摘要
近年来世界风电高速发展,2009年中国的新装机容量已位居全球第一,总装机量居全球第二。但是我国风机的正常工作时间和发电量都和装机容量不成比例,远低于世界平均水平,因此,开展风机可靠性研究,提高风机的可靠性,从而减少故障率和维修成本刻不容缓。阐述了世界与中国风力发电的状况,探讨了风力发电机可靠性研究的理论基础以及研究手段。
In recent years wind power is developed rapidly all over the world.In 2009 the newly installed capacity in China ranked number one,and the total capacity took the second place in the world.However,the normal working hours of wind turbines and the amount of power generating capacity are out of proportion and far below the world average.Therefore,study on reliability of wind turbines is necessary for improving reliability of wind turbines and reducing failure rates and maintenance costs.This paper introduces the overall situation of wind power development both at home and abroad,and discusses the theory of reliability of wind turbines and methods for improving reliability.
