| 摘 要： | 通过分析双馈发电机的基本运行原理,推导出了空载数学模型,研究了基于定子磁链定向的空载并网矢量控制策略.结合变论域模糊PI控制理论,利用Simulink仿真平台中的S函数,设计了相应的变论域模糊PI控制器,对双馈发电机空载并网前的定子端电压闭环控制进行仿真.仿真结果说明所采用的变论域模糊PI比模糊PI控制的控制精度高,具有更好的动态响应能力和自适应性.

| Abstract: | With the analysis of the operation behavior and working principle of DFIG,a mathematical model of DIFGs under no-load condition was established and a no-load cutting-in control strategy was developed based on the stator flux orientation theory.In the light of the theory on the variable universe fuzzy-PI control,an adaptive fuzzy-PI controller using the S-function of Simulink was designed to simulate the closed loop controlling for the DFIG stator voltage under no-load condition before connecting to the grid... |
