The Senju (Thermal) Power Station was constructed by the Tokyo Electric Light Company in 1925 as an auxiliary/emergency plant that supplements the needs of the hydroelectric power plants.Since 1929, the company has successfully operated three 25, 000 kVA Turbo-Generators as synchronous condensers at the Senju Power Station. The generators at the Senju Station produce electrical energy for half of the year.
For the remaining half of the year, they are disconnected from turbines and run as synchronous condensers. Used this way, these machines perform double duty. One reason for this arrangement was that the greater capacity of the synchronous condenser was required for the high water season.A second was economic benefits.
After the success of the Senju Station, more than 40 utility Turbo-Generators in Japan were altered for use as synchronous condensers, and others were designed and constructed specifically for this purpose. The use of Turbo-Generators as synchronous condensers was an original development of the Japanese electric power companies.
This note provides an overview of alterations made to the generators at the Senju Station.
