摘要
为调节风力发电机转速,控制蓄电池充电和负载供电,以PIC16F716型单片机为核心,利用仿真软件Matlab/Simulink,建立了风速、风力矩与功率、发电机功率与转矩、Buck电路模型。结果表明:通过调节Buck电路占空比,对风力发电机输出功率的最大值进行追踪,具有可行性;以定步长寻优控制法,对最大功率点追踪进行算法调节,具有有效性。
In order to adjust the speed of the wind generator,control the accumulator charging and control the load power supply,based on PIC16 F716 chip microcomputer and using the simulation software Matlab/Simulink,the wind speed,the wind moment and power,the generator power and torque and the Buck circuit model were established.The results showed that adjusting the duty cycle of the Buck circuit was feasible for tracking the maximum power of the wind generator and the algorithm adjustment of maximum power point tracking was effective by using the fixed step optimization.
