GE新版燃机基础设计标准理解与应用:动力部分

Comprehension and Application of the Latest Version of GE Standard for GTG Foundation:Dynamic

燃机基础作为燃气发电机组的承载体,其具有良好的动力特性是保证燃气发电项目整体持久稳定运行的重要基础。GE发布的燃机基础设计标准随着燃机技术发展而不断更新。最新的GEK63383g于2018年底发布,在之前版本的基础上做了部分调整。通过对新版标准的解读和对比,总结执行该标准的细节并探讨该标准分析的方法。应用该标准对工程实例进行分析,验证基础的动力特性。

As the carrier of turbine-generator units,GTG (gas turbine-generator) foundation should have good mechanical characteristics,which is an important basis to ensure the sustainable and stable operation of power station.GE is a major supplier of gas turbine,and its gas turbine base design standards have been updated with the development of its technology.The latest GEK63383g was released at the end of 2018,with some tweaks to previous versions.Through the interpretation and comparison of the new version of the standard,the details of the implementation of the latest version of the standard are summarized,and the analysis methods are discussed.An analysis of engineering example is carried out,and the standard is directly used to check dynamic characteristics of GTG foundation.
