摘要 对三相VSR在电网电压不对称条件下进行建模分析。在网侧功率平衡的基础上,基于正、负旋转坐标系下双电流环控制策略对直流侧电压进行了研究。仿真结果表明,这种控制策略可有效抑制因电网电压不对称所导致的三相VSR直流侧电压二次谐波。 The mathematic model of VSR is established in this paper under the unbalanced source voltage. The system is converted to the dq synchronous rotating frame,and a dual current control scheme is proposed. The simulation results demonstrate the second-order harmonics in the dc-voltage can be reduced.
