Failures and Maintenance of Wind Turbines Marwa Ibrahim

Wind turbine reliability depends on the reliability of some key components. Maintenance of wind turbines is conducted twice a year at 6-month intervals. Typical maintenance would involve a thorough inspection of the entire system, replacement of fluids, lubrication, and servicing of mechanical parts. There has been an increasing focus on reducing the cost of wind power, particularly operating and maintenance (O& M) costs, which include day-to-day operations, preventive (scheduled) maintenance, and unscheduled maintenance due to unexpected failures of wind turbine components.
