The Sayano–Shushenskaya Dam ((ロシア語:Сая́но-Шу́шенская гидроэлектроста́нция, ''Sayano-Shushenskaya Gidroelektrostantsiya'')) is located on the Yenisei River, near Sayanogorsk in Khakassia, Russia. It is the largest power plant in Russia and the 9th-largest hydroelectric plant in the world, by average power generation. The full legal name of the power plant, ''OJSC (Joint-Stock Society ) P. S. Neporozhny Sayano-Shushenskaya HPP (power plant )'', refers to the Soviet-time Minister of Energy and Electrification Pyotr Neporozhny.〔(Microsoft Word – RusHydro_Annual Report.doc ). (PDF) . Retrieved on 2011-06-20.〕 The head of the power plant is Valery Kyari.〔 〕 ==Description== The plant is operated by RusHydro. As of 2009, it was the largest power plant in Russia and the world's sixth-largest hydroelectric plant by average power generation. It provides more than a quarter of RusHydro's generation capacity.〔 The plant operated ten type РО-230/833-0-677 hydro turbines〔(Цхдпнрспахммне ). Sshges.rushydro.ru. Retrieved on 2011-06-20.〕 manufactured at the Leningradsky Metallichesky Zavod, each with a capacity of 640 MW at head. The total installed capacity of the plant is 6,400 MW; its average annual production is 23.5 TWh, which peaked in 2006 at 26.8 TWh. The station's constructions include the dam, a power plant building located near the dam, and an additional spillway which is under construction. The arch-gravity dam is high. It has a crest length of , crest width of , base width of and maximum head of . It consists of a solid left-bank dam long, a power dam long, a spillway dam long and a solid right-bank dam long. It is by far the larger of only two gravity-arch dams in Russia. Water pressure for the dam is approximately 30 million tons, of which 60% is neutralized by the dam's own weight and 40% is carried to rock on the bank〔(Яюъмн-Ьсьемяйюъ Цщя ). Sshges.rushydro.ru. Retrieved on 2011-06-20.〕 The dam is constructed to "safely" withstand earthquakes up to 8 on the Richter scale, and was recorded by the Guinness Book of World Records for the strongest construction of its type.〔(В Книгу рекордов Гиннеса ГЭС просто так не заносят ). Sshges.rushydro.ru. 25 March 2009. Retrieved on 2011-06-20.〕 The dam supports the Sayano–Shushenskoe reservoir, with a total capacity of 31.34 km3, useful capacity of 15.34 km3 and surface area of . 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「Sayano–Shushenskaya Dam」の詳細全文を読む スポンサード リンク
