Condition Monitoring of Wind Turbine Gearbox by Vibration Analysis

Abstract

The main aim of this paper is to implementation of condition monitoring on wind turbine gearbox. In condition monitoring we use vibration analysis which is proactive maintenance technique. Condition monitoring is advance and useful tool of proactive technique. Condition monitoring helps to identify the various type of deterioration in wind turbine gearbox. To improve the reliability and performance of wind turbine we apply condition monitoring systems which monitored key component of wind turbine like gearbox. In all renewable energy sources one of them is wind energy. Wind energy is fastest growing energy source in the world. The wind turbine industries still experience gearbox failure, which lead to increase the maintenance and operating cost and also increase cost of energy. To produce wind power more economically it is very important to reduce the downtime of turbine gearbox and improve the reliability. Condition monitoring technique helps to provide necessary information to avoid costly failure, enabling cost effective operation and maintenance practices.
