摘　　要：双馈电机变速恒频风力发电系统是通过调节转子绕组励磁电流的频率、幅值、相位和相序来实现变速恒频控制的。分析了双馈电机工作原理和数学模型,并设计了基于TMS320F2812DSP的变速恒频双馈风力发电机的励磁控制试验系统。对电机的并网控制以及电机的自并励启动进行了试验研究,为变速恒频双馈风力发电机励磁控制策略的设计奠定了基础。The variable - speed constant - frequency control is implemented by adjusting the frequency, amplitude, phase angle and sequence of excitation current of rotor winding in a variable - speed constant - frequency wind power generation system with double feedback function. The working principle and mathematical model of generator with double feedback function was analyzed and the excitation control experimental system based- on TMS320F2812DSP for variable -speed constant -frequency wind power generator with double feedback function was also designed. The control connecting generator to electric power grid and self - shunt - excitation start - up of generator of a variable -speed constant - were tested, which has laid better designing foundation for excitation control frequency wind power generator with double feedback.
