A Low Voltage Ride-Through Control Strategy of Doubly Fed Induction Generator
摘要
Abstract
Based on an analysis of DFIG stator flux transient period during symmetric and asymmetric grid fault,its influence on DFIG rotor,the LVRT limiting condition using rotor-side converter（RSC） control strategy to achieve low voltage ride-through（LVRT） is found.A DFIG LVRT method combining the improved control strategy with hardware protect is studied when the limiting condition is not met.The method limits the stator＇s and rotor＇s over current,protects the rotor converter and provides power to the grid quickly during serious grid fault.A 3kW DFIG LVRT control experimental system is established.The experimental results prove that the LVRT control method of DFIG is effective.关键词
