ISO 2314:2009

Overview

ISO 2314:2009 - Gas turbines - Acceptance tests provides standardized guidelines for preparing, conducting and reporting thermal acceptance tests of gas-turbine power plants. It applies to open-cycle, closed-cycle and semi-closed-cycle gas turbines, and can be used for gas turbines in combined-cycle power plants. The standard defines test boundaries, reference conditions, measurement methods, data handling, calculation and uncertainty assessment to determine or verify power output, thermal efficiency (heat rate) and turbine exhaust energy corrected to standard reference conditions.

Key topics and technical requirements

• Scope and exclusions: covers acceptance testing of complete gas-turbine plants but explicitly excludes emission, noise and vibration testing, component-level tests, auxiliary-system performance, R&D tests and protective/governing system validation.
• Test boundary and reference conditions: defines the measurement boundary and standard reference conditions (ISO 2533 atmosphere) used for correcting results.
• Preparation and test procedure: requires a project-specific test procedure based on the standard and contractual requirements; deviations must be mutually agreed beforehand.
• Instrumentation and measurement methods: describes required instruments, calibration arrangements and handling for flow, temperature, pressure and fuel analysis (gas/liquid).
• Conduct of tests: sets rules for starting/stopping, operating conditions during tests, duration, preliminary checks, data recording and test validity.
• Computation and correction: provides calculation methods to correct results to reference conditions and to compute performance parameters (power, heat rate, exhaust energy).
• Uncertainty and reporting: includes guidance on uncertainty evaluation (Annex A) and example calculations (Annex B); specifies content of the test report. Note: commercial test tolerances are outside the standard and should be contractually defined.

Applications

• Verifying guaranteed electrical or mechanical power output and heat rate during acceptance and commissioning.
• Comparative testing before/after upgrades, overhauls or retrofits (with appropriate project-specific procedures).
• Establishing baseline performance for performance guarantees, contractual acceptance and sale/purchase verification.
• Informing performance modeling for combined-cycle and heat-recovery systems.

Who uses this standard

• Turbine manufacturers and OEM test teams
• Power plant owners, operators and commissioning engineers
• Independent performance test houses and consultants
• Procurement, contractual and warranty specialists managing acceptance criteria
