基于Crowbar与动态电压恢复器提高风力机低电压穿越
Improve low voltage ride-through capability of wind turbine based on Crowbar and DVR
摘要
Abstract
For doubly-fed induction generator,a new method is proposed to realize wind power LVRT by using combination circuits of Crowbar and dynamic voltage restorer (DVR).When grid faults,by using the complete compensation method control strategy of DVR to compensate for voltage grid failure,maintain a constant maintain a constant.And grid faults in relatively serious,put into Crowbar with DVR simultaneously,Crowbar can limit over current of doubly-fed induction generator in rotor side during the fault.Finally,using the PSCAD/EMTDC environment as the simulation platform.The simulation results indicate that,when grid faults,put into the DVR with Crowbar current,can grid voltage recovery normal voltage,and can effectively limit over current of the rotor side,thereby improve the ability of LVRT of doubly-fed induction generator.关键词
