双馈风力发电机并网控制研究

Research of Grid-connected Control of Doubly-fed Wind Generator

为降低随机性、波动性和间歇性对风力发电并网安全性、稳定性造成的不利影响,提出了双馈风力发电并网控制的主要策略,对PI和模糊PI控制以及PI控制电流内环仿真进行了分析,逐步将各种不利因素带来的影响降到最低,使双馈风力发电机并网后的运行更加安全可靠。

In order to reduce the adverse influence of randomness,volatility and intermittent on grid-connected safety and steady of wind power generation,the paper proposes main countermeasures of grid-connected control of doubly-fed wind generator,analyzes PI,dim PI control and PI control current inner ring simulation,and reduce the influence of adverse factor step by step,to make the operation of grid connection of doubly-fed wind generator safer and more reliable.
