Abstract

Abstract: The hydrogen humidity of six 200MW generators in Huadian Fularji General Power Plant was out of limits due to the water in oil of sealing oil system, and the operation of the sealing oil system was abnormal due to the larger sealing oil flow. The reasons of the problems abovementioned were analyzed, and combing with practical situation, the relevant improving methods were proposed. Then the security and economical efficiency of generator operation were enhanced.

Key words: hydrogen cooled generator, sealing bush, oil temperature, flow, hydrogen humidity
