Introduction

To determine and/or verify the power, thermal efficiency (heat rate) and/or other performance test parameters of gas turbine driven combined cycle power plants this document establishes guidelines for the preparation, performance, evaluation and reporting of thermal performance tests and describes measurement methods and evaluation methods that take into account uncertainty:

Method of correction of results obtained under test conditions for comparison with guaranteed or specified conditions:

The purpose of the performance test is to determine the thermal performance parameters of the combined cycle based on a pre-signed agreement, such as a purchase agreement, test evaluation criteria rules, general contracting (EPC) requirements, power purchase agreements, power and water purchase agreements, and contractual service agreements:

This document also establishes comparative tests to be conducted before and after a modification, upgrade or overhaul to determine the performance differences between combined cycle and thermal power plants:

test criteria: Combined cycle performance improvements include modification/replacement of major components and addition of components within test boundaries: comparative test the principle can also be used in periodic testing of power stations to monitor the performance aging of the entire power station, taking due account of relevant test uncertainties:

Determination:

Thermal Performance Test of Gas Turbine Combined Cycle Power Plant

1 Scope

This document specifies standards for the preparation, execution, evaluation and reporting of thermal performance tests of gas turbine driven combined cycle power stations and thermal power stations:

Then, the test is carried out at base load or part load, with or without supplementary combustion:

This document applies to:

---General requirements for thermal performance testing;

---According to the contract guarantee, the acceptance test to determine the thermal performance of the combined cycle power station;

--- Comparative tests conducted before and after transformation, upgrade or overhaul to determine the performance difference between combined cycle power plants and thermal power plants:

Within the specified test boundaries, and under specified operating conditions and reference conditions, this document can be used to determine the following thermal performance test objectives and expected value:

---Electric power;

---Heat rate or thermal efficiency;

---Heating steam and/or heating hot water:

This document does not apply to component testing of individual equipment, as relevant standards provide otherwise:

This document does not apply to the following test objectives:

---Environmental testing, such as: emissions, noise;

---Vibration test;

---Run the test;

---Absolute or comparative performance of specific components of the combined cycle specified by specialized standards (for example: gas turbines):
