2003 2005 2007 2009
• The project start to develop a software to help energy auditing procedure.
•Five expert under guidance of Dr. Khosravy work on that research project.
• First version of commercial software developed and branded under name RPA (Rey Performance Auditing)
• During 2005 to 2007 RPA sold and used by more than fifteen plants.
•Along this period the second project started in RIPI to enhance former software.
• The second version under brand EPAT released.
•Two plant buy customized version of this software.

Boilers and HRSGs
Steam Generator Module provides a heat balance diagram of the steam generator, which determines heat input, heat output, heat losses, heat credits, and overall boiler efficiency based on ASME PTC 4 .0 and 4.4.The efficiencies of the energy conversion and transfer process have direct relation to deterioration due to equipment and operational problems. Early identification of the cause of poor boiler performance allows affective preventative actions. EPAT’s assessments identify potential energy and cost savings.

Steam Turbines
Steam Turbine Module determines key performance indicators of the turbine that provide plant personnel with a comprehensive picture of the turbine condition. All the calculations for key performance indicators are based on industrial standards (ASME PTC 6s).Component of steam turbines varies corresponding to the design of the plant. Typical components for steam turbine are: HP turbineLP turbineIP turbineDeaeratorFeedwater heaterElectrical generator

Gas Turbines
Performance deteriorates against time is a normal phenomenon for all machines including gas turbines during operation. The deterioration results in loss in power output and increase fuel consumption. The subsequent impacts such as lower production and higher operating costs will effect negatively on company’s revenue and profits. Thus, accurate assessments of the capability and operating conditions of the GT are essential.EPAT provides performance monitoring under varying ambient conditions, based on industrial standards (ASME PTC 22) and Performance Test Reports from Machine Manufacturer.

Compressors
Studies on turbo machinery’s life cycle costs have shown that energy costs normally far outweigh the procurement, installation, and maintenance costs. This has led to an increased awareness of the values of efficiency, capacity flexibility, and performance analysis and monitoring, in addition to the traditional values for reliability.All the calculations for key performance indicators are based on industrial standards (ISO 5389 and ASME PTC 10), as well as Performance Test Reports from Machine Manufacturer.
