Failures Provide Valuable Information to Enhance Turbine Availability
A wind turbine is expected to run day and night for 20 years at an availability of 95–98% and only require maintenance every 6 months. As turbines get bigger they also tend to be more complex as a result of optimisations. The cost of having a turbine that is not producing when it is windy is increasing with turbine size. For that reason there is a strong need to identify and implement solutions that will make the turbines run close to 100% during windy periods.
