Description
(54) ПОДЗЕМНАЯ ГИДРОАККУМУЛИРУЮЩАЯ Изобретение относитс к области гидроэнергетики и гидроэнергетических установок н может найти применение при проектировании и строительстве гидроаккумулирующих электростанций (ГАЭС). Известна гидроаккумулирующа электро станци , включающа резервуар верхнего бьефа, здание и подземный резервуар нижнего бьефа, причем резервуар верхнего бьефа выполнен в виде подземной полости, св занной с резервуаром на поверхности земли 1. Недостатком известной установки вл етс необходимость значительного заглублени резервуара нижнего бьефа дл получени высокой экономичности установки и тепловое загр знение окружающей среды при перекачке воды из глубокорасположенного резервуара нижне- бьефа в наземный резервуар. Цель изобретени - увеличение мощности при уменьщении разности отметок расположени резервуаров - достигаетс тем, что резервуар верхнего бьефа выполнен в виде подземной полости, котора заполнена сжатым газом, причем внутренние ЭЛЕКТРОСТАНЦИЯ стенки резервуара верхнего бьефа покрыты теплоизол ционным материалом. На чертеже схематически показана предлагаема установка. Подземна ГАЭС содержит машинный зал 1, в котором установлены гидромашины 2 и электромашины 3. Гидромашины 2 соединены трубопроводом 4 с резервуаром 5 верхнего бьефа и трубопроводом б с резервуаром 7 нижнего бьефа. Полость резервуара 5 заполнена сжатым газом, а стенки резервуара 5 покрыты газонепроницаемой облицовкой и теплоизол ционным материалом . При работе ГАЭС в часы пик гидромашины 2 работают в качестве турбин, а электромашины - в качестве генераторов, вырабатыва электроэнергию. При этом вода из резервуара 5 по трубопроводу 4 поступает на гидромашины, отдает им энергию и отводитс по трубопроводу 6 в резервуар 7 нижнего бьефа. Наход щийс в резервуаре 5 сжатый газ повышает напор на станции , что обеспечивает возможность уменьшить разницу отметок расположени резер(54) UNDERGROUND HYDRO-ACCUMULATING UNIT The invention relates to the field of hydropower and hydropower plants and can be used in the design and construction of pumped storage power plants (PSPP). The known hydroaccumulation power plant, including the upper pool, building and underground lower pool, the upper pool made in the form of an underground cavity associated with the tank on the surface of the earth 1. The disadvantage of the known installation is the need for significant lower pool depth to obtain high efficiency of the installation and thermal pollution of the environment when pumping water from a deep-lying tank to the surface tank. The purpose of the invention is to increase the power while decreasing the difference between the elevations of the location of the reservoirs - is achieved by the fact that the upper pool is made in the form of an underground cavity, which is filled with compressed gas, while the internal ELECTRICAL PANEL walls of the upper pool are covered with thermal insulation material. The drawing schematically shows the proposed installation. Underground PSPP contains machine room 1, in which hydraulic machines 2 and electric machines 3 are installed. Hydraulic machines 2 are connected by pipeline 4 to reservoir 5 of the upper reach and pipeline b with reservoir 7 of the lower reach. The cavity of tank 5 is filled with compressed gas, and the walls of tank 5 are covered with a gas-tight lining and heat insulating material. When the power plant is operating at peak times, the hydromachines 2 operate as turbines, and electrical machines as generators, generating electricity. At the same time, water from tank 5 through line 4 flows to the hydraulic machines, gives them energy and is discharged via line 6 to tank 7 downstream. The compressed gas in reservoir 5 increases the pressure at the station, which makes it possible to reduce the difference in the position
