Simulation study for harmonic compensation system with synchronous machine based on Park transformation

Abstract

Based on the Park transformation method, the harmonic compensation theory of synchronous machine is analyzed, the d-q-0 mathematical model and the equivalent circuits are proposed to represent the harmonic compensation system with synchronous machine, on which the working status of the reactive harmonic compensation system with synchronous machine is researched. To study the effect caused by resonance capacitor in field circuits on 5th and 7th harmonic compensation, a 4-pole synchronous machine is selected as a part of harmonic compensation system, which is convenient to calculate the optimal values of resonance capacitors when harmonic compensation reaches electric standard. By means of MATLAB, the simulation model, based on the reactive harmonic compensation system with synchronous machine, is built to obtain simulation results. The simulation results illustrate that the proposed model is valid on the basis of harmonic compensation theory of synchronous machine, and harmonic compensation is to come true by modulating the value of resonance capacitor.
