Rankine Cycle backwards calculation

[fleppen]

Hello Together,

we are running a Biomass Powerplant and I want to simulate it in DWSim. I have been trying around with a rankine cycle simulation and it works fine so far. My goal is to determine the turbine outlet pressure dependin on the cooling power of the condenser.
Looking into the turbine block there are following options for the calculation method: Outlet Pressure, Pressureloss, Electricity Production, Energy Stream, Known Head, Performance Curves, Pressure Ratio. (Some freely translated from German). I dont have the performance curves of our Turbine.
Which of those Methods do you recommend? In My eyes none of them makes sense. Maybe the Energy Stream, but when clicking on it the calculation method stays "Outlet pressure"

Would be great to get a hint!

Greetings,
Leo

Hi Dan, without knowing your model it is challenging to define what is the best parameter to be used.
Anyway my suggestion is to use the pressure ratio. Lower pressure ratio, higher pressure and lower power generated.
