摘要
在讨论无刷双馈发电机数学模型和功率控制的基础上,分析了无刷双馈风力发电系统的原理与结构,重点讨论了无刷双馈发电系统在额定风速一下的运行与控制方法。运用粗调、细调相结合的方法简单而有效地实现了系统的最大风能捕获。风力发电机在并网和脱网时都需要控制使其对电网不要造成太大的冲击,据此该文讨论了柔性并网和解列过程及其相应的控制方法。
Based on the discussion of the mathematical model and power control of brushless doubly-fed generator,this paper analyses the principle and structure of brushless doubly-fed wind power generation system,focusing on the brushless doubly-fed wind power generation system in operation and control below the rated wind speed. The use of coarse-tuning and fine-tuning combination can achieve the greatest wind energy capture simple and effectively. When wind power generators cutting-in grid or cutting-off grid,the system need to be controlled and the wind power generators should not cause too much impact on power grids. This article mainly discusses the process of the brushless doubly-fed wind power generation system flexible cutting-in and cutting-off grid,and its corresponding control method.
