Development of Riverside Station

In 1910 plans were prepared to develop the Riverside property which had been bought a few years before. This station was opened in April, 1913, the first in mut of plant consisting of two 2,000 K.W turbo-generators and four water tube boilers. Ju 1913 two additional units, each of 5,000 K.W, capacity, were ordered and four more boilers, Again in 1915 a couple of 10,000 KW. machines and one of 5,000 KAW, were ordered together with eight more water tube boilers, Various d Jays due to the war prevented 19,000 KP of this phuit cing into commission at the period it was required, but the other two Machines were put into server during 1917 and also the be ant. The hi demands for electric power which received considerable impetus during the latter part of the war yours made it necess to extend still further the Riverside Station. This was met by the in tion of an 18,000 KW. turbo generator ordered at the end of 1917 and followed by a second machine of the same size which was ordered the next year. In 1920, two 20,000 K.WV. turbines were ordered and also two 3,000 KW. house ice sets, together with the boilers required for pr ducing steam for this plant, which brought the installed plant capacity up to 121,000 The indication recent time K.W,, the present capacity of the Stati

which suysest that an increas? of at least 50,000 K.W. will be needed in the near future, Showinie the volts single phase, 100 cycles, and supplied to aamsumers at 200 volts. When the Fearon Road Station was completely reconstructed, the system of generation and distribution was changed to 3 phase, 50 cycles, and for meeting the growing demands for power supply specially ined transformers were installed for d livering 3 phase current at 6,600. volts. These tranyf iiaately formed the connecting link between the old Fearon Road Station and the new one at Riverside. The Riverside "Station was designed to operate at 6,600 volts, phase, 50 cycles and transmission by underground a cables at 6,600 volts had become the order, but in this connexion it should be noted the pri cipal trunk feeders were laid under-stound this has been the sion at Riverside and in order more economically to transmit electricity over greater distances, the machines have b tied in to step up transformers which raise the generating pressure from 6,609 volts to 22,000 volts. This has been the standard pressure for the underground trunk feoders since 1919, first install tion in China to adopt mocha for fiving the boilers. At the time, a cer ain amount of criticism was levelled the Department because it was imagined that mee 1 stoking could not compete with the so-called cheap Chinese labour. The installation of mechanical stokers proved an entire success and exploded the idea that manually fired boilers, even with cheap labour, was a sound proposition when the size of boilers became wage with each additional was 1,600 K.W.

Consequentl; Department has to operate four 15% steel hopper barges for taking ashes outside Woosuny where they are dumped, In the generation and distribution of electricity, the following sequence of es place: The coal ix brought from the colliers into mechanical ce: handling and conveyed by this into t overhead storage bunkers ors, both of the chain grate and underfeed type, is fed into the boiler furnaces. The steam generated in the boilers is fed into the steam turbines which in turn drive the electric generators. A necessary part of the equipment of each turbine is the condenser for condensing the' exhaust steam into water for re-use in the boilers. At the present time the amount of water pumped from the river for condensing purposes is in the neighbourhood of 160,000,000 gallons per day and it requires over 1,000 H.P. to pump. the water through the condensers, The current generated by the turbine driven generators is next transformed by means of large banks of transformers and thence transmitted to the main 22,000 volt switch ud from there passes through num-be of underground cables to three super testations loc: respectively in the Eastern, Northern and Western districts. These super substations in turn transmit at 6,800 Volts to numerous groups of substations throughout the whole area of supply which, at the time of writing, ranges from the Point at Yangtszepoo up to Hungjao. In these smaller sub-stations the pressure is reduced from 6,300 volts and distributed throughout the low tension 200 volts for I fans and heating.
