三相高次谐波与无功补偿的计算机仿真

Simulation of Three-Phase Harmonic Current and Reactive Power Compensation

根据瞬时无功补偿理论,对以三相全控桥整流器为负载的三相有源电力滤波器进行了计算机仿真,仿真结果表明,无论是三相平衡负载还是三相不平衡负载,用有源电力滤波器来补偿无功电流和抑制谐波电流都是很有效的.

Three phase active power filter using three phase full controlled rectifier as load is simulated based on the theory of the instantaneous reactive power. The simulated results show that, with balanced load or unbalanced load, both of the reactive power and harmonics can be suppressed effectively with active power filter.
