摘要
结合双馈感应发电机(DFIG)的数学模型,分别根据网侧变换器和转子侧变换器的控制目标对其单独进行SVPWM双闭环控制。提出控制系统中二阶PI调节器的参数优化设计方法,从而加快控制系统的响应速度,实现最大风能追踪,使DFIG能够在次同步、同步和超同步状态下进行快速、平稳过渡。最后根据优化设计后的参数对整个系统进行仿真研究,证明了该控制系统的快速性和可靠性。
Based on the mathematical model of the doubly-fed induction generator(DFIG) respectively, this paper adopts the SVPWM double closed loop control strategy according to the grid side converter and machine side converter con- trol target.The second order PI regulator parameter optimization design method is proposed to speed up the response speed of the control system.The novel PI regulator can help to realize the maximum wind power tracking,and make the DFIG transits among the state of the sub-synchronization, synchronization and super-synchronization rapidly and smoothly.Finally the quickness and reliability of the control system are proved by simulation.
