| 摘 要： | 在分析绕线式异步风力发电机系统转子变流器组成特点的基础上,提出一种新型转子电流混合控制的电路拓扑结构及其控制策略。分析了其中双馈运行和斩波调阻运行两种控制方式之间的切换过程和实现连续过渡的控制规律,并对该风力发电系统进行了动态仿真研究。结果表明,该控制方法兼备双馈控制法和斩波调阻法的一些优点,显著降低了转子变流器的硬件成本,实现了两种控制方式之间的连续过渡,可以满足变速恒频风力发电机系统的要求。

| Abstract: | A circuit topology and its control strategy for rotor current hybrid control in a grid-connected wound rotor asynchronous wind power generator system were presented.The circuit is a multi-functional converter in which the chopper and inverter modes are integrated into one unit.The main purpose of adopting the multi-functional converter is to reduce the cost of the variable speed constant frequency wind power generator system.The generator system is controlled according to its rotation speed.The control strategy of operation mode switching was given.Analysis and simulation results show that the proposed possesses many beneficial characteristics of both doubly-fed control and chopping scheme.It can realize smooth transition between the two modes,and is cheaper than a pure doubly-fed system. |
