Digital Twin
PEPSE is a Windows-based, drag-and-drop, steady-state energy balance software package that is sophisticated, yet easy to learn and apply. It allows the user to simulate a modular representation of a plant’s thermal processes including component hardware and piping systems. Plant performance is then calculated through the user-created schematics that mimic your plant’s thermal operation and configuration.
When engineers have the ability to readily and accurately analyze and optimize a system’s efficiency, the operation derives a number of direct and important benefits.
PEPSE is the key to:
  • Accurately analyzing plant performance and identifying ways to increase generation and reduce your fuel cost
  • Eliminating causes of inefficiency and conserving every possible kilowatt and BTU
  • Reducing plant emissions and carbon footprint
  • Lowering your operating costs through higher efficiency, fewer repairs, less downtime and lower fuel costs
  • Granular modeling provides confidence in the accuracy of plant assessments of proactive decisions
PEPSE has a number of different modes, allowing its use as a tool for conducting a range of studies:
  • Compare actual data to expected values
  • Evaluate the system affects of changes in operating arrangements, in performance indicators, or in individual component modifications
  • Analyze test data as specified in ASME® performance test codes
PEPSE provides engineers with integrated performance data and the means to construct detailed system models for evaluating heat rates and plant performance.
The functioning of controllable parameters in a plant – equipment condition, system interaction, steam operation, gas and other fluid systems – all contribute to its overall efficiency.
PEPSE has been installed in over 700 generating units over the past 40 years and is the industry standard in thermal performance monitoring.
PEPSE is the advanced computational tool for easy and accurate analysis
In addition to evaluating overall plant performance, PEPSE will let the user perform a host of other important tasks. Additional ways to employ PEPSE include:
  • Isolate individual component performance – pinpoint specific hardware malfunctions before they escalate and create costly systemic problems
  • Evaluate potential design modifications – before new systems or equipment investments are made
  • Determine desirable cycle heat rates for new nuclear, fossil, or combined cycle units or for changing fuel sources
  • Audit NSSS, boiler, heat exchanger, feedwater heater, condenser, HRSG, or turbine vendor (steam or gas) claims during a proposal evaluation
  • Perform “What-If” analyses to determine effects of operational changes and conducting plant degradation studies, plant data reductions, and incremental heat rate calculations.

PEPSE provides integrated performance data and the means to construct detailed system models
PEPSE can be readily employed to test any part of your plant system: hydraulic parameters, equipment hardware, cycle piping arrangements, component characteristics, and ambient conditions. With this ability to monitor a full range of operating variables and conduct a comprehensive assessment, the power to affect overall plant efficiency increases.
Easily and accurately analyze your entire plant, a portion of the facility, or individual components
PEPSE may be used as both a standalone program or in a network environment. It also allows interaction and data transfer and results between other software programs such as PEPSE-RT, Excel® and Visual Basic®.
