Climate Condition and Gas Turbine Output
The climate condition in Thailand is high temperature and performance and power generation of Gas Turbine combined cycle power plant are affected by the climate.
Yearly ambient temperature and humidityGas Turbine power generation
Gas turbine in Thailand can not achieve the rated output by high temperature.
