1、双馈风力发电连续运行实验研究摘要:目前,人类面临着能源和环境两大迫在眉睫的问题,因此利用可再生、绿色环保的能源,如风能、水能和太阳能等作为重要的清洁替代能源,对于缓解近年来的问题具有重大意义,日益受到人们的重视。而风能独特的优点倍受各国学者关注,风力发电技术已成为竞相研究的热点。风力发电系统的控制问题研究成了热门课题。本文首先分析了当今世界各国风力发电的发展状况,介绍了我国风力发电事业状况,分析了风力发电的发展前景,在此基础上提出了本课题研究的重要意义。简要介绍了变速恒频双馈风力发电机的运行研究状况,由此引出我们的主题:双馈风力发电连续运行的实验研究。其次,简述了双馈风力发电
2、机空载并网运行,并且深入进行并网后连续运行的研究,其运行区域:低于额定风速时,实行最大风能追踪控制或转速控制,以获得最大的能量或控制机组转速;高于额定风速时,实行功率控制,保持输出稳定。并得出连续运行控制策略。最后,对双馈风力发电机并网后进行实验研究,只对其功率控制进行研究,通过数据的分析,得出相应的结果。本文研究的风力发电连续运行具有很基础,实用现实意义。关键词:风力发电;变速恒频;双馈风力发电机;空载并网;功率控制IIExperimentalstudyofcontinuousoperationofdoublyfedwindpowergenerationAbstract:A
