SOAPP–CT.25 Version 2.0 Released

Plant Design and Costing Software for Distributed Generation Projects

Chicago, October 1, 2000: EPRI has announced the release of SOAPP-CT.25 WorkStation Version 2.0. The SOAPP-CT.25 software is used to screen opportunities, evaluate feasibility, optimize design criteria, and prepare proposals for distributed generation projects. It helps users design projects for optimal payback, return, and risk mitigation with accurate modeling of site-specific performance and emissions. SOAPP-CT.25 generates detailed plant cost, emissions, and performance estimates, supporting a wide range of gas turbine models up to 25 MW and using current, manufacturer-supplied data. It allows the user to configure the plant to site-specific conditions and requirements and generates detailed plant performance and emissions estimates, equipment lists, project schedule, bill of materials and capital cost estimates, O&M cost estimates, and financial analyses. Additional details and sample output of the new release are available on the web site at http://www.soapp.com/soapp/dg.

New Features in Version 2.0 include:

• Addition of six (6) new Alstom (ABB) gas turbines to the database which brings the total number of gas turbine models to 36. The additional Alstom gas turbines include the following: Typhoon 4.35, Typhoon 4.70, Typhoon 5.25, Tornado 6.70, Tempest 7.70 and Cyclone 12.90.
• Added an input for Evaporative Cooler Effectiveness that is used to calculate the discharge temperature of the cooler.
• Added an input for CT Pressure Loss Method such that the user can select whether the CT inlet pressure loss and CT exit pressure loss is either WorkStation Calculated or User-Specified. If WorkStation Calculated is chosen, the inlet and exit pressure losses are determined based on equipment selections made by the user. If User-Specified is chosen, the user has been provided with additional inputs for CT inlet loss and CT exit loss such that they can override the values calculated by the WorkStation.
• Added an input for CT Auxiliary Power Calc Method such that the user can select between either WorkStation Calculated or User-Specified. If User-Specified is chosen, the user has been provided with an additional input for CT auxiliary power.
• Added an input for Required CT Gas Pressure. This input is used specifically to size the natural gas booster compressor, if necessary. The WorkStation also has an input for natural gas supply pressure.
• Added an input for Duct Burner Firing Temperature. The input was hard-coded at 1600 °F in the previous version. The WorkStation will use this firing temperature when the HRSG Steam Production Limit Switch = No Limit for that particular period. If the user sets the HRSG Steam Production Limit Switch = Limit, the duct burner firing temperature is calculated based on what temperature is necessary to meet the required steam flow (within validation range).
• Added an input for Condensate Pump Sparing. In the previous version, the pump sparing was hard-coded at 2-100%. The user now has the choice of the following sparing options: 1-100%, 2-50%, 2-100%, 3-50%, 3-33%, 4-33%, 4-25% and 5-25%.
• Added an input for Fire Protection System which allows the user to decide if a fire protection system should be included in the design. The fire protection system consists of a 300,000 gallon fire water storage tank and 2-100% fire water pumps.
• Added an input for Maximum Daily Rainfall. This input is used to size the drainage system and the maximum capacity of the waste water treatment systems.
• Added an input for Average Annual Rainfall. This input is used to develop the material balance site runoff flow rates.
• Added several new line items to the CT Performance Report such as Gross Efficiency (LHV), Site Elevation, Ambient Air Pressure, Compressor Inlet Air Relative Humidity, Fuel Type, NOx Control Type and CO Emissions.
• Added HRSG exhaust gas conditions to the HRSG Steam Cycle Summary Report. These new additions display the exhaust gas temperature, pressure, enthalpy and flow at both the upstream and downstream locations for each heat transfer surface in the HRSG.
• Modified the Variable O&M cost calculations. The majority of the changes were in the calculation for Maintenance Inspections.
• Revised the calculation for Condensate Return Flow such that the user can now enter a value in percentage (%) instead of a value in pounds per hour (lb/hr).
• Expanded the Construction Labor Region input to include labor adjustments for all fifty (50) states.
• Modified the Capital Cost Adjustments inputs so that the user can adjust all plant systems.
• Modified the Performance Summary report to display the periodic performance point conditions.
• Improved the economic analyses for average, periodic, and daily levels of detail for both electrical and thermal loads.
• Improved the Quickstart tool for creating new projects, conceptual designs and components.
• Added a user preference to set the heat balance convergence tolerance.
• Improved validation logic to better identify valid and invalid inputs based on the specific design.
• Improved heat balance calculations for duct-fired and external condensate heating (water-to-water heat exchanger) cases.

EPRI’s investment in the frequent development of service releases is an ongoing effort to address user needs and help them to stay current with market conditions.
