About Hot air temperature in the wind zone of the generator base

prolonged hot weather events. This information discusses how very high ambient temperatures impact generator performance, service considerations to ensure reliability, and changes that may have to be made to existing generator systems.

This paper focuses on the thermal analysis of a 2 MW wind turbine generator. The goal is to estimate the stator winding temperature with a model as straightforward as possible.

• Generators may be rated on a stand-by basis (see 32.35). Temperature rise not to exceed Table 32-3 by more than 25º C. • For ambient temperature higher than 40º C, the temperature rise shall be reduced by the degrees that the ambient exceeds 40º C. • For totally enclosed water-air cooled machines, the cooling air.

The control system obtains the real-time feedback of temperature and temperature rise data of generator winding and core through the temperature sensor (PT100), determines the start percentage of internal and external circulation fans, and realizes the heat dissipation of generator.

Based on some assumptions and simplifications, a thermal model is developed to describe the heat transfer behavior of wind turbine power system. The numerical calculation method is adopted to solve the governing equation. The heat generation and heat flux are investigated with a given operating boundary.

Can a 2 MW wind turbine generator be thermally analyzed?

This paper focuses on the thermal analysis of a 2 MW wind turbine generator. The goal is to estimate the stator winding temperature with a model as straightforward as possible. Boundary conditions are that no additional sensor than the ones already installed in the wind turbine should be used.

What temperature should a generator be rated at?

Feel free to contribute! Manufacturers guarantee the power of their generators, operating at temperatures of below 40°C. At higher values, derating is 3% for each +5ºC.

Can a gas turbine inlet air cooling system increase power generation capacity?

Mohanty et al. investigated the integration of a gas turbine inlet air cooling system for a 100 MW gas turbine in Bangkok. They showed that reducing the intake air temperature from ambient condition to 15 °C can raise the gas turbine power generation capacity by 8%–13%.
