The Research Of WTG Maintenance Management Based On Failure Statistics

With the developing of wind power and large wind turbine generators installation, wind power firms are facing a serious problem that is the maintenance of wind turbine generators.In the operating of wind turbine generators, the depreciation and maintenance costs of equipment are occupied above 85%, So, reduce the maintenance cost and prolong the service life of equipment are the goal of WTG maintenance.In order to prolong the service life of equipment and reduce maintenance costs, paper proposes based on fault statistics maintenance strategy. Through the statistical and analysis of the WTG fault to determine the probability of failure distribution, and then optimize the program of WTG maintenance based on the probability of failure distribution, finally reduce the insufficient or excessive of WTG maintenance. Design a WTG maintenance management system, supported data for the making of maintenance program and real-time tracking the maintenance process.Paper according to the maintenance process and the maintain economic benefit analysis of WTG's gearbox, proved the rationality and feasibility of the thought of WTG maintenance management based fault statistics.
