Does the high ambient temperature affect the power generation capacity of gas turbines?

With high ambient temperature the Top temperature of gas turbine increas resultanly  the load on gas turbine will have to decrease. If the chiller is installed on the gas turbine it will have to put in service to ensure the maximum loading of turbine in high ambient temperatures.

Not luma chora Answer. Simple Derating the load

yes, high ambient temprature affect the gas turbines/engine loss of efficiency

Yes, High ambient temperature reduces the capacity of gas turbines. This can be understood as follows:

High ambient temperature makes the air lighter. This causes less mass flow for the same volume of air, compared to a lower ambient temperature. Hence reduced amount of air will be available for actual compression (low CPD) & less flue gases for further expansion in the turbines. This results in less output.

Yes, the high ambient temp reduces the turbine loading as per oem manual.

high ambient temp affect to trubine and loss the efficiency of trubine

of course it does and it is make restrictions for most of power gas  turbine system

Yes, the ambient temperature is reverse propotionally with power generation capacity that dfenitly will casuse / generate high heat rejection on motor its self....

Yes with high ambient temperature the loading of turbine wuill decrease as per the given chart by the manufacuter of turbine.

It can be seen that the thermal efficiency increases linearly with increases of compression ratio while decreases of ambient temperature. The specifi nt temperature and lower turbine inlet temperature. The effect of variation of SFC is more significance at higher ambient temperature than lower temperature. It is observed that the thermal efficiency linearly increases at lower compressor ratio as well as higher turbine inlet temperature until certain value of compression ratio. The variation of thermal efficiency is more significance at higher compression ratio and lower turbine inlet temperature. Even though at lower turbine inlet temperature is decrement the thermal efficiency dramatically and the SFC decreases linearly with increases of compression ratio and turbine inlet temperature at lower range until certain value then increases dramatically for lower Turbine inlet temperature.
