摘　　要：为有效减小发电机并网冲击电流,从而实现风力发电机安全并网,在此详细分析了空载并网方法的原理,并根据该原理设计一套完整的并网系统,最后利用PSIM进行仿真研究的同时借助背靠背试验平台对整个并网过程进行了实验研究。实验结果验证了该并网控制方法原理的正确性和有效性。In order to achieve the connected-grid control of doubly-fed wind power generator,thus effectively reducing the impact of the connected-grid current and protect the whole connected-grid control system.The principles of no-load connected-grid control method are analyzed,according to the principle,a complete connected-grid control system is designed.While the simulation software PSIM is used to simulate the control strategy,the back-back test bench is also employed to carry out the entire connected-grid process,finally the test results verify the correctness and effectiveness of the control strategy.
