Abstract

Abstract: The total length of shaft system of 1000MW ultra supercritical turbogenerator in Huadian International Zouxian Power Plant is 54.652m, and the stability of the shaft system had been tested by too large shaft length. In order to verify the stability of unit shaft system, the load dump test, the oil temperature changing test and the vacuum changing test were down and a series of test data was analyzed, and the stability of the unit shaft was ensured. The results provide reference for optimal design of turbogenerator shaft system.

Key words: long shaft system of turbine, technical parameters, test, stability
