直驱永磁风力发电系统机侧谐波的抑制
Machine side harmonic suppression of direct drive permanent magnet wind turbine system
摘要
Abstract
A wind power generation system employing back-to-back three-level converters instead of the traditional two-level machine side converter was presented. The diode neutral point clamped three-level converter in the rotor synchronous rotating coordinate of stator current control was adopted, which could suppress the wind power generator current harmonic. A harmonic suppression strategy considering the neutral point voltage balance was proposed. The three-level and two-level converter direct drive permanent magnet wind power generation system was compared. The results show that the three-level topology can effectively restrain the harmonic current of generator in different speeds and loads, and can improve the efficiency of the system.关键词
