摘要
在大型风力发电机中,为了追求高的风能利用系数和不断优化的输出功率曲线,变桨距型风力机已经显现出越来越大的优势。本文以国电电力太仆寺旗蜗牛山风电厂3MW风电系统为研究背景,对电动变桨技术进行研究,分析了电动变桨系统的构成、运行状态,并提出了一种控制策略。通过仿真,建立了电动变桨系统的模型,并验证了控制策略的可靠性。
In order to get high wind energy utilization factor and output power curves which continuously optimized , the variable pitch wind turbine shows more and more its advantages .An electric pitch technology is researched on the background 3MW wind power, which consists of structure and running status , and a control strategy is proposed .Finally, the electric pitch system model is built and the reliability of control strategy is verified by simulation .
