摘要
大型兆瓦级风力发电机是近年来风电机组的发展趋势,其控制系统变得越来越重要,对其的设计要求也变得越来越苛刻。此外,对风电机组的性能和结构性载荷都取决于对控制器的认识为风电机组的研究带来的新动力。将控制器的任务扩展到减轻结构性载荷激励了对寻求新的利用叶片节距系统来使结构性载荷的减轻最大化的控制策略的探究。为了加强对用于兆瓦级风电机组的控制的可能性和潜力的认识,文章对其进行了概要介绍,并讨论了控制系统在风能技术中的地位及其作为一种综合了开发者的洞察力的技术的作用。
With the recent trend towards large multi-MW wind turbines, the role of the control system has become increasingly important and its design increasingly demanding. Furthermore, the realisation that not only the performance of the machine but also the structural loads depend on the controller, has given research into the control of wind turbines a new impetus. The extension of the role of the controller to alleviate structural loads has motivated the exploration of novel control strategies, which seek to maximise load alleviation by exploiting the blade pitch system. An overview to raise awareness of the possibilities and potential of control for multi- MW wind turbines is presented. The place within the wind energy technology of the control system and its role as an integrating technology together with the perspective of the developers are discussed
