Abstract

This paper presents the effectiveness of generator auxiliary system such as seal oil system, stator cooling water system and gas control system with continuous hydrogen scavenging operation for hydrogen-cooled Synchronous Generator at power plant. Effective operation of synchronous generator depends on sufficient cooling medium (hydrogen) inside the casing. Besides that, good sealing system needed to prevent hydrogen gas leakage and sufficient cooling purposes. Deionized water circulated into stator for cooling purposes with emphasized on low conductivity level for prevention of any damage to the copper strands in the stator winding.
