Modeling Services
The Thermal Performance Group offers custom modeling services for PEPSE and PMAX.
We can build customized PEPSE models of steam turbine cycles, boilers, gas turbines, combined cycles, HRSG's, cogeneration cycles, and any process plant.
In addition, these systems can be connected to achieve total plant response. Any manufacturer of turbine or system can be simulated. Parametric studies, sensitivity studies, "what-if" studies, degradation studies, test data analysis, and much more may be performed.
Custom PEPSE models include:
- Fossil and nuclear steam turbine cycles
- Gas turbine and combined cycles (including HRSG's and steam turbines)
- Fossil boilers
- Fluidized bed combustors
- Nuclear steam generators
- NSSS
- Co-generation cycles
- Process steam and other process fluid cycles
- District heating systems
- Any fluid cycle
Modifications and enhancementsthat can be made to existing models include:
- Matching test data at any load point,
- Rigorous feedwater heater and condenser calculations (PEPSE's Design Mode and HEI methods), and
- Use of PEPSE's Special Option 6 to analyze test data - various levels of complexity are available depending on your requirements.
Other custom PEPSE services include:
- Using your test data to perform PEPSE analyses and to report results, and
- Building heat balance diagrams to present analysis results in a standard format.
PMAX modeling services include:
- Controllable loss calculations for costs and heat rate impact (fossil)
- Lost MWes calculates Lost Mwes using performance factors (nuclear)
- Steam turbine cycle analysis for steam turbines, MSRs, reheaters, feedwater heater, condenser, and pump performance
- Combined cycle analysis for combustion gas turbines, compressors, and heat recovery steam generators
- Boiler efficiency by ASME Heat Loss or Input/Output methods
- Boiler stage sootblowing advisor provides operators information on where and when to blow soot
- Predictive "What-if?" analysis for turbine cycles and boilers
- Plant optimization
- Cycle isolation assists the user in determining the cost of steam trap and valve leakages
