Abstract

Abstract: Aiming at the increase of stator cooling water conductivity of a 300MW heat supplying power generator unit, the reasons of increase of stator cooling water conductivity were analyzed. The problems existed in the stator cooling water system were founded carefully. The improvement measures were formulated. After the improvement measures were implemented, the stator cooling water conductivity was reduced obviously. The method presented in this paper can be used as reference for the same type units to treat similar problems.

Key words: stator cooling water, increase of conductivity, reduce obviously, improvement measure
