电网电压不对称故障时双馈风电机组多目标优化控制
Multi-objective optimization control of doubly-fed induction generator under asymmetrical grid voltage fault
摘要
Abstract
Firstly,the impact of asymmetric grid fault on double-fed wind turbine is analyzed,and the proportional integral resonant (PIR) controller of rotor side and grid side converter are used to simplify the traditional low voltage ride through control structures; two adjustable parameters are introduced to control the feedforward,which achieves multi-objective optimization control of DFIG during asymmetric grid voltage dip.The model is carefully researched on PSCAD,the results show that the multi-objective optimization control strategies can effectively help DFIG to provide LVRT capability when the grid voltage asymmetric dip occurs.关键词
