为了解决双馈异步风力发电机(doubly-fed induction wind generator,DFIG)不对称电网网侧变换器采用双电流闭环控制策略(double current closed loop control strategy,DCCS)时响应速度慢、动态性能差等问题,提出了根据电流差、电流差变化率在线模糊自适应修正比例积分微分(proportion integration differentiation,PID)控制器参数的Fuzzy PID策略,建立了DFIG网侧变换器数学模型.基于Matlab/Simulink仿真工具,通过模拟电网侧发生不对称电网故障,仿真得到网侧变换器在改进控制策略下的直流侧电压、电流波形.仿真结果表明:与传统DCCS相比,Fuzzy PID策略进一步改善了直流侧电压、电流的稳定性,减少...

To solve the slow response, poor dynamic performance and other problems in the double current closed loop control strategy （DCCS） for grid-side converter in the asymmetric grid of doubly-fed induction wind generator （DFIG）, this paper proposed the Fuzzy PID （proportion integration differentiation ） strategy for online fuzzy adaptive correction PID controller, and established the mathematical model for DFIG grid-side converter. Through the simulation on the asymmetric fault of power grid with using Maflab/Simulink, the DC voltage, current ...
