基于鼠笼异步发电机风力发电控制系统的研究

摘要

The paper describes the control strategy of the cage induction generators for wind turbines and introduce the control strategy of this system. The motor speed is controlled by the motor side converter to fulfill the every operation stage of the wind turbine. At the same time,by controlling the gird side convertor,the DC link voltage can keep stable and the reactive power output of zhe system can be adjusted.The control strategy of this system is proposed,and its practicability is demonstrated by simulation and setting up laboratory plant. Under this control strategy,this system can supply qualified power to the grid.%描述了基于鼠笼电机的风力发电系统,介绍了该系统的控制策略和方法.通过机侧变流器控制电机转速以完成各阶段风力发电的电机控制,通过网侧变流器保持直流母线电压稳定并调节无功输出.研究得出了基于鼠笼电机风力发电系统的控制策略,并通过仿真和实验验证其可行性,结果表明该控制策略可使系统正常运行,保证了基于鼠笼电机的风力发电系统可为电网稳定供电.
