| 摘 要： | 电压源并网逆变器交流侧采用LCL滤波器进行滤波,在获得较好滤波效果的同时,也增加了系统复杂性,降低了系统稳定性.逆变器并网电能质量及其功率因数,尤其在非理想电网条件下,通常需要直接并网电流控制加以确保.而桥臂侧电流的控制能较好地将桥臂电流限制在电力电子功率模块的允许范围内,并且较好的桥臂电流有利于电力电子功率模块的有效...

| Abstract: | Although harmonics in AC side of a grid-connected voltage source inverter(VSI) can be filtered out with LCL filter better than with L filter,the three-order characteristic of LCL filter makes the system complicated and unstable.It is found that the power factor and power quality of the grid-connected VSI can be guaranteed only by direct grid-side current control,especially under the non-ideal grid condition.And at the same time,the arm current can be better limited to allowable value of power electronic blo... |
