摘　　要：通过电磁暂态仿真软件PSCAD/EMTDC验证了并联有源电力滤波器的谐波检测算法及滞环控制算法,论证了并联有源电力滤波器主电路中最重要的参数直流侧电容电压设计原则,并在TMS320LF2407中设计了有源滤波器的软件结构.实验表明,基于瞬时无功功率理论的检测算法能满足并联有源电力滤波器的谐波提取要求,直流侧电容电压需要达到一定值才能控制输出指令电流.The shunt active power filter harmonic detection algorithm and hysteresis control algorithm are verified through the electromagnetic transient simulation software PSCAD / EMTDC; design principles of the shunt active power filter in the primary circuit of the most important parameters--DC bus voltage are demonstrated; and the TMS320LF2407 in active filter software architecture is designed. Experiments show that detection algorithms based on instantaneous reactive power theory could meet the harmonic extracting requirements of shunt active power filter, and the inverter could control the output comman.ding current when DC bus voltage reaches a certain value.
