초록

Wind turbine, which is attracting part of the renewable energy and is researching continuously, is going to belarge size for high efficiency. There is a yaw system rotating the nacelle, weighted about 600 tons, to beperpendicular with the wind direction blowing in the large wind turbine. The wind turbine is focusing on thereliability improvement because working environment effect is bigger than any other points and specially, thereliability improvement of the yaw drive is required by the customer because it is the key component of thewind turbine. Because of this, the establishment of criteria for yaw drive is required because yaw drive systemis the part of the wind turbine closely related with ensuring the reliability. So, this study did the failure analysisof the yaw drive system, which is consisted with 10 sets of yaw drives through researching and analyzing thesite conditions. Also this study designed the life test method based on the failure analysis and workingcondition of the yaw drive. To design the accelerated life test of the yaw drive, this study reviewed the torque,lubrication condition, and frequency of use and etc. Finally, this selected the torque as the acceleration factorwhich is affected mainly to the system and also, the test equipment was developed based on the requirement ofthe life and performance test.
