6 FAQs about [Wind turbine gearbox cooling]

How do wind turbines maintain gearboxes?

Conclusion This study was prompted by a maintenance issue that a wind turbine operator in southern Morocco had with maintaining the wind turbines’ gearboxes. They have been maintaining the gearboxes by simply cooling them down automatically whenever their temperature reaches a critical prespecified threshold.

What is wind turbine cooling?

Wind turbine cooling involving: wind generator, electronic and electric equipment, gearbox and other components cooling. Through the years challenges of cooling systems for wind turbine caused the new cooling systems.

How long do wind turbine gearboxes last?

AWEA. While wind turbines are designed for a lifetime of around 20 years, existing gearboxes have exhibited failures after about 5 years of operation. The costs associated with securing a crane large enough to replace the gearbox and the long downtimes associated with such a repair affect the operational profitability of wind turbines.

What is the optimal policy for a wind turbine gearbox?

It has then been made possible to determine the optimal policy (N*, P*) for any given wind turbine gearbox with a given reliability, operated in any specific situation in terms of costs related to maintenance, logistics, cooling, and production loss.

What happens when a wind turbine gearbox is replaced?

Then, after a number of cooling actions during which the wind turbine operates under capacity resulting is a loss of energy production, the gearbox is replaced by a new identical one or submitted to an overhaul. The renewal time is based on the maintenance agents’ personal judgement.

How a wind turbine cooling system works?

In this study, a conceptual design of a new wind turbine cooling system is proposed. In this system, the heat which is generated by wind turbine using a coolant comes to ORC cycle and gives the heat into the refrigerant. After that the coolant goes back to the wind turbine to take the heat.
