Design and Manufacturing Technology of Fuji Electric’s Large-Capacity, Air-Cooled Turbine Generator
Output of the largest turbine generator manufactured by Fuji Electric is 706 MVA, and hydrogen is used as a coolant in this generator. Based on the design and manufacturing technology of this hydrogen-cooled generator and the advanced technology that had been developed in technical verification testing of 126MVA prototype air-cooled generator built in 1999, Fuji Electric has worked to develop larger capacity air-cooled generator. Due to the R&D with 126MVA prototype air-cooled generator, the design and manufacturing technology for the generators made a great advance. Large-scale fluid dynamic analysis and electromagnetic field analysis were carried out, and the analysis results were compared with the test results and made evaluation. These results were reflected on the design of the air-cooled generators since then. In addition, the latest auto-transposing equipment for the manufacturing process of the generator stator coil, automatic brazing equipment for rotor coil and etc. were developed. This paper describes the features of excellent design and latest manufacturing technology on the large-capacity air-cooled generators.
