摘要
介绍了交流励磁变速恒频风力发电系统运行的基本原理及发电机的定子磁链定向向量控制技术。构建了基于DSP+IPM的系统实验平台,进行了发电机空载运行及并网过渡过程、亚同步、同步、超同步3种状态下的变速恒频发电等工况的仿真和实验,通过对实验结果的分析验证了理论分析的正确性,为该系统的进一步深入研究建立了一定的实验基础。
The basic theory of the AC excited VSCF wind power generation system and the vector control technique oriented by the stator flux of the generator was introduced. The experiment system has been established based on DSP ＋ IPM and done some research study on several rtmning condition including standing alone and variable speed constant frequency generating at sub-synchronous, synchronous, super-synchronous speed has been done. The credible experiment result verified the validity of the theoretical analysis and laid the experiment fotmdations for further study on the system indepth.
