Modeling and Control Technology of Doubly-fed Induction Generator Based Wind Turbine in Power Grid with Transient Harmonic
摘要
Abstract
Transient harmonics caused by commutation failure,excitation inrush current and impulsive loads entering the power grid can easily lead to serious consequences such as converter overcurrent and disconnection as well as unit stability damage in the doubly-fed induction generator(DFIG).To improve the operating performance of DFIG in the power grid with transient harmonic and improve its power quality fed into the power grid,the mathematical model of DFIG in the power grid with transient harmonic is firstly established.Secondly,a control strategy based on repetitive control regulator is proposed,which achieves the control objectives of rotor current balance and sine as well as stator current balance and sine under transient harmonic impact,respectively.Afterwards,the control performance of the proposed control strategy is analyzed,including harmonic voltage anti-interference performance and stability performance after switching the control target.Finally,based on the hardware-in-loop simulation platform,the effectiveness of the proposed control strategy is experimentally verified.关键词
