A Review and Methodology Development for Remaining Useful Life Prediction of Offshore Fixed and Floating Wind turbine Power Converter with Digital Twin Technology Perspective

摘要

The growing number of Offshore wind farms demands highly reliable wind turbines to curtail the maintenance cost and to shorten the downtime. Power converter is one of the critical components that undergoes high rate of medium and short term thermal cycles especially in Offshore floating wind turbines compared to fixed bottom turbines. The current study proposes a novel methodology to predict the remaining useful life of an offshore wind turbine power converter in digital twin frame work as a means of predictive maintenance strategy. The remaining useful life is estimated for both diagnostic and prognostic health monitoring specific for offshore operating environment.
