Study of the Thermodynamic Processes and Performance Evaluation of Self-Circulation Evaporative Cooling System in Hydro-Generator

Abstract:

The self-circulation evaporative cooling system (SECS) of stator collector ring is a kind of new cooling technology, utilizing the evaporating of work fluid to cool the stator collector ring of hydro-generator. In this article, the thermodynamic processes of SECS of stator collector ring were analyzed by the second law of thermodynamics. The entropy production and power loss of isolated SECS were analyzed. Based on the distinctive characteristics of SECS, a performance evaluation function was proposed. The influence of heat load on was discussed by simulating. The conclusions provide the theory basis for the application of this new cooling technology.
