Among all kinds of renewable energy, wind energy and solar photovoltaic are the most two important ones in Taiwan. With regard to wind energy, it is disclosed from the government planning reports that wind farm development and the operation & maintenance and standards & design verifications of wind turbine are important issues that should be studied carefully. These issues are related closely to reliability engineering and management. Therefore, it is proposed in this project that reliability engineering be applied to the development of wind power industry. The project covers three-year work. In the first year, environmental data such as wind speeds, ocean wave-heights in certain areas where wind farms are planned will be collected and analyzed based on statistical and reliability methods. Mathematical models that can describe appropriately the environmental data and used in the design of wind turbines will be established. The models will be verified by available real data. In the second year, structural and/or mechanical reliability and system reliability will be studied in consideration that a wind turbine is made of many components such as foundation, wind tower, wind blades, gearbox, gears, rotational shafts and many others. There is also a dynamic reliability problem if one considers the environmental data are inputs to a wind turbine system. Reliability or failure data of wind turbine and its components will be collected and/or analyzed under suitable assumptions. The maintenance means and maintenance periods introduced by foreign teams from developed countries will be investigated to see whether there are rooms for modification in Taiwan. In the third year, based on results of two previous years and in addition to studying wind turbine system reliability continuously, life cycle cost analysis will be carried out for particular wind turbines to see whether the service life of an old turbine can be extended or a new turbine should be constructed to replace it. How the reliability-based design can be incorporated into the design of many onshore and offshore wind turbines will be investigated and discussed as well.再生能源風力發電風機風場可靠度工程與管理可靠度設計壽命週期成本分析。Renewable energyWind powerWind turbineWind farmReliability engineering and managementReliability-based designLife cycle cost analysis.
