独立运行风力发电系统功率控制器的研究与设计

通过对独立运行风力发电系统的特性和永磁同步电机数学模型的分析与研究,提出了通过调节电磁转矩-转速特性调节功率的一种控制策略,使风力发电机输出在额定风速以下自动跟踪负载用电量。运用此控制策略采用单片机作为控制芯片,设计了用于控制发电机输出功率的电子调节装置,有效地解决了独立运行小型风力发电系统功率平衡问题。

Research and design of a power-balance controller in stand-alone wind energy generation system

Through the characteristic analysis of wind energy carried out,research and analysis on characteristic of Stand-alone Wind Energy Generation System and math's model of the PMSG.Advanced a control strategy with regulate power via adjusting the machine electromagnetic torque-rotate speed use in Stand-alone Wind Energy Generation System,and the wind energy generator automatically track power of load under the rate wind speed.A electronic power conditioner of generator output was designed based on a microchip using this control strategy.It effectively solves the problem of the unbalanced power in the system.
