Modelling the effects of the environment on wind turbine failure modes using neural networks

摘要

Neural networks were used to investigate if any relationship existed between maximum daily gust speed, average daily wind speed and temperature and wind turbine failure modes. Using five years of weather station data a typical site characteristic was determined using the neural network. This was then compared to a characteristic produced using only weather data for days when failures occurred. These failure and normal characteristics were then compared to determine if any relationships existed. It was found that several relationships existed, most notably between gearbox failures and changeable weather conditions.
