燃气轮机联合循环发电厂 - 热性能测试

[中文适用范围]： 本文件规定了由燃气轮机驱动的联合循环和热电联产发电厂在有或没有补充点火的情况下进行基本和部分负荷运行的热性能测试的准备、实施、评估和报告的标准规则。 本文件适用于 — 一般信息的热性能测试， — 确定联合循环发电厂与合同保证相关的性能的热验收测试，和 — 旨在检查联合循环和热电联产电力性能差异的比较测试工厂，用于在修改、升级或大修之前和之后进行测试。 它可用于在规定的测试边界内的特定操作和参考条件下确定以下热性能测试目标和预期值： ——电功率输出； ——热耗率或热效率； ——通过蒸汽轮机处理蒸汽和/或区域供热，但不产生电力输出。 本文件不适用于相应标准涵盖的单个设备组件测试。 它不适用于以下测试目标： ——环境测试，例如排放、噪声； ——振动测试； ——运行测试； ——专用标准涵盖的联合循环特定部件（例如燃气轮机）的绝对或比较性能。 [外文原描述]： ISO 18888:2017 specifies standard rules for preparing, conducting, evaluating and reporting thermal performance tests on combined cycle and cogeneration power plants driven by gas turbines for base and part load operation with or without supplementary firing. ISO 18888:2017 is applicable to - thermal performance tests for general information, - thermal acceptance tests for determining the performance of the combined cycle plant in relation to a contractual guarantee, and - comparative tests designed to check the performance differentials of the combined cycle and cogeneration power plants, for testing before and after modifications, upgrades or overhauls. It can be used to determine the following thermal performance test goals and expected values, under specific operating and reference conditions within defined test boundaries: - electrical power output; - heat rate or thermal efficiency; - process steam and/or district heat w/o generation of electrical power output by means of a steam turbine. ISO 18888:2017 does not apply to individual equipment component testing, which is covered by corresponding standards. It is not intended to be applied to the following test goals: - environmental testing for example emissions, noise; - vibration testing; - operational testing; - absolute or comparative performance of specific components of the combined cycle covered by dedicated standards (e.g. gas turbines).
