4 FAQs about Normal generator wind temperature range

What temperature should a wind turbine operate at?

During the meeting, CTUIL representatives explained that the IEC 61400-1 standard, which applies to wind turbines, sets the normal operating temperature range between -10°C and +40°C, with an extreme range of -20°C to +50°C. They discussed whether the reduced efficiency of turbines at 40°C should be considered when determining grid connectivity.

Can a wind turbine be rated at 40°C?

The Power Ministry has instructed that wind power plants with WTGs operating at rated output at 40°C and having no de-rating of capacity below 40°C will be compliant with normal operating range of the International Electrotechnical Commission (IEC) standard. De-rating a wind turbine means operating it at lower power than it can deliver.

Should wind turbine generators be considered when determining grid connectivity?

The Ministry of Power has instructed that Wind Turbine Generators (WTGs) that operate at full capacity up to 40°C, without losing efficiency, in line with the IEC 61400-1 standard, should be considered when determining the extent of grid connectivity.

What is the normal temperature range for a petrol generator engine?

The normal temperature range for a petrol generator engine is between 70°C to 90°C. Temperatures above 90°C or too high can reduce the efficiency of the gasoline engine, resulting in reduced power and increased fuel consumption.
