摘　　要：光伏并网逆变器的富余功率容量可以补偿非线性负载的谐波电流。采用能量回馈MPPT算法能够将有功功率逆变器控制与光伏电池输出电压控制结合起来,达到较高的能量效率。利用FBD算法能够实时检测非线性负载电流中的谐波成分,并加以补偿。仿真模型和结果验证该方法的有效性。The capacity of grid-connected PV inverters exceeds the real power of PV cells, which can be used to compensate the harmonic current of nonlinear loads. Higher energy efficiency can be archived by power-feedback control MPPT arithmetic which changes the output voltage of PV cells by changing the inverter power. FBD method is employed to detect the harmonics of load instantaneously. The simulation model and result validate the proposed scheme.
