ASME PTC 46-2015

Overall Plant Performance

This Code applies to any plant size. It can be used to measure the performance of a plant in its normal operating condition, with all equipment in a clean and fully functional condition. This Code provides explicit methods and procedures for combined cycle power plants and for most gas, liquid, and solid fueled Rankine cycle plants. There is no intent to restrict the use of this Code for other types of heat cycle power plants, providing the explicit procedures can be met. For example, the performance equations and test methods herein are applicable to the steam cycle portion of a solar plant, or of a nuclear plant steam cycle. Refer to ASME PTC 47 for power block thermal performance test procedures associated with an IGCC plant (Integrated Gasification Combined Cycle).  This Code does not apply to component testing, for example, gas turbines (ASME PTC 22) or steam turbines (ASME PTC 6 or ASME PTC 6.2) or other individual components. To test a particular power plant or cogeneration facility in accordance with this Code, the following must be met:  (a) a means must be available to determine, through either direct or indirect measurements, all of the heat inputs entering the test boundary and all of the electrical power and secondary outputs leaving the test boundary;  (b) a means must be available to determine, through either direct or indirect measurements, all of the parameters to correct the results from the test to the base reference condition;  (c) the test result uncertainties should be less than or equal to the uncertainties given in subsection 1-3 for the applicable plant type; and  (d) the working fluid for vapor cycles must be steam. This restriction is imposed only to the extent that other fluids may require measurements or measurement methods different from those provided by this Code for steam cycles.
