Technical Trends on Bearing and Condition Monitoring System in Wind Turbine

Abstract

Wind turbines are generating clean energy and growing rapidly all over the world, but its maintenance cost becomes sometimes very high when failures or breakages occur at drivetrain subsystems. To avoid unexpected or premature failures, special designs of bearings are required for longer life in severe environment on the wind turbines. On the other hand, CMS (Condition Monitoring System) is also used for effective maintenance work through on-line monitoring of the drivetrain parts.
