Historical background. In November 1979, on the Vilyui, a tributary of the Lena, below the first and second stages of the Vilyuiskiye HPPs, preparatory work for the construction of HPP-3 began, and a few months later (January 10, 1980), a the Construction Department of VGES-Sh was created. The head of the construction department was approved by a hydraulic engineer who passed the school of Bratsk and Ust-Ilimsk, Vasily Ivanovich Voropai. Five kilometers from the alignment of the future hydroelectric power station, at the site of the planned construction camp and industrial base, in the taiga, the first peg was hammered. Then the brigade of O.I. Khareva started building a dormitory for 60 people. The team of hydroelectric builders of the Vilyuiskaya HPP-3 was staffed with people who came here from hydroelectric power plants, which by that time had been completed or were being completed: from the Vilyuiskaya HPP-I-II, Ust-Ilimskaya, Kureiskaya, Sayano-Shushenskaya, Nurekskaya, Toktogulskaya. The construction project for the Vilyui HPP-3 was approved by the USSR Council of Ministers in 1984. At the same time, the examinations and conclusions of the Hydroproject Institute, the USSR Ministry of Energy, the USSR State Committee for Science and Technology, and the USSR State Construction Committee recognized the absence of analogues in the world practice of hydropower construction. Taking into account the particular complexity of geotechnical and permafrost conditions, novelty of design and layout solutions, peculiarities of organizational forms of construction, Vilyuiskaya HPP-3 is classified as a unique facility. The construction area of the hydroelectric complex is located within the central part of the Siberian platform, in the zone of permafrost. The thickness of the frozen rocks ranges from 50 to 100 m at the sides of the valley and up to 300 m at the watershed. The foundations of the dams are non-rocky permafrost rocks with ice content from 10 to 40, and in some areas with basalt cryotexture - up to 60%. Vilyuiskaya HPP-3 with an installed capacity of 360 MW (4 units of 90 MW each) and an average annual power generation of 1.2 billion kW / h is of great national economic importance and is intended to provide electricity to the diamond complex of the Russian Federation (ALROSA), to develop new deposits of diamonds, gas, oil and socio-economic development of a group of Vilyui regions of Yakutia. The station is equipped with PL-40/800/87850 turbines manufactured by the Kharkov Turbine Plant, Sibelektrotyazhmash generators, transformers of the Zaporozhye Transformer plant. ” During the construction of the hydroelectric complex, new approaches to solving a number of technical problems were required. permafrost non-rocky foundations, brown concrete "Walls in the ground". Research has been carried out in other areas as well. Decisions were taken by specialists from Lenhydroproject, Vilyuygesstroy, and the Construction Department of Vilyuiskaya HPP-Sh. The settlement of hydro-builders Svetly is one of the most beautiful villages in Yakutia. It appeared on the map of the diamond edge in 1984. The settlement for the builders of hydroelectric power plants and operators was conceived with the allocation of sites for capital and temporary development. The capital part consists of 5-storey large-panel residential buildings of the "Arktika" type, series 1-464 of the "Indostroyproekt" Institute with improved apartment layouts, closed outboard balconies and an attic roof. The number of the city-forming group of construction and operational personnel was, respectively, 3040 and 190 people. In addition, the hydroelectric builders have erected all the facilities of the industrial base required for the construction of the hydroelectric power plant, engineering facilities, and quarries. The industrial base includes a concrete and processing facility with two concrete plants, a base for prefabricated reinforced concrete and large-panel housing construction, a motor pool for 310 cars, a mechanization base, and other auxiliary services. Cargoes are delivered to the construction site by rail to the Lena station - the Osetrovo river port, then along the Lena River 950 km to Lensk and 314 km by road. Part of the cargo is delivered by aviation to Mirny airport. The construction site of the Vilyuiskaya HPP-3 exists in a capital design, with its own engineering support and a base village. In August 1993, the construction of the Vilyuiskaya HPP-3 and the village of Svetly were consecrated by the Russian Orthodox Church. In 2001, the construction of the Church of the Vladimir Icon of the Mother of God began in the village of hydro-builders and was commissioned in 2004. In 2000, AK ALROSA acquired 66% of the shares of Vilyuiskaya HPP-3 OJSC. Vyacheslav Anatolyevich Shtyrov, the then president of ALROSA, made the decision, which was fateful for the Vilyui hydro-builders. Thanks to the real support of the ALROSA management, the construction site received a second wind. The main stages of construction of VGES-3: - start of work on the main structures. The first explosion was carried out by the Bratsk department "Gidrospetsstroy" (head of the section VP Gordeyuk) on April 22, 1983; - the overlap of Vilyui and the passage of expenses through the construction canal was carried out by teams of motorists and machine operators, headed by BC Trenin and A.G. Tkachenko on October 6, 1986; - laying the first cubic meter of hydraulic concrete in the building of the hydroelectric power station; it was produced by V.I. Mikhailov on April 22, 1987; - installation of the impeller of the first unit was completed on May 23, 2001. This was done by the specialists of Spetsgidroenergomontazh, led by the senior foreman E.E. Televitsky. - return of the Vilyui river to its original channel - July 23, 2002; - The first hydroelectric unit was launched and put into operation on September 8, 2004; - the start-up of the second hydroelectric unit and its commissioning was carried out on December 22, 2005; 2. Brief description of the Svetlinskaya HPP. 1. Location. The hydroelectric station is located about 80 km (by road) from the town of Mirny, 100 km. from the village of Chernyshevsky and 141.2 km along the river from the Vilyui HPP-1,2, on the territory of the Mirninsky district of the Republic of Sakha (Yakutia). The area of the construction site includes the village of Svetly, the industrial zone and the territory of the main structures. 2. Purpose of the waterworks. The Svetlinskaya HPP with an installed capacity of 360 MW (4 hydroelectric units of 90 MW each) with an average annual electricity generation of 1.2 billion kWh is intended for power supply to industrial consumers in the Western Energy Region of the Republic of Sakha (Yakutia). The development of the diamond mining industry in the West Yakutsk industrial region causes a rapid increase in energy consumption 3. Capital class of the main structures - II. 4. Features of the waterworks. The hydroelectric power plant is being built in unique geological and climatic conditions. Annual temperature fluctuations reach 100o (from plus 36o to minus 63o). The construction area is located in the zone of permafrost non-rocky soils up to 300 meters deep. Within the building of the hydroelectric power station, the soils are in a thawed state, and under the soil dams on the left-bank and right-bank dams - in a frozen state. In the practice of hydraulic engineering, this is the only case. Another feature of the Svetlinskaya HPP is the compactness of the structures of the HPP run-of-the-river building, which is combined with 16 bottom spillways of complex configuration, located under the spiral chambers of the units and under the installation site. To the left and to the right of the HPP building, the pressure front is formed by the left-bank and right-bank stone-earth dams with a length of 112 meters and 273 meters, respectively. The maximum height of the dams is 64 meters. The dams are dumped onto frozen shores, after which electric defrosting and cementation of the foundations of the dams and the building of the hydroelectric power station are performed. 3.
