Faults Analysis of Double Water Inner Cooled Synchronous Machines

Abstract

In the power system, the large-capacity double water inner cooled turbine generators and synchronous condensers occupy a certain market share. Their normal operation is the key upon the safe and stable operation of the power system. Therefore, mastering the faults types, faults causes and faults characteristics of the double water inner cooled synchronous machines is of great significance for ensuring their safe and stable operation and reasonable arrangement of operation and maintenance. Based on the structural characteristics of the double water inner cooled synchronous machines, this paper studies mainly the common faults locations and types of synchronous machines, the causes and characteristics of the faults, the physical quantity to be monitored, etc., which provides a reference for the maintenance and repair of the synchronous machines.
