| TEXT | This plant, a brick building located on an alley near Lincoln and Diversey avenues, was acquired some five years ago by the company and was gradually modified until now there remains only one engine-driven generator, the other electrical equipment of this plant being entirely new. One battery of two National boilers of 75 horse-power each and one of two Standard boilers of 375 horse-power each, furnish more than sufficient boiler capacity for the only remaining engine, a 500-horse-power, cross-compound Buckeye, which is belted to a 500-kilowatt, 3-phase generator.
This generator delivers energy at 4,150 volts delta, 60 cycles, the distribution system voltage of the Commonwealth Electric Company. The generator is really a half of a frequency changing set, similar to those installed in the other substations of the company. A large pulley, belted back to the engine, which plays the part of a motor,
will ultimately be displaced by a motor, and the substation, which at present occupies seventy-five per cent of
the present station building, will be the only occupant. The output of the generators is distributed along with
the output of the frequency changing sets over the same buses, and the two are sometimes operated in parallel. Five hundred volt service is supplied from a small machine, but the load is fast disappearing and is altogether insignificant. Some exhaust steam heating is also done from this plant, for the station is run non-condensing, being remote from both river and rail facilities. Installed in the engine room of the subsidiary steam plant is the substation portion of the plant, which has attained dimensions greater than the steam plant. It is the principal distributing center of the northern district. The equipment of this plant consists of one 1,000-kilowatt and one 500-kilowatt motor generator frequency changing set. These two units operate in parallel on both the 25 and the 60 cycle ends. A 50-kilowatt induction motor exciter set, fed by the transmission line, furnishes exciting current for the two frequency changing sets. The 25-cycle switchboard is installed on a gallery, and the 60-cycle switchboard is on the main floor of the station. This plant is notable in that the first frequency changing set (of 250 kilowatts capacity and since removed) was installed here, and displaced two engine-driven, two-phase generators. |
