摘　　要：为提升兆瓦级永磁风电系统并网效率,研究电网电压定向矢量控制最大功率柔性并网策略,实现了电压-电流双闭环SVPWM控制;采用单同步坐标系软件锁相环技术,实现网侧输出电压与电网电压同步,以获得电压稳定和最大功率输出。4种不同风速下并网性能的仿真结果表明了电网电压定向矢量控制最大功率柔性并网策略的有效性。To improve grid connection utilization of MW-level permanent magnet wind power systems,the maximum power flexible grid connection strategy with the grid voltage oriented vector control was used to realize voltage-current double closed-loop SVPWM,and single synchronous reference frame software phase locked loop was used to realize grid output voltage follow as grid voltage,then voltage stability and the maximum power output control were realized.Effectiveness of maximum power grid connection under the grid voltage oriented vector control was verified by simulation under multiply wind speed.
