Abstract

In December 2011 and July 2012, two sets of 840MVA Hydro-generator of Three Gorges on Yangtze River with Close-Loop-Self-Circulating Evaporative Cooling (CLSCEC) System were put into commercial operation. In this paper, we make engineering summary of these two generators with CLSCEC System. We also make a comparison between the internal water cooling (IWC) hydro-generator used in Three Gorges power plant and the CLSCEC hydro-generator in fields of their operating characteristics, working performances, technical features, working safety and reliability. In addition, engineering structures, type test results and systematic emulating calculation of CLSCEC schemes are analyzed.
