• Environmental issues around the world have been attracting our attention, and power plants are required to comply with environmental regulations. Turbine generators are also required to increase their output and efficiency to reduce emission of CO_2. To meet these requirements, we have developed a series of indirectly hydrogen cooled turbine generators up to 580 MVA class. Generally speaking, improvement of cooling system and reduction of energy losses are necessary for large turbine generators to increase their output. The latest technologies such as fluid and electromagnetic analyses are applicable to the design of large turbine generators, and we confirmed that they are highly reliable through factory tests of a 510 MVA generator. In this paper, we focus on the state of the art 350 MVA indirectly hydrogen cooled generator developed with 3D fluid and electromagnetic analyses. The efficiency was increased by 0.2% compared to conventional generators.
