Study on Excitation Converter of Variable Speed Constant Frequency Wind Genetation Systm

将矢量控制移植到风力发电系统的控制,提出了变速恒频风力发电系统交流励磁变频器的控制方案。采用双PWM变换器结构,构建了一套基于TMS320LF2812的风力发电系统,并对系统并网控制、功率解耦控制进行了实验研究。实验结果验证了该方案的可行性。

A wind generation system based on TMS320LF2812 is developed.The field-oriented vector control scheme is transplanted into the control of the system.A control strategy, on the AC excitation converter of variable-speed eonstant-frequeney（VSCF） wind generation system is presented.The control strategy adapts back-to-back PWM converters.Synchronizing control,power decoupled control are studied by the experiment.The experimental results validate the feasibility of the control scheme.
