Hi,
Can anyone help me to understand the followings?
I would like to create a simple thermodynamic model to analyze thermal power plant efficiency without using any online monitoring software’s to make decisions about the operation (controllable lose) and maintenance (overhauling). I want to create the same for Rankine cycle, Brayton cycle, and bottoming combined cycle plant.
As the units mostly expected to run at part load, I have to somehow estimate the expected operational parameter and the losses in heat rate and power due to any deviation of each parameter (Ex: steam temperature, throttle pressure, condenser pressure, attemperator flow, FW heaters etc. ). I can able do such rough estimation at base load with the OEM correction curves as I know the expected value for each parameter from heat and mass balance diagram. How can I estimate any expected parameters at part load with the provided vendor information? I doubt on using the correction curves at part load? Is it still valid to use the correction curves at part load to estimate the contribution of each parameter over all plant heat rate deviation?
It would be really great if someone can clarify this question and provide some references which will give detail insights on this. I think, creating this kind of analyzing model with simple data validation checks in VBA excel might not be difficult. If somebody can share some works/ write-ups which use plant available data to analyze with better relative accuracy over a period would be really appreciated.

The NREL National Renewables Laboratory in USA developed the SAM System Advisor Models software. This program is from September 2017 open source code. Visit in Internet SSC NREL GitHub.
I am colaborating programming the sCO2 Brayton power cycles coupled to thermosolar power plants. I would like to colaborará with you in your project. I am looking for new job opportunity. I finished my Phd in January 2017 and i would like to work for Areva Thermosolar department.
For Brayton power cycles I developed a software in c# and Fortran. This program is available in my researchgate profile. Also the part-load model was programmed in Fortran and Phyton in the John Dyreby Thesis. You could download the software from University of Madison Wisconsin Solar Department.
