Attention to Land Reclamation in the Years of Stagnation in the Republic of Uzbekistan

The “Farkhod Hydroelectric Power Station” which was built in Syrdarya region has irrigated 700,000 hectares of fertile land in Dalvarzin and Mirzachul districts of Uzbekistan, Tajikistan and Kazakhstan. “Andijan water reservoir” was built in the Karadarya River of Fergana Valley, and a hydroelectric power plant with a capacity of 140,000,000 kilowatt-hours was commissioned. Due to the commissioning of “Tuyamuyin” waterworks in the lower reaches of the Amudarya River, it was possible to irrigate 300,000 hectares of land in the Republic of Turkmenistan and Uzbekistan, as well as 200,000 hectares of new land for rice and cotton growing. In addition, this water facility has protected the land from erosion and provided with 150,000 kilowatts of electricity.

Purpose. Analysis of environmental problems and risks associated with the construction and operation of small hydroelectric power facilities (SHEPP) in the Ukrainian Carpathians. Methods. Field studies, statistical, hydrological, hydroecological, analysis and synthesis. Results. Potential environmental risks arising from the construction and operation of SHEPP in the Ukrainian Carpathians are considered. The influence of Yavіrska hydroelectric power station on water discharges in the Stryi river was investigated. The daily water discharges for the two hydraulic sections located above and below the station for low-water (2003) and high-water (2008) years are analyzed. Possible risks in the construction and operation of the hydroelectric power plant for the movement of flood waters, river sediments, the development of riverbed deformations, and others, are indicated. The difference in water discharges between the two hydrological stations is presented, and it is confirmed that in the spring of 2008 and 2003 and the autumn and winter of 2003 and 2008 minimal differences in water consumption were observed as a result of the water retention in the reservoir above the dam of Yavіrska hydro power station for the maximal electrical power generation. The impact of the Yavіrska SHEPP on the biota of the Stryi river during 2014–2015 was analyzed. The obtained results indicate that the main negative factors affecting the communities of river hydrobionts are the creation of reservoir of limnethic conditions in the continuum of the river ecosystem; the accumulation of sediments and dead organic matter on its bottom and banks and the demolition of these sediments on the lower sections of the channel bed; also a decrease of water in the riverbed downstream of the dam after the closure of the floodgates in June. The analysis of the environmental impact assessment reports made it possible to analyze the major environmental threats, which are possible during the building and operation of a small hydroelectric power plant on the Stryi river in the Dovhe village (Drohobych district, Lviv region). Conclusions. To prevent the impact of the projected SHEPP in the Carpathian region it is necessary to prescribe the mechanism of carrying out the environmental impact assessment, to specify the natural-geographical, hydrological and hydro-ecological restrictions on the construction and operation of the hydroelectric power station. It is also necessary to identify sections of mountain (“wild”) rivers with high values of natural landscapes and prohibit the construction of small hydropower facilities.

The low resistance of the landscapes of the North-East of Russia to anthropogenic influences is shown. The features of natural plant complexes restoration and land reclamation in the area of the Ust-Srednekanskaya hydroelectric power station are considered. In order to create conditions for the successful restoration of vegetation cover after the impact of anthropogenic factors, it is recommended to carry out measures for leveling the disturbed surface and terracing it. It is proposed to carry out artificial sowing of cereals, which are characterized by regular and abundant fruiting.

In the year of Cheboksary hydroelectric power station’s anniversary, the authors of the article aim to investigate the issue of the waterworks facility’s formation in the early 40s of the last century. Based on the principles of historicism and objective analysis, the main stages of implementing the HPP construction plan are considered. The article presents archival documents which examine the problems of decision-making on the construction of the object. The issue of constructing hydroelectric power stations on the Volga, in particular in the territory of Chuvashia, was studied in the specially created Bureau «The Great Volga». Simultaneously with the construction of Cheboksary HPP, the construction of two more stations – Yaroslavskaya and Balakhninskaya – was considered. The authors present comparative characteristics of the objects. Cheboksary hydroelectric power plant in terms of its performance significantly exceeded other structures. The article notes that prior to the construction of the station, a lot of preparatory and survey work was carried out, which was limited by a tight deadline. As a result of examining the scope of work, material resources and labor costs, the construction of the station was postponed to a later date. Scientists and engineers recognized the priority need to build less powerful stations. The materials of the article can be used for further research of this topic, as well as when writing regional natural history works.

Data Set

This paper presents a procedure based on KDD (Knowledge Discovery Data), which allows the analysis of a data set to obtain structured information from the behavior of the system under specific conditions, such as system failure conditions at a hydroelectric power plant. By applying this procedure, the information obtained, it is structured in such a mode so that it can be used on the training of intelligent systems focused on fault diagnosis. The former procedure is necessary in the intelligent systems development stage because obtaining an effective training set requires extreme time and effort. The procedure was applied in the historical records of the Amaime hydroelectric power plant, located in Palmira, Valle del Cauca, Colombia, aiming to obtain patterns of behavior of the protection system which can be translated to different failures. This was possible by integrating a data mining technique such as hierarchical clustering and the statistical technique called the interpolation function. The main achievement of this work is to present a structured procedure that reduces the time to obtain a training set. In this specific case, the training set for mechanical failure of a hydroelectric power station was obtained, which can be used in the development of an intelligent system for failures diagnosis.

Hydroelectric Power

One of the severe problems of a hydroelectric power plant (HPP) is providing a hydroelectric unit with purified water with the required pressure. Otherwise, the central working bodies - hydraulic turbines - are subjected to abrasive wear and quickly fail. Abrasive wear reduces the efficiency and life of the turbine and causes problems in operation and maintenance. This research aimed to study the degree of abrasive wear (erosion rate) of the surface of a blade hydraulic turbine of a micro HPP during water purification using a hydrocyclone and to ensure its rational layout based on the studies. Investigation of damage to the turbine surface from the dynamic impact was carried out by computer modeling of the process using the Autodesk Simulation CFD program, with different versions of the hydrocyclone body and testing of an experimental sample. Additional software SolidWorks (flow simulation) was used to check the calculations. It was found that the forms of particle hardness in water significantly affect the rate and magnitude of erosion, and a different design of the treatment body in the form of a hydrocyclone in different ways ensures the separation of the flow into phases. A rational scheme for installing a hydraulic turbine inside a hydrocyclone was selected, which provides the required power characteristic of a mini hydroelectric power station and other necessary parameters. The highest degree of water purification from solid impurities (94%) was achieved using the configuration option in a cylindrical-conical design with a rotational water inlet into the hydrocyclone. The location of the hydraulic turbine inside a hydrocyclone of a certain design and the tangential supply of water to the blades of the hydraulic turbine significantly protects the surface of the unit from the effects of solid particles. Their service life can be increased without additional investment in the restoration of the unit.
