摘　　要：为了更好地实现风力发电机并网控制,从而有效地减小风力发电机并网冲击电流和保护整个并网控制系统,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;最后在利用PSIM仿真软件进行仿真研究的同时也借助了南车株洲电力机车研究所有限公司背靠背试验平台(Back-Back Test Bench)对整个并网过程进行了试验研究。仿真和试验结果验证了该并网控制方法的正确性与有效性。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 protecting 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, Back-Back Test Bench in our company also is employed to carry out the entire connected-grid process. Simulation and test results verified the correctness and effectiveness of the control strategy.
