Study of Improving Low Voltage Ride - Through Capability of Doubly - Fed Induction Generator by Using DVR

Abstract:

with the increasing proportion of wind power in whole power system ,the influence between wind power system and grid become more and more seriously ,so it is great important to research how to keep the connection between the wind power system and grid when grid voltage drops .The paper presents a new method to realize the low voltage ride - through (LVRT) of DFIG by using dynamic voltage restorer (DVR). Once the grid voltage drops,DVR will be put into use and produce compensation voltage to keep the stator side voltage steady .And it also can stop operation after the fault resolution.The paper builds a simulation model of DFIG and gives simulation results on PSCAD/EMTDC platform .
