PLANS FOR THE CONSTRUCTION OF THE CHEBOKSARY HYDROELECTRIC POWER STATION IN THE 1940s

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.

Nowadays, energy demand is considered a notable world problem. The purpose of this study is to define, document and finally select an option of only one renewable energy source system, as to which is considered the most suitable solution from an environmental, social and economic point of view, for the energy independence of Zakynthos Island in Greece. This study examines the following alternatives; Biofuels Production Station, Geothermal Power Station, Hydroelectric Power Station, Solar Power Station and Wind Power Station. In order to determine the optimal renewable energy source, a multi-criteria decision-making approach is followed. The three pillars of sustainability, namely, the environment, the economy and the society, were used as the primary criteria in the context of the under determination goal. A significant number of environmental, economic and social sub-criteria were also developed and were subject to weight evaluation using both pairwise comparison and evaluation through structured interviews. Results, with regard to the delimitations set for the scope of the current study, indicate that solar energy source system is the optimal sustainable alternative.

ABSTRACT Cerrado is the second largest biome in Brazil and is classified as a biodiversity hotspot. The establishment of hydroelectric power stations in Brazil originated degraded areas due to the removal of soil for construction of dams, in which native vegetation sometimes fails to reestablish due to the bad soil conditions. Sheep excrete most of the nutrients they ingest, such as phosphorus, calcium, potassium and nitrogen. This study aimed at investigating whether sheep dung contributes to the improvement of soil quality and stimulates the process of ecological succession in areas affected by the construction of the hydroelectric power station of Ilha Solteira. Four areas were selected, located at the Experimental Farm of Unesp Ilha Solteira/SP, and ten plots of 1 m2 each were established. From October 2014 to December 2015, five replicates received 150 g fresh sheep dung every 15 days. In December 2015 soil sample from top 0.10 m was collected for the determination of soil attributes. Aboveground biomass was also collected, separated into four functional groups, oven-dried and weighed. Data were analysed to check the effect of dung addition upon soil and vegetation variables. Dung addition stimulated the development of several functional groups and changed soil nutrient concentrations in all four studied areas.

The Impact

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 article discusses the features of the linguistic expression of the concept of a hydroelectric power station (HPS). The material for the study is the data of etymological and encyclopedic dictionaries, special educational literature, as well as data obtained during interviews of workers of various Russian hydroelectric power stations, and data from a linguistic experiment. The process of research revealed and described: etymology of the name of the concept; conceptual features of the concept; figurative layer (through the analysis of metaphorical names); evaluation layer of the concept. It has been established that the concept of hydroelectric power station (HPS) refers to gestalt concepts, since it is a conceptual system that combines different types of concepts. The professional linguistic picture of the world of hydropower is characterized by the conceptualization of the conceptual categories of «living – nonliving», «simple – complex», «natural – man-made». The axiological layer of the professional concept is poorly expressed against the background of the conceptual and figurative layers.

Presently, however, Hydroelectric is a source of power that can prove to be available to all, regardless of conditions such as weather. As history showed, a lot of development, as well as alterations, were made to this efficient supply of energy. Hydropower is a positive alternative energy source that nature provides, therefore, its effective usage is not prohibited. Although there are many disadvantages associated with the design and construction of a hydroelectric power plant, the advantageous features are even more enormous. This paper deals with construction and design aspects for the implementation of the small hydroelectric power station. The main parameters can be collected from the site. Then the turbine type and dimensions can be specified. The generator specifications,which is the main part in the system, for hydro-power stations can be obtained from the determination of turbine output power. These specifications involve mainly the rated power in KVA, the type of system, system frequency, the type of stator winding connection, rated load voltage, rated load current, load power factor, generator speed, method of the system cooling, and the generator type of excitation.
