PROBLEM TO BE SOLVED: To provide a self-excited generator exciting device that makes it unnecessary to alter an air conditioning facility of a turbine building, when replacing a thyristor self-excited generator exciting device. SOLUTION: This device is made of a generator 1 of a power generation plant installed in the turbine building, a main transformer 20 connected to the generator 1 by phase separation bus bars 2 for a generator main circuit, an excitation power supply transformer 3 connected by excitation power supply phase separation bus bars 4 branched from the phase separation bus bars 2, a thyristor 6, a field circuit breaker 16, and a field winding 7 of the generator 1 that are connected in sequence by an AC bus duct 5 connected to the transformer 3, and a cooler 14 that is connected to the transformer 3, which is a water-cooled gas transformer that is installed in the turbine building and that cools gas circulated in the gas transformer. A water path of the cooler 14 is branched from cooling paths 15 of a turbine auxiliary machine cooling water system for cooling the devices in the turbine building. COPYRIGHT: (C)2007,JPO&INPIT
