电网电压突升引起双馈感应发电机(DFIG)定子绕组上的瞬态直流磁链分量比电网电压突降更大,从而导致更严重的定、转子电流和转矩振荡。分析了双馈风力发电机在电网电压突升时的动态行为。基于分析结果,虚拟电阻控制策略管理最好的抑制转子电流和转矩振荡,但延长了瞬态持续时间,导致较高的转子电压。因此,本文提出了一种虚拟阻抗控制策略,以提高双馈风力发电机的高压穿越能力。为了提高系统的动态性能,提出了虚拟阻抗优化算法。仿真和实验结果验证了该控制策略的有效性。
Grid voltage swell causes a transient dc flux component on doubly fed induction generator (DFIG) stator winding even stronger than grid voltage dip, resulting in a much more serious stator, rotor current, and torque oscillation. This paper analyzes the dynamic behavior of DFIG during grid voltage swell. Based on the analysis results, the virtual resistance control strategy manages best to suppress the rotor current and torque oscillation but prolongs the transient duration, resulting in a higher rotor voltage. Thus, this paper proposed a virtual impedance control strategy to enhance the high-voltage ride-through capability of DFIG. In order to improve the dynamic performance, the optimization algorithm of virtual impedance is proposed in the paper. The effectiveness of the proposed control strategy was verified by simulation and experimental results.
