Current Detection Control of Active Power Filter under Non-Ideal Voltage Source

  • 摘要: 分析了有源电力滤波器(APF)电流(ip-iq)检测法中影响检测精度的因素,包括低通滤波器和锁相环的频率及相位检测误差.为消除电流检测中非理想电压带来的锁相环检测误差,提出改进的电流(ip-iq)检测法.在该方法中,将APF直流侧电压的调整部分单独考虑,调整量加入到经过低通滤波器滤波并经反变换环节得到的基波电流信息中.这样,未经过反变换的直流侧电压调整值不受锁相环误差的影响.仿真验证了改进方案能有效降低非理想电压对电流检测精度的影响,提高APF性能.
