SOAPP–REPO WorkStation Version 2.2 Released

Plant Design and Costing Software for Combined Cycle Repowering Projects

Chicago, December 13, 2000: EPRI announced the release of SOAPP-REPO WorkStation Service Release 2. The SOAPP-REPO WorkStation integrates process design, costing, and financial analysis of combined cycle repowering of existing fossil steam plants. This interactive software product supports the analysis of repowering existing coal, oil, or gas-fired boilers with combustion turbines and heat recovery steam generators. From user information the SOAPP-REPO WorkStation configures the repowered plant, sizes and costs the new equipment, and performs detailed performance and financial analyses of the resulting conceptual design. Additional details and sample outputs for the new release are available on the SOAPP web site at http://www.soapp.com/soapp/repo.

New Features in Version 2.2 include:

• Addition of over forty (40) combustion turbines which brings the total number of gas turbine models to 88. Gas turbine manufactures include ABB, S&S Energy Products, General Electric, Hitachi, Mitsubishi, Rolls Royce, Turbo Power & Marine and Siemens Westinghouse.
• Enhanced capability of both the Combustion Turbine (CT) and Steam Turbines Advisors. The user is now able to compare all 88 combustion turbines, including both 50 Hz and 60 Hz machines, in the CT Advisor.
• Improved the validation logic to better identify valid and invalid inputs based on the user’s specific design. Validation logic for the Turbine Backpressure, NOx Emission Limits, and Secondary Fuel Usage Factor were enhanced.
• Modified the boiler feed pump flow calculation which fixed an issue in the project cost calculations.
• Revised the validation of the Capacity Payment ($/kw-yr) and Energy Payments ($/MWhr) inputs to model the entire book life duration within the array.
• Improved the project schedule display so that the user may review Project Summary, Combustion Turbine Generator Detailed Schedule, and HRSG Detailed Schedule reports more clearly.
• Improved readability of Combustion Turbine Performance Results and Equipment List reports.
• Enhanced auxiliary power calculations for repowering cases that utilize the replacement of the cooling tower with a once-through cooling heat rejection system.

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.
