摘　　要：探讨双馈发电机并网过程的运行原理,研究了基于定子磁链定向矢量控制技术的发电机并网控制策略,对比和分析了空载并网和负载并网的控制原理。负载并网方式并网前接有独立负载,发电机可以参与风力机的能量控制,降低了对风力机调速能力的要求,减小了风对风力机的应力;建立了负载并网控制的仿真模型,仿真结果表明:并网后冲击电流较小,负载并网方式是一种较理想的变速恒频(VSCF)风力发电并网方式。Running principle of the grid-connection process of doubly-fed generator was discussed.Grid-connection control strategy of generator was investigated based on stator-oriented vector control technique.Contrasting and simulating the principle of the grid-connection with load and with no load,the generator of the load cutting-in control can control wind energy in cooperate with wind turbine,which can relieves the stress of windturbine from wind and improve the speed adjustment ability of system.The simulation ...
