ABSTRACT:
There is provided an electric power generating device which includes a generator which is constituted by an interior permanent magnet (IPM) synchronous generator, and is connected to a steam turbine without interposition of a reduction gear, cooling means which flows a liquid coolant used to cool the generator, and a frequency converter which converts an electric power generated by the generator into an electric power at a commercial frequency, and outputs the converted electric power, the cooling means includes a circulation passage to which a tank which is used to store the liquid coolant (oil), a cooler which cools the liquid coolant, and a pump which pressure-feeds the liquid coolant are connected, and through which the liquid coolant circulates, and this configuration enables the generator to operate at a high rotational speed, thereby efficiently utilizing the steam energy.
