“Well, you will be with us in Kolyma - welcome!"How long this phrase had a sarcastic meaning, invariably evoking an unequivocal review:" No, you'd better come to us. " In the past few years it has become fashionable, interesting and exciting to come to the Magadan region. Suddenly, the stunning beauty of the harsh nature, the originality of a small population, opened up, many Russians began to discover a huge Motherland. But the most important thing is that the region began to develop rapidly, not only due to mineral resources, but also as a result of the resources and forces invested in the improvement. Completion of the construction of a cascade of hydropower plants on the Kolyma River will allow the region to attract investment and unleash the full potential of the region.
Ust-Srednekanskaya HPP - large-scale northernbuilding Geographically located on the river Kolyma in the Magadan region. It is part of the Kolyma hydroelectric power station cascade. The object under construction is located 217 km below the existing Kolyma hydroelectric station and is the lower stage of the station cascade. The nearest housing is the village of Ust-Srednekan, which has been abandoned for several years, it is difficult to call it a settlement. For employees and workers built several hostels in the immediate vicinity of the hydroelectric station. Construction is carried out by JSC RusHydro.
Kolyma HPP generates 95% of electricitythe entire region, its capacity is 900 MW. This is enough to meet almost all current needs, but not for development. Ust-Srednekanskaya HPP is designed to increase the amount of electricity generated, which will allow to start the development of local minerals, to build energy-intensive and demanded production enterprises. Its design capacity is 570 MW, the average annual electricity generation is 2.55 billion kWh.
Проект станции был разработан к 1978 году, а construction began in the 1990s. The work stopped at the end of the 90s due to lack of funding. In the subsequent period, money for construction was allocated only from the federal budget, for which an object of such magnitude was very heavy. The resumption of work occurred in 2005 after assessing the financial costs of its construction and the economic effect after launch. The first tranche of financing was received in 2006, which revived the work at the site.
In 2008, the future power plant becameproperty "RusHydro", which was the result of reforms in the company. For the period of construction of the hydropower plant, it became a legal entity of Ust-Srednekanskaya HPP JSC. Work has accelerated significantly, and by 2011 the readiness of the complex was 86%. In September of the same year, the Kolyma River overlapped, which completed the first stage of construction work. At the moment, the equipment is being installed, the construction of the dam and other structures continues.
Magadan region is a harsh territoryclimate, where negative temperatures are observed in late September. Construction work requires a special technology, as they are carried out in permafrost conditions: the ground freezes in places up to 300 meters in depth. The average annual temperature is -12 ° С, the record of January cold is -62 ° С, the average temperature of the middle of winter is -38 ° С. Also, the region is in a zone of high seismic activity.
The capital of the region and the main consumer of energy inthe near future will be Magadan. Ust-Srednekanskaya HPP (the distance to the mouth of the Kolyma River is 1,677 km) will become the main supplier of energy. Around the station, while deserted places, from the federal highway "Kolyma" to the object you need to drive 40 km.
Между двумя станциями каскада река наполняется several tributaries, the total water volume is 4.5 km³. During the warm months of the year, two large floods occur here: in the spring and in the summer-autumn periods. The maximum water flow during the flood period is 17,900 m³ per second (recorded in 1939). In winter, water consumption drops significantly due to climatic conditions and can be no more than 5 m³ per second. Estimated station consumption is 33,300 m³ per second.
Ust-Kolymskaya HPP has a common design solution - it is a dam mid-pressure station. The structure of the facility includes:
Две плотины станции образуют единый водонапорный front. Earth dam poured from a soil mixture consisting of sand and gravel. The priority has a height of 33.5 meters, it creates a minimum working water pressure for the temporary work of the two already delivered hydraulic units.
The second dam of the Ust-Srednekanskaya HPP (325 meters) consists of three parts:
Since the hydroelectric station is built in conditions of eternalpermafrost, then in places where the ground freezes, an impervious filter curtain is laid only after the work on the electric defrosting of the rock. The depth of laying is 25 meters, in places of tectonic destruction the depth can reach 100 meters.
Spillway dam provides water passabout 17200 m³ per second, the discharge is carried out into the water well (length - 168.5 meters, width - 147 meters). The station dam consists of a water intake with four sections. The length of this dam is 96 meters, width is 57 meters, height is 70 meters. The pressure front with the shore connects the concrete dam, the length of which is 105 meters.
In 2011, the river bed was blocked, for which2000 concrete cubes were laid, each weighing eight tons. In 2013, the first two temporary hydroelectric units were put into operation, the expansion of the pressure front and earth dam was continued, and work was underway to prepare for the launch of the third hydroelectric unit.
According to the beginning of September 2016,Ust-Srednekanskaya HPP was completed installation of embedded parts for the third hydraulic unit, the turbine itself is already on the way and follows the train. Turbine disassembled fit in 50 freight cars. Some of its parts have already arrived in Magadan.
The manufacturer of hydraulic engineering is Russian.the company is the Power Machines concern. The power of the water turbine is 142.5 MW. The first stationary hydraulic unit will be installed soon with the skills and abilities of the specialists of the supplier of equipment. Now the station has two temporary hydraulic unit. At the moment there is a concreting site, which will require about 3 thousand cubic meters of the mixture.
Работы ведутся строго по плану, строители they try to do a maximum, as long as the temperature is above zero in the places where the Ust-Srednekanskaya HPP is located. Photos of buildings and the surrounding landscape in stark contrast to each other, demonstrate the power of nature and human efforts to curb it. The launch of the station is scheduled for 2018.
Ust-Srednekanskaya HPP after launch will help solve a number of tasks:
Large-scale construction projects implemented inrecent years in different regions of Russia have convinced even skeptics of the country's ability to solve their problems and increase production potential. A part of promising projects is the Ust-Srednekanskaya HPP. The feedback from the correspondents and ordinary people who visited the site is only enthusiastic. Almost everyone expressed the hope that the Magadan Region and the whole Kolyma Territory will begin to acquire a different story, not so gloomy, based on camp stories.
Reviews about the employer of PJSC "Kolymaenergo"(subsidiary of PJSC "RusHydro") are few. Perhaps because in the Kolyma region with the Internet, things are deplorable. Those who bothered to write a review, talk about both negative and positive aspects of work in the enterprise.
Из негативного основной претензией является не too high wages, which significantly reduces the desire to apply for vacancies, where they will have to work in the conditions of the Far North. Some employees point to a voluntary change in the terms of the contract on the part of the administration of the enterprise, an unfair system of fines, manipulations with the accrual of vacation funds and compensation. The advantages include an excellent team of professionals, established at the construction site. It is difficult to judge from the fragmentary information about the qualities of the employer, but working in extreme conditions is not easy, but because every employee wants normal working and rest conditions.
ПАО «Колымаэнерго» осуществляет набор персонала on the object Ust-Srednekanskaya hydroelectric station. Jobs are open to specialists with a higher engineering education, specialized secondary education, and workers are also needed. It requires hydraulic engineers, IT specialists, shift supervisors, laboratory chemists, divers, crane operators, and so on. The main requirement is an understanding of the specifics of the work of power engineers, specialized education and preferably work experience at other hydropower plants. The company recruits staff not only for the station under construction, but also for the operating Kolyma hydroelectric station.
