ASME PTC 46-2015 PDF

Full title and description

ASME PTC 46-2015 — Performance Test Code (PTC) on Overall Plant Performance. This PTC establishes uniform test methods, measurement techniques, calculations, corrections, uncertainty treatment, and reporting requirements for determining the thermal performance and electrical output of heat‑cycle power plants (combined cycle and most Rankine cycle plants) and for reporting corrected net power, corrected heat rate, and corrected heat input.

Abstract

Provides explicit procedures and formulas for conducting overall-plant acceptance and performance tests for heat‑cycle electric power stations and cogeneration facilities. Applicable to plants of any size when measurements permit accounting for all heat inputs and electrical/secondary outputs at the test boundary. The Code addresses instruments and measurement methods, calculation and correction to reference conditions, uncertainty analysis, and required test reporting.

Scope

Defines uniform test methods for determination of overall plant thermal performance and electrical output for heat‑cycle power plants and cogeneration facilities where all heat inputs to the test boundary and all electrical and secondary outputs can be determined directly or indirectly. The Code covers combined‑cycle plants and most gas, liquid and solid‑fueled Rankine cycle plants; it is not intended for individual component testing (e.g., gas turbines PTC 22, steam turbines PTC 6/PTC 6.2) or for emissions, long‑term reliability tests, or operational demonstration tests outside the explicit test procedures defined in the Code.

Key topics and requirements

• Definition of test objectives, test boundaries and reference conditions.
• Required instruments, sensor types, calibration and measurement methods for key streams (fuel, steam, water, air, electrical outputs).
• Procedures for determining and accounting for all heat inputs and all electrical and secondary outputs crossing the test boundary.
• Calculations for corrected net power, corrected heat rate, corrected heat input and other performance metrics.
• Methods for applying corrections to base/reference conditions and for combining measurements from multiple subsystems (e.g., combined‑cycle configurations).
• Test uncertainty analysis and target uncertainty limits for applicable plant types.
• Reporting requirements and recommended content for test reports, including sample calculations and example appendices (e.g., combined cycle examples).

Typical use and users

Used for pre‑commissioning acceptance tests, contractual performance verification, benchmarking and independent plant performance assessments. Typical users include plant performance/test engineers, owner/operators, engineering consultants, equipment manufacturers, commissioning teams, and regulatory or contracting parties involved in acceptance testing and performance guarantees.
