Introduction

This standard is used to purchase gas turbines and auxiliary systems for power generation, and to provide technical support. This standard provides basic specifications for tendering, which are applicable to different environmental and safety requirements, and also regulates the conditions for meeting the requirements. This standard gives basic information for buyers and sellers, such as fuel and other matters. This standard does not cover all of the gas turbine procurement contracts Information, but should include necessary installation information. Especially in the case where the responsibilities of the buyer and the seller can be distinguished, this standard is a technical agreement between the buyer and the seller. The manufacturer has given attention to ensure the applicability of the equipment provided. Due to the different actual operation modes of gas turbines, the performance under the corresponding "standard" operating conditions is also different. Performance in this standard is based on Environmental reference conditions under ISO standards. 􀃽 Requirements for gas turbine applications for power generation equipment

1 Scope

This standard specifies the minimum technical and data requirements for the evaluation and procurement of gas turbines for power generation. This standard applies to land and sea simple cycle and combined cycle gas turbines, as well as cogeneration gas turbines (see (ISO 11086..1996, Appendix B). The test for gas turbine generator sets is also applicable. This standard does not apply to all gas turbines as power propulsion, including aviation aircraft, mobile barges, floating ships and ship propulsion. Into the gas turbines and micro gas turbines used. This standard specifies the requirements for gas turbine ......
