Are the 2 referring to the same thing?

Appreciate if anyone can share some good resources on the usage of these 2 efficiency in gas-fired power plants.

 

Thanks

thanks for the link.

 

After going through the information, i would like to confirm if my understanding below is correct?

 

1) Rankine Cycle Efficiency = Theoretical maximum efficiency that can be obtained from the steam/water cycle.

2) Isentropic Efficiency of Steam Turbine = Actual Work Done / Isentropic Work Done, where Actual Work Done < Isentropic Work Done

 

Overall efficiency = Rankine Cycle Efficiency * Steam Turbine Isentropic Efficiency, assuming there are no other inefficiencies in the system (e.g. boiler / pump efficiency)
