Renewable energy has become the most prominent source of energy to reduce carbon emissions around the globe. Undoubtedly, hydro energy is very much clean energy among other sources. In Bangladesh, hydro energy is available only in a specific southern area contributing several hundred megawatts to the national grid. This paper devotes to assessing the capacity and practicability of a hydropower plant to boost the power output by implementing the combined cycle hydropower system. The proposed method has been developed by 1) studying the existing plant based on surveyed data, 2) selecting the site for installing the hydrokinetic turbine, 3) designing with consideration of numerous constraints of inter dependability, and 4) creating a prototype model to ensure the practicability. Preliminary results show that a significant amount of additional electric energy can be generated from the plant with higher efficiency.

Evaluation of water energetic modes of Zhigulevskaya Hydroelectric Power Station is performed. It is found that operating modes are not always strictly in accordance with requirements for maintaining of water level in head water as well as with water discharge in tail water during the period of spring fl ood, summer-, autumn- and winter runoff low. Evaluation results point to the need for review of the Rules of water management. Analysis of real operating modes of Zhigulevskaya Hydroelectric Power Station shows that long-time annual electric energy generation and guaranteed monthly mean capacity in winter period exceed design specifi cation. Stable statistic patt erns of energy indexes and water discharge characteristics are defi ned. These patt erns can be applied for predicting of electric energy generation by Zhigulevskaya Hydroelectric Power Station taking into account climatic water changes.

The article deals with the process of parameters estimation of the flood zone at the dam break or its destruction, and a scale of possible destruction caused by possible emergencies. Modeling is carried out for the time of approach of the breakthrough wave to a given distance, the height of the breakthrough wave, the time of discharge of the reservoir, the duration of the passage of the wave at a predetermined distance for buildings and structures in the area of shock wave. The example is done for the dam of the Middle Dnieper hydroelectric power station. A technique for modeling a hazardous situation related to the consequences of a breakthrough of the dam at the Middle Dnieper Hydropower Plant has been developed. The prediction and simulation is based on the phenomenological parameters of the Kamyansky reservoir.The simulation of the assessment of the engineering environment for the dam of the Serednyodniprovska hydroelectric power station was carried out using the parameters of flooding of the terrain. Parameters used - the possible maximum depth of flooding, the width of flooding and the rate of water flow at the break of the dam, the time of arrival of the wave front, the crest and tail of the break wave, maximal flow dams, wave heights above water level above domestic flow. As a result, the maximum flooded area was estimated.Based on the use of dam and reservoir characteristics and the use of appropriate formulas for calculating emergency factors and using modeling using ArcGIS, the possible topographic consequences of the breakthrough of the dam in the city Kamianske and the locations of industrial enterprises in its vicinity were obtained. The latter enables rescue services to promptly assess the threat of an emergency in the event of an emergency, to have an idea of the consequences in order to take preemptive measures to prevent the occurrence of an emergency.

Abstract Hydroelectric power stations may affect the population dynamics of mosquitoes and sand flies, a group with impact on public health due to the possibility to transmit pathogens to humans. This work characterized and compared the fauna of mosquitoes and sand flies in a hydroelectric power station and peridomicile areas in the State of Minas Gerais, Brazil. Insect collections were performed in August 2015 at dry season and February 2016 in rainy season. Ten HP light traps were set at each of two sites for three consecutive days in each of two seasons (dry and rainy). Furthermore, collections with Shannon traps were made in each sampling area (hydropower plant and peridomicile area) from 4:00 p.m. being shut down at 8:00 p.m. for two consecutive days in each of two seasons (dry and rainy). In total, 1,222 insects from 13 genera and 27 species were collected. The most plentiful species were respectively Culex declarator (Dyar and Knab, 1906) and Pintomyia pessoai (Coutinho & Barretto, 1940). A high number of insects (78.5%) were collected during the rainy period (P < 0.05). About equitability, statistical significance was observed in the peridomicile area (dry season J = 0.75 and rainy season J = 0.82). The highest values of species diversity were observed in the hydropower plant (H = 2.68) and peridomicile area (H = 2.38) both in the rainy season with statistical significance comparing with dry season. Our results demonstrate that the occurrence of vector species in this region increases the potential risk of transmission of pathogens, especially arbovirus and Leishmania Ross, 1903.

The review of the operation, design, and operation features of the mini-hydro power plant that can provide electricity to a private household or a separate private house. A project has been developed to supply the private sector with electricity from a mobile hydroelectric power station. To accommodate the hydropower plant, it was decided to install the DN500 pipeline. The selected water flow rate and the difference in the location of the channel and the location of the turbine installation allow you to provide the required power.The novelty of the work consists of electrifying a private economy using a mobile hydroelectric power station and establishing the advantages and disadvantages of this solution with an assessment of the impact of all design parameters on the output parameters.The research results can be applied for the manufacture of the mobile hydroelectric power station to their usage in the peasant farms, to save electricity, as well as in the development of experimental-industrial samples of electrical installations for various purposes.

In this paper, the hydroelectric power station spillway in local control system is studied. The spillway is one of the most important buildings in reservoir hub, it used for drain the flood which is cant accommodate by planning capacity, and it can guarantee the safety of dam body. It is generally not work. In this paper, the spillway of monitor and control system for a hydropower plant as an example, a method of TSX PLC system of application in local control system was emphatically dissertated, it meets the production demand. The field experience shows the design of the system is reasonable, stable and reliable.
