摘要
常规PI调节器参数主要通过传递函数进行整定,并没有考虑系统整体对其影响,基于双馈异步风力发电系统数学模型,依据变流器控制策略对PI调节器进行研究,分析双PWM变流器控制系统的定向方式,提出从整体系统的角度出发,考虑自然频率和阻尼比的约束条件来确定PI参数的协调控制方法,在RTDS中建模仿真,对其控制效果进行仿真验证。
The conventional PI regulator parameters are mainly tuned through the transfer function, but the influence of the whole system is neglected. In this paper, based on the mathematical model of doubly-fed induction generator （DFIG） system, the PI regulator parameters are researched on the basis of converter control strategy. The oriented mode of dual PWM converter control system is analyzed ; the coordination and control method of PI parameters are determine considering the whole system, as well as the constraints of natural frequency and damping ratio. The simulation results in RTDS show the effectiveness of the proposed method.
