In 2007, the National Renewable Energy Laboratory (NREL) which is an agency under the U.S. Department of Energy set up the gearbox reliability collaborative (GRC) project. it has a budget support of $US 2.5 million to find the causes for damages to gearbox. This project has been ongoing for several years and in 2010 GRE world request for an additional $US 2.5 million to finish the project. 67 Figure 14 Wind Technology Illustration [16] Research and Development on Wind Energy Technology Most research and development in Thailand focus on identifying wind energy potential with mathematical models or through the use of measuring equipment. The research on wind energy technologies that should be considered by researchers in Thailand covers the following issues; Moreover, in order to ensure that a gearbox meets the standards required prior to installing it onto a wind turbine, the gearbox will be tested at full power. It will then be monitored for vibration and noise during operation, as well as the temperature of its lubricant and the working of the gear’s cogs in order to confirm that the design standards are met. At present there is no production of a gearbox for wind turbine. There are only factories that assemble the gearbox with imported parts for other industries. The technology related to power generation with wind turbine is presented in Figure 14.
