On the Automatic Hydraulic Power Station.

Abstract

The No. 4th Kawakami-gawa Station, or the automatic hydraulic power station, the pioneer of an automatic station in Japan has been schemed by the Kyushu Dento-Tetsudo, the Toho Elec. Power Co. at present.
The job started on October 1922, and the station was completed on April. The government sanction to operate use has been on the 11th. of May 1923. The generator was made by General Electric Co. and the turbine by Voith Water Turbine Mfg. Co.
In our country, an existing automatic station is the Asahi Power Station of the Bisan Electric Power Company, a sisiter company of the Toho Electric Power Co., but the system of this station is so-called a semi-automatic station with an induction generation which is controlled by the head tank water level by means of the three control wires. While, the No. 4th. Kawakami-gawa Station is entirely automatic station which is controlled only by energizing or de-energizing the transmission line from the main station.
After the completoin, many expart visited the plant with great interest, and then I believe it is not in vain to be read the paper about the automatic station at the meeting of the Institute of the Electrical Engineer by Mr. T. Sato, who has been in charge of designing and erection of the plant.
