不对称电压跌落下双馈风电机组无功极限分析
Reactive power capability analysis of Doubly-Fed induction generators under unbalanced grid voltage drop conditions
摘要
Abstract
It is analyzed that the stator side maximum current restricts reactive power limit of DFIG under the unbalance voltage drop.A reactive power limit curve is gotten from the relationship among positive and negative sequence current of rotor dq-axis,stator active power and reactive power that are given,according to three kinds of limitations,as well as four different control objectives.A limiter is designed based on the reactive power limit curve,and a DFIG simulation is carried out.The results show that the limiter can effectively reduce the times of input crowbar action,improve system performance of low voltage ride through.关键词
