摘要
提出了在有光伏并网的线路中三相不平衡及无功补偿的两种方法。第一种方法利用电容电感进行补偿,给出了用电容、电感补偿的参数算法;第二种方法利用光伏并网电路输出补偿电流进行补偿,给出了控制的方案。对两种方法都进行了仿真,同时对比了两种方法的优缺点。
Two methods of three-phase unbanlance and reactive power compensation of the photovoltaic grid-connected line were proposed. The first method was using capacitance and inductance to compensate. The compensation parameter algorithm of the capacitance and inductance was given in this thesis. The second method was using the photovoltaic grid-connected circuit to export the current for compensation. The control proposal was given in this thesis. The two methods were simulated and their advantages and disadvantages were compared.
