针对基于双馈感应发电机（DFIG）的风力发电系统（WECS），研究了两电平空间矢量脉宽调制（SVPWM）和七电平SVPWM直接矢量控制（DVC）策略。仿真结果表明了这两种策略的可行性和有效性。结果表明，与两电平SVPWM相比，采用七电平SVPWM技术的DVC定、转子电流谐波畸变率低，有功、无功功率纹波小。
In this paper, we present a comparative study between two-level space vector pulse width modulation (SVPWM) and seven-level SVPWM strategy in direct vector control (DVC) of a doubly fed induction generator (DFIG) based wind energy conversion systems (WECSs). The feasibility and effectiveness of the two strategies are demonstrated by simulation results. The obtained results showed that, the proposed DVC strategy with Seven-level SVPWM technique have stator and rotor current with low harmonic distortion and low active and reactive powers ripples than two-level SVPWM strategy.
