Research on Optimization Method of Passive Resonance Damping of Hybrid Active Power Filter

The hybrid active power filter (HAPF) is an effective measure to suppress the harmonic resonance of power system with high-voltage and large-capacity harmonic compensation. Compared with the single use of active power filter (APF), the passive resonance of HAPF further reduces the capacity of APF and improves the large-capacity application. Thus, it is an important scientific issue to study the passive resonance damping relationship of HAPF. This paper analyzes the passive damping resonance method of HAPF in Tokamak power supply. Based on the harmony search model, a parameter optimization method is proposed, and the improved harmony algorithm is introduced to solve the passive damping optimization parameters. The passive damping optimization method is validated by MATLAB/Simulink simulation and experiments.
