to optimize the configuration of the filter obtaining a good filtering effect, avoiding the resonance occurrence and demonstrate the feasibility of the method by Matlab simulation and instance validation.
