Abstract


Active power filter harmonic control as an effective means in recent years, increasing attention has been paid . Important indicators - harmonic distortion for active power filter compensation effect , from the theoretical analysis , computer simulation and experimental start to study the factors affecting the compensation effect , discussed measures to improve the compensation effect . The main contents include : The first chapter introduces harmonic sources and hazards research background and the development status of the active power filter , and gives a basis for argument in this article . The second chapter introduces the main circuit topology of three-phase four-wire capacitor midpoint shunt active power filter works . Derived instruction current equivalent mathematical model of the closed-loop transfer function of the output current and active power filter . Rectifier bridge resistance inductive loads , according to the characteristics of harmonic decomposition of the concept of computing the analytic expression between the harmonic current distortion and circuit parameters . The third chapter analyzes the circuit parameters on the accuracy of compensation . Departure from the two perspectives of the main circuit and control circuit to improve the mathematical model of the shunt active power filter , thus further calculate the circuit parameters of the compensation effect parsed and verified using computer simulation tools . Proposed two measures to improve the compensation effect of the active power filter . The fourth chapter is the experimental part . On the basis of the analysis in the previous chapters , a 15 kVA active power filter prototype experimental verification on the accuracy of compensation . The fifth chapter is a summary of this research and the outlook for future work .
