Heat exchange system diagram of wind turbine generator set

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.

What is waste heat in a wind turbine?

Generally, every large wind turbine has a cooling system and a lubrication heater. So, for ensuring normal operation heat exchange rate between gearbox and cooling fluid must be sufficient. The next section of waste heat is generator rotor. The generator rotor is connected to gearbox and rotate in high speed.

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 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.

How does a generator heat exchanger work?

The circulating fan extracts the hot air inside the generator through the pipeline into the heat exchanger of the device, and the external circulation fan sends the cold air outside the cabin to the heat exchanger for hot and cold exchange.

How does a permanent magnet wind turbine cooling system work?

The measurement and control system in the cooling control cabinet of the permanent magnet wind turbine cooling system uses Siemens PLC as the control core. The PLC processes the signals collected by the sensor and monitors the generator cooling system in real time.
