摘要

为拓宽双馈风力发电机的低电压穿越范围

本文在传统虚拟电阻的基础上引入模糊控制方法来调节虚拟电阻阻值

使其在故障期间可跟随系统的动态变化

能在限制转子电流峰值的同时保证转子电压不超出允许值

且对于较深程度的电压跌落也具有较好的控制效果。在Matlab/Simulink平台搭建仿真模型

仿真结果验证了该控制策略的有效性。

Abstract

For broadening the low voltage ride through range of double-fed wind generator

in this paper

the fuzzy control method is introduced based on the traditional virtual resistance so to follow the dynamic variation of system during the fault period and

at the time of limiting the peak of rotor current

assure the rotor voltage within the permitted value as well as have better control effect for the deep voltage drop.The simulation model is set up by the Matab/Simulink platform and the effectiveness of the control strategy is verified by the simulation result.
