Spencer Street Power Station was a Victorian era coal and (later) oil-fired power station which operated on Spencer Street in central Melbourne, Victoria, Australia. Opened in 1892, it was closed in 1982 after becoming redundant. Eventually deemed an eyesore, demolition commenced in 2006. ==History== Spencer Street Power Station was built by the City of Melbourne to supply electricity to the city. Arthur James Arnot designed and managed Spencer Street power station from 1894-1901 for the Melbourne City council.〔(Biography - Arthur James Arnot ) - Australian Dictionary of Biography〕 A Station:- The first power plant consisted of 24 General Electric direct current (DC) generators installed in four groups of six. Each group was belt driven by a 300HP Austral Otis horizontal compound slow speed steam engine. The terminal voltage was 3KV DC and the electricity was used for street lights, trams, lifts and city buildings. Steam was supplied from four Babcock and Wilcox water tube boilers. In 1897 four General Electric 75KW alternators were added. They were belt driven by the existing engines. Output was 2KV and 72 Hz. In 1900 a Peach three-crank compound 2500HP steam engine was installed. It was coupled to a Johnson & Phillips 120KW alternator. The alternating current (AC) was used in the surrounding suburbs via transformers. 1905 saw further expansion with one 200KW alternator, 4x350KW vertical Belliss steam engines that were direct-coupled to DC generators at 460V DC. This was to augment the city supply. Steam was supplied by another four Babcock boilers.〔One Hundred Years of Engineering;Electricity Supply in Victoria; E.Bate Bsc AIME〕 In 1907 the first turbines were installed, with two 750KW British Westinghouse Parsons 4.4KV single-phase machines added. The old arc lighting plant was removed to provide the space. 1908 saw three Allen triple-expansion engines installed, each coupled to 750KW generator and more boilers. A Siemens 4.4MW 6.6KV three-phase alternator was added in 1913. Next year, two William Robinson 5MW turbo-alternators were added. 1917 saw a further addition by way of a 6.5MW turbo-alternator from British Westinghouse. This was a three-phase, 6.6KV 50HZ machine, and ran at 1500RPM. In 1927 four 6MW three-phase 6.6KV turbo-alternators were installed. At this time all the DC generators were replaced with AC generators.〔Early Electric Supply in Melbourne;Miles Pierce〕 By 1923 there were a total of 20 Babcock water tube boilers, each having a steam capacity of 17,000 lb/hr at 165PSI and 520degF. Smoke was directed into two smoke stacks each 175 feet high. B+C Stations:- In 1949 two 15MW Parsons turbo-generators were installed in an adjacent site. Steam was supplied by large oil-fired water tube boilers. Ten years later two 30MW Parsons machines were added and called C station. Steam was supplied by more water-tube boilers that were fitted with pressurised fluid equipment, but for pollution reasons were only oil fired. In 1941 the station came under the management of the State Electricity Commission of Victoria and became part of the state electricity network. Progressive upgrades saw the capacity of the station rise to 109 MW by the 1960s, but newer power stations in the Latrobe Valley meant that the station was retained for peak use only. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spencer Street Power Station」の詳細全文を読む スポンサード リンク
