Research on sensibility and tendency of rotors to umbalance

Abstract

In this paper are shown results of the research of turbo-aggregate - (steam turbine and generator). There are shown: basic theoretical research of system stability by the Niquist and Bode procedure, turbo-aggregate experimental details with measuring result, research result and their analysis. The goal of research is to evaluate dynamic state, sensibility and tendency of rotor toward imbalance, security function of rotor shaft from a turbine unit part and rotor shaft from part of an electro-unit.
