基于瞬时无功功率理论的并联型两电平有源电力滤波器仿真计算与实现：谐波抑制、无功补偿与电网电压条件下的高效稳定运行,基于瞬时无功功率理论的并联型两电平有源电力滤波器仿真计算与实现：谐波抑制、无功补偿及电网电流优化（同学定制），运行条件为电网电压22kV。,两电平有源电力滤波器仿真+计算+不低于2小时（同学定制）01) 并联型+APF有源电力滤波器02)谐波检测采用基于瞬时无功功率理论的dp变检测方法；03)采用电压外环+电流内环双闭环控制；04) 电压外环：APF直流侧电压采用PI控制，稳定性好（若稳定性较差，会影响补偿效果）；05) 电流内环：APF电流调节采用滞环控制；06) 可实现谐波抑制和无功补偿功能；07) APF补偿后，电网电流THD小于5%；08) 仿真模型主要涉及三相交流电压模块、非线性负载、信号采集模块、示波器模块、LC滤波器模块、谐波检测模块、控制模块、通用桥模块、低通滤波器模块、坐标转模块、锁相环模块等。9) 各个模块分类明确，理解容易。运行条件：电网电压 220V，频率50hz。运行效果：APF投入前，电网电流THD为12.96%；APF投入 <link
