一种开关磁阻风力发电机功率变换器拓扑设计
|
摘要
针对开关磁阻风力发电机在低速时输出功率较低的问题,根据开关磁阻发电机的运行原理,对传统的功率变换器加以改进,提出一种新型功率变换器拓扑。新型拓扑有2种工作模式:全绕组励磁和部分绕组励磁,针对不同的转速选择不同的工作模式,从而达到提高输出功率的目的。为验证其可行性,分别用传统功率变换器和新型功率变换器对单相外转子U率变换器提高了低速运行时发电机的输出功率和效率。
Considering the small output power of switched reluctance generator(SRG)at low speed,this paper proposes a new power converter topology based on the operation principle of switched reluctance generator,aiming to improve the performance of traditional power converter. The new power converter includes two working modes:full winding excitation power generation and partial winding excitation power generation,which are applied to different speed to increase the output power. To verify the feasibility of proposed converter,simulation and experiments on the SRG with single phase,external rotor,U-shaped stators are conducted,compared with the traditional power converter. The simulation results and experiment results show that the new power converter increases the output power and improve the efficiency of SRG at low speed.
