The Operation And Maintenance Research Of Offshore Wind Farm Based On Reliability Theory

Offshore wind farm is the direction and tends for the development of wind power in the future. In European countries, the construction and operation in offshore wind farm was very experienced and already formed the scale, but the offshore wind farms are still rare to seen and on exploration stage in china. The O&M stratage of offshore wind farm in china often followed the onshore wind farm mode. But the offhore wind farm is different form the wind farm onshore, it is more complex and harder to repair, the regular inspection and trouble-shooting methods in onshore wind farm can not meet the requirement in offshore wind farm.In this article, according to the characteristices and real situation of the offshore wind farm in china, the works of the O&M were introduced in detail firstly, and then made recommendations of the O&M stratage selection for the offshore wind farm in different type. On the other hand, because the concept of O&M based on reliability was already used on many fields such as aviation industry and its advantages were obvious compare with the traditional O&M concept, the author did lots of research to let this concept applied to offshore wind farm and identify it is meaningful and practical. Then, technical specifications of the availability domestic and overseas were compared, the advantages and disadvantages of time based availability and production based availability were analyzed. In order to prove the O&M based on reliability could bring a lot of benefits in the offshore wind farm, the author estimated the production saving and availability improving after using the O&M stratage based on the reliability of wind turbines based on real datas from an offshore wind farm in domestic to, and made a proposal through SWOT method to apply the O&M stratage based on reliability more quickly and effectivly in this offshore wind farm.
