Q1: what standards are used ?

EPro+ is based on internationally recognized standards and reference data to ensure accurate and repeatable performance calculations, including:

 

  • ASME PTC 22-2014 – Energy balance and mass flow calculations.
  • ISO 2314:2009 – Gas turbine inlet temperature calculations.
  • NIST Chemistry WebBook (SRD 69) – Thermodynamic property reference data.
  • NASA Glenn Research Center Thermodynamic Coefficients – Species enthalpy and specific heat calculations using fifth-order polynomial representations.

EPro+ applies ideal gas assumptions for gas turbine working fluids, providing a robust and reliable basis for gas turbine performance assessment and optimization.

Yes. EPro+ evaluations are routinely performed remotely using a proven process developed by AIM Power Consulting. Our team provides remote oversight and guidance throughout the evaluation, working closely with onsite plant personnel to ensure proper test preparation, data collection, and measurement point execution. This approach enables accurate and reliable performance assessments while minimizing travel costs and operational disruptions. The resulting insights can support targeted gas turbine optimization services and improved gas turbine efficiency.

EPro+ was specifically developed for gas turbine technologies that utilize ISO 2314 methodologies for turbine inlet temperature evaluation and is compatible with a wide range of industrial and aeroderivative gas turbines.

EPro+ also supports turbine technologies that utilize alternative turbine inlet temperature definitions. While OEMs may define turbine inlet temperature differently, the underlying thermodynamic principles remain the same. EPro+ accounts for these manufacturer-specific differences through tailored thermodynamic models and correction methodologies, enabling accurate and consistent evaluations of gas turbine engine performance, including compressor and hot gas path condition, as well as overall gas turbine performance across multiple turbine platforms.

EPro+ was developed to minimize testing durations while maintaining data accuracy. Unlike traditional approaches that rely on fixed heat-soak periods, EPro+ performs real-time thermodynamic calculations, including mass flow, turbine operating conditions, and other key signals, to determine when a unit has truly stabilized.

By using criteria-based stabilization rather than time-based assumptions, EPro+ can materially reduce heat-soak and measurement durations, allowing units to be returned to normal operations sooner while supporting efficient gas turbine optimization.

Preliminary results are available in real time during testing, enabling immediate review of unit performance. Final reports are typically issued within two weeks following completion of testing and receipt of all required data.
