摘要：

For switched reluctance generator(SRG) with wind power conditions, maximum power point tracking(MPPT)control variables are relatively little, and original switching angle variables are seriously non-linear or even opposite changes in a wide speed range, which make the control difficult and complex. According to the advantages of independent-excitation SRG, a novel power converter for SRG was designed to regulate the excitation voltage independently. The excitation voltage was a new variable of MPPT control for SRG. Meanwhile, a single neuron adaptive control algorithm was proposed to track the maximum power. According to the real-time wind speed, the optimum angular velocity was calculated. And the optimum angular velocity was taken as the input of the single neuron adaptive PID control algorithm. Based on the single neuron adaptive PID control algorithm, MPPT is achieved and the excitation voltage is controlled. Simulation and experiments illustrate that tracking effect of MPPT is excellent at different wind speeds. © 2019, Harbin University of Science and Technology Publication. All right reserved.
