Research on Improved PI-MFR Current Controller in Three Phase Four Leg APF
摘要
Abstract
In three phase four wire power supply system,traditional PI control can not track dc reference volume exactly,and also can’t adequately compensate main characteristic harmonics and low order harmonics. Then, the advantage of PI controller is tracking dc reference without static error in a fast speed,while PR controller can track the ac reference volume errorless and fast. Combining the advantages of them both,this paper adopted a proportional-integral-multiple frequency resonance current controller in stationary coordinates. Finally,building the whole three phase four wire system of APF. By comparison with PI controller, the proportional-integral-multiple frequency resonance current controller has a fast dynamic response and can effectively reduce the rate of total harmonic distortion. The experiment proved the correctness of the theory.关键词
