摘要

基于双馈感应发电机(DFIG)的风力涡轮机必须在故障和电压下降/膨胀时支持电网。在这方面，低电压穿越(LVRT)和高电压穿越(HVRT)可以用来提高DFIG的性能。本文提出了一种基于模糊控制的控制策略，以提高DFIG LVRT和HVRT的性能。通过MATLAB/SIMULINK仿真，验证了该方法在各种故障条件下电压骤降和电压膨胀的有效性和性能。此外，还将该方法与一些常规方法进行了比较，并对其熟练程度进行了讨论。

An Improved Control Strategy for DVR in order to Achieve both LVRT and HVRT in DFIG Wind Turbine

Doubly fed induction generator (DFIG) based wind turbines must support the grid during faults and voltage sag/swells. In this regard, Low voltage ride through (LVRT) and High voltage ride through (HVRT) could be used to improve DFIG performance. In this paper, a control strategy, based on fuzzy control, has been proposed to improve DFIG LVRT and HVRT capability. The effectiveness and performance of this method has been validated by MATLAB/SIMULINK simulation for both voltage sag and swell under various fault conditions. In addition, this method has been compared with some conventional methods and proficiencies have been discussed.
