| 摘 要： | 充分利用风能是风力发电控制的主要目的之一,为达此目的,基于原有的直驱式风力发电系统电路拓扑结构,在整流器和逆变器之间加入了Buck-Boost电路,通过控制该电路中开关器件的开断,保证该风力发电系统输出有效电压,从而保证有功功率流向电网或负载,实现风力发电系统的最佳功率系数.基于风力发电机输出功率特性曲线,详细阐述了采用该风力发电系统实现最大风能利用的搜索算法.该算法具有不再需要测风速和电机转速的优点.通过实验验证比较,新系统能实现风能的最大利用.

| Abstract: | Making full usage of wind enegy is one of the main control objects in the control of wind power generation.Based on original wind power generating system,the Buck-Boost converter was arranged between the AC/DC converter and inverter.By increasing or decreasing the duty cycle of the Buck-Boost converter,the Root-Mean-Square(RMS) of output voltage was outputed,so that the active power was guaranteed senting to a utility grid.Based on the power curve,the Maximum Power Point Tracking(MPPT) searching algorithm was elaborated without speed sensors.The tests prove that the proposed system can extract maximum wind energy. |
