Wind turbine generator cooling

How to cool a wind turbine?

Through the years challenges of cooling systems for wind turbine caused the new cooling systems. A simple way to cooling the turbine is using the small part of inlet air to the nacelle and filling the needed part and finally exhausting the air from nacelle . These days in MW wind turbines use oil or water for cooling.

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 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.

Do wind turbines need a water cooling system?

Key components in wind turbines, such as gearboxes, generators, converters and power packs, become less effective as they heat up during use. So keeping them at the right temperature is crucial if you want to get the best performance out of your wind turbine. Water cooling systems are pressurised and require a sealed expansion tank.

How Xinjiang wind turbine cooling system works?

The cooling system is connected to the generator outlet through rubber pipes. Fig. 10. Cooling system test prototype. 2.5 MW PMSG permanent magnet wind turbine is the main wind power generation equipment in Xinjiang. The high temperature rise of the generator is closely related to the ambient temperature, unit running time and power generation.

Can a 750 kW wind turbine be cooled?

As to large- and medium-scale wind generating set with power more than 750 kW, a liquid recirculation cooling method can be implemented to satisfy the cooling requirement . Regarding MW wind turbine with a larger power capacity, the gearbox, generator and control converter all produce comparatively large amount of heat .
