摘要
在对定速风力发电机建模的基础上,针对大型风力发电机功率控制中相互矛盾的要求,结合PI控制器,采用了线性二次最优控制,对仿真与传统的PI控制进行了对比,仿真结果表明:运用此控制器,控制效果要好于单独的PI控制器。同时,对桨矩角采用不同的权重时,输出功率、发电机转速、输出转矩都将发生变化。
Based upon model for fixed velocity wind turbine, while considering the contradictory demands in wind turbine, this paper put forward linear quadratic optimum controller combined with PI controller. Traditional PI controller was compared with it by simulation. The result of simulation showed that the effect of linear quadratic optimum controller was better than sole Pl controller. When applied different weight for pitch angle, the wind turbine would vary in output power, generator velocity and output torque.
