Abstract

In this paper, we introduce an applied engineering design of Three Gorgespsila 840 MVA hydro-generator with close loop self circulating evaporative cooling (CLSCEC) System and its designing principles. We also make a comparison between the internal water cooling (IWC) hydro-generator used in Three Gorges power plant and the new CLSCEC hydro-generator in fields of their operating characteristics, working performances, technical features, working safety and reliability. In addition, based on the design permanents, engineering structures, modeling tests results and systematic emulating calculation of CLSCEC schemes are analyzed.
