摘要
风速超过额定值后,需要有效调节风电机组吸收功率并限制叶轮载荷不超过设计的限定值。在分析风力发电系统原理的基础上,采用自适应模糊神经网络控制器控制桨距角,使机组能保持在额定功率附近发电,仿真结果表明了本文提出方法的有效性。
At high wind speed, in order to effectively regulate the absorption of wind turbine power and limit the load of rotor does not exceed the design value. Pitch angle is adjusted to keep rated output power using fuzzy-neural network control. The Matlab simulation result shows the effectiveness of the proposed methods.
