摘　　要：随着风电机组单机容量的不断增大,发电机并网时的电流冲击已不能忽视,必须对并网控制技术进行深入研究。在总结现有风力发电机并网技术的基础上,研究了交流励磁变速恒频风力发电机与电网间的“柔性连接”特性,即可通过励磁控制调节发电机输出以满足并网条件。将磁场定向矢量控制技术移植到并网控制中,建立了交流励磁变速恒频风力发电机并网控制策略,最后进行了实验研究。With the increasing capacity of wind power generators, the current impact on grid connection could not be ignored, thus the grid connection techniques should be investigated in depth. In terms of existing grid-connection techniques of wind power generator, the characteristics of ＂flexible connection＂ between AC-cxeited VSCF （variable-speed constant frequency） wind power generator and grid are analyzed to make generator output voltage meet grid connection condition by excitation control. By transplanting flux oriented vector control technique into grid connection control, the strategy of AC-excited VSCF wind power generator is developed. In addition, the experimental research is also conducted. This work is supported by National High Technology Research and Development Program （863 Program） of China （No. 2001AA512023）.
