Abstract:

In 2000 and 2005, fish ladders were built in Vilnia and Siesartis rivers providing fish access to another 10 and 25 km of the rivers respectively. The analysis of redd distribution and abundance in both rivers revealed that the construction of fish ladders significantly increased the number and share of redds above dams, however, a significant increase in redds above the dam occurred 2-4 years after fish ladders construction supporting homing behaviour as one of the most important factors for the recolonization of the newly accessible habitats. The tracking of radio tagged salmon and sea trout revealed that statistically, significantly more time, fishes spent in the middle part of fish ladders. Assessed fish ladders efficiency for migrating salmonids made 66%. Minor construction defects and lack of protection were the main factors reducing fishway efficiency. Based on radio tracking data, recommendations are given for minor changes in fish ladders construction and operating schedule to increase the efficiency of fish ladders.

Abstract:

Although Romania has a consistent hydro energetic potential, till now is valuated just approximate 30 percent of it. On the big rivers there are already installed high power hydro plants, but a lot of small and medium rivers are not valuated energetically. Installing a new high power hydro plant tends to affect the zone, being necessary a lot of changes in the environment. The Cross-Flow hydraulic turbines don�t need very complex hydro settlements, being very suitable for small and medium power hydro plants. Also a quite big potential in the use this type of hydraulic machines is the energy recovery in the water treatment and sewage plants. The turbine�s blades surfaces enters in contact with the pressurized water jet. The water jet creates a hydrodynamic force that tends to stress the blade. Mainly the Cross-flow turbine blades are made from steel. This article presents the hydrodynamic design and the possibility of using new polymeric material Delrin �AF for the Cross-Flow turbine runner blades, together with the stress analysis.

Abstract:

Abstract Despite the long history of hydropower technology and rising number of system harvesting energy from alternative sources, the constant research within hydro power sector becoming increasingly important as the power from water was and still is the leading alternative source of green energy generation, capitalized not necessarily within micro-urban structures only. The advantages of hydro systems involve their relatively low acquisition cost against durability, the possibility of gaining energy independence, relatively high flexibility and adaptability for spatial conditions and energy demands of the end users. Nowadays micro hydro systems could capitalize head range starting at 100cm and the efficiency of hydro systems in general ranges between 65-75% in micro and small applications climbing up to 96% in macro designs. It is mostly due to flexibility in applications, adaptability in combinations with other renewable energy systems and the ability to generate clean, stable, thus reliable energy that makes technical development the most vibrant and noticeable in the micro sphere.

Abstract:

This work is within the scope of set of consultancy studies made for Portuguese islands. It focuses on the integration of Pumped Storage Power in isolated islands. The paper starts to address several power systems circumstances about two Portuguese islands on the energetic level. For each of these islands, an independent examination of the conditions to install a reversible hydro power plant is accomplished. Therefore, the energy volume to be stored due to excess of renewable generation and the ideal power and number of the pumps and turbines to be installed were identified and evaluated for the sake of using the produced energy surplus as to be pumped and later generated. The paper enhances the importance of storing energy in the operation of isolated and small systems with considerable amount of intermittent power resources as well as the conditions for the viability of installing new exploitations of this kind.

Abstract:

The exploitation of water flows in collective irrigation networks is promising in view of enhancing renewable energy production in agriculture. To this goal, a simplified method to estimate the electricity production of small hydro power (SHP) plants integrated in existing irrigation systems is proposed. This method schematizes the water network by an “equivalent” system, consisting of a single pipeline with homogeneous diameter and material. The proposed method only requires as input data the altimetry and the maps of the irrigated areas instead of the materials and diameters of all the conduits of a common water network (often unknown by irrigation managers). The feasibility of the proposed method has been verified to size SHP plants in seven collective irrigation systems of Calabria (Southern Italy). This application has highlighted a mean error of 20% in estimating the SHP power with a more detailed model, previously developed by the same authors and verified in the same context; these estimates are more accurate for SHP plants not exceeding 150–175 kW of electrical power. These results suggest the applicability of the proposed method for feasibility studies or large-scale projects of small SHP plants.

Abstract:

The growing demand for electricity forces the humanity to find the most economical methods of its production. Functioning without electricity in today's world deprives human from the possibility of a free existence, and even completely prevents it because of the technicisation of society. Growing awareness of acquiring "clean" environmentally-friendly energy from renewable sources contributes to the successive development of this sector of the economy. The purpose of the article was to analyse the risk of construction costs for small hydroelectric power plants along with an indication of the location and needs of a small hydroelectric power plant in Poland. The subject of the study was a small hydroelectric power plant producing electricity, using a turbine to convert the kinetic energy of water into mechanical energy. Aiming at illustrating the benefits of the discussed investment based on the estimation of construction costs and, as a result, financial results, a specific case of a small hydroelectric power plant located in the region of Kujawsko-Pomorskie [Kuyavian-Pomeranian Viovodeship] in central Poland was analysed. The intended research objective was achieved using industry literature, magazines as well as technical knowledge of persons holding building qualifications (including hydro-technical construction) and materials made available by two Bydgoszcz companies specializing in the implementation of small hydroelectric power plants. TheCOMAR- Jarek Górecki®algorithm, which operates in the industry as the author's concept of calculating the variation of financial outlays incurred for the implementation of investment and construction projects, was used to analyse the risk of costs of a construction project.

Abstract:

At present, in Armenia, hydraulic resources of slow-flowing rivers allow to solve the problem of power supply to small consumers rather efficiently. The electric power generated in small hydropower plants has the lowest prime cost in comparison with that of the power generated by other renewable and traditional power sources. At their construction, in contrast to powerful hydropower plants, the ecological damage (land flooding, destruction of fish farming, the change in the balance of the local climatic condition, etc) are practically excluded. In the present work, issues on applying different types of electric generators in small hydroenergetics are considered. The main advantages, disadvantages and also recommendations on applying electrical generators at their utilization in small hydropower plants are introduced. The developed external damper system for the synchronous hydro aggregate is introduced.

Abstract:

Energy conversion in small water plants with variable speed PM generatorThe Small Hydro Power Plants allow to increase the energy amount from renewable sources, especially from small rivers in mountainous areas. This paper presents a new concept of a energy conversion system for application in a Small Hydropower Plant (SHP) which is based on a permanent magnet generator (PM generator) with a propeller turbine integrated with the generator rotor. The PM generator can work at a variable speed and therefore energy produced by the PM generator has to be converted by means of a power electronic unit to fit to the three-phase power grid parameters. For this concept, dimensions and parameters of the PM generator were specially designed on account of integration with water turbine. The paper precisely describes elements of energy conversion system and also presents the results of numerical tests for chosen working conditions. An original algorithm of control strategy for power electronic unit was used to adjust generated energy to the required parameters of the three-phase grid.

Abstract:

There has been a rapid growth in construction activities during the last few decades owing to overall development in all facets of humanity. Due to technological advancements and ever increasing civilization, there is a persistent need of energy. Along with the conventional energy sources, the renewable energy sources have also significantly contributed to the rising energy needs. As a renewable source of energy, numerous small hydro-power plants (SHPPs) have been built up across the world in the recent past. Usually these SHPPs are being built and operated by the private developers complying with the government regulations. In order to assist a developer in selecting the most profitable and feasible SHPP for construction and subsequent operation, a method based on fuzzy axiomatic design principles is employed in this paper. The techno-commercial and socioeconomic criteria as considered for analyzing the feasibility of the candidate SHPPs are expressed qualitatively using trapezoidal fuzzy numbers. The performance of each SHPP is evaluated in terms of its total information content and the one with the least information content is selected to be the best venture for the required construction activity. The adopted methodology is found to have immense potential to the developers while selecting the most feasible project for construction.

Abstract:

Renewable energy technologies offer the promise of clean, abundant energy gathered from self-renewing resources such as the sun, wind, water, earth, and plants. In this thesis a detailed modeling of hybrid power generation system of solar, wind and small hydro has been developed in Matlab. The simulation includes all realistic components of the system. In this thesis, the power delivered by the combine system component is compa red with each other and various conclusions are drawn. We have proposed a model of 5MW that contains 3MW of small hydro plant, 1 MW of solar plant and 1 MW of wind plant. We have prepared a cost analysis report that indicates it is profitable to go for such model as it satisfies our current and future energy demands. Moreover the electricity generated by the proposed model is available at a very lesser rate as compared to our current electricity tariff rates.

Abstract:

The increased use of renewable energy is imperative as a countermeasure to climate change. As with conventional electricity generation technologies, public acceptance of renewables is an important issue, and willingness to pay (WTP) is a widely used indicator to assess such public attitudes. Unfortunately, the literature to date mostly covers developed countries, with few WTP surveys in developing countries. Tackling climate change is an urgent issue for these developing countries; therefore, understanding of public attitudes toward renewables in developing countries is crucial. This study conducted the first survey on WTP for introducing renewable energy in Myanmar. Although Myanmar boasts abundant renewable energy resources, including solar power and biomass in addition to large-scale hydro plants, its resources are not being properly utilized to generate electricity. This study surveyed WTP for power generation by solar photovoltaics, small hydropower, and biomass facilities. The results showed the highest WTP for solar power (USD 1.92) with 10% share in the energy mix, and lower WTP for biomass and small hydropower electricity generations (USD 1.13 and USD 1.17, respectively). Careful public communication is thus crucial for expanding biomass and small-scale hydro power plants.

Abstract:

The prospects for the use of solar power plants in the world of environmental hydraulic engineering are analyzed. Recommendations on the constructive combination of elements of structures of environmental hydro technical complexes with solar photovoltaic installations (SFEU) are presented. The variants of their most rational location on the building of hydroelectric power stations (GES) of different types are considered. It is established that the buildings of small and medium-sized hydroelectric power plants represent significantly more constructive possibilities for combining the GES building with the SFEU. The relationship between the area suitable for placing solar cells and the diameter of the turbine impeller is determined. With a decrease in the diameter of the impeller, the relative surface area suitable for placing solar cells increases. It is noted that it is most appropriate to combine SFEU and small hydroelectric power plants with non-combined buildings with transformers on the downstream side. At medium-sized hydroelectric power plants of various types, the conditions for combining are approximately the same. The results of the work can have an impact on obtaining a reliable power supply system based on renewable energy sources, improving the safety of the GTS (hydro technical structures) of existing hydroelectric facilities in the context of increasing the efficiency of the introduction of ”green“ technologies in the energy sector while reducing biosphere pollution and greenhouse gas emissions, including in hard-to-reach areas of agricultural areas where there are problems with centralized water supply.

Abstract:

The dependence of power plants on energy sources such as diesel, natural gas and coal is almost 75%, encouraging the development of renewable energy in an effort to meet the electricity supply. One of them is the micro hydro power plant by utilizing the potential of existing water. The working principle of PLTMH is to change the potential energy of water into electrical energy. In this final project has been designed modeling of micro hydro power plant by using screw turbine (Archimedes Screw). The turbine used resembles a drill bit, with a diameter of a turbine of 26 cm, a screw width of 10 cm, and an amount of 10 pieces of blade. Measurements made on the modeling of micro hydro power plants include: water discharge, turbine rotation, generator rotation, voltage, current, torque and generator output power and efficiency. The parameters are measured by changing the water fall on the turbine from the position of the turbine head angle 00, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 700, 800 and 900 . The result of measurement that has been done on the parameters of micro hydro power plant modeling, obtained the highest measurement result at the corner of turbine head 400. The output power generated is 10.92 watts, torque is 0.60 Nm and efficiency of 14%. The results obtained are still low because the turbine rotation is less able to rotate the generator, where the generator torque is greater than the torque in the turbine. This is influenced by the small water discharges in the modeling of this micro hydro power plant.

Abstract:

In terms of generation capacity, Victoria has about 12,500 MW, out of a National Electricity Market (NEM) total of over 46,000 MW. A bit over half of Victoria’s capacity is made up of the brown coal generators in the Latrobe Valley (Loy Yang, Hazelwood, Yallourn). Gas-fired generation (mainly large open-cycle peaking plants, designed to operate only in times of high demand) and hydro plants (mainly parts of the Snowy scheme) add about 20% each, with wind currently making up the balance of around 9% of installed capacity in Victoria. In terms of wind farm location across the NEM, installed capacity is predominantly located in Victoria and South Australia, and to a lesser extent in Tasmania, with very small amounts in New South Wales and Queensland. This distribution is almost entirely due to the quality of the wind resource across the country.

Abstract:

Hybrid hydro energy systems are usually analysed with pumped hydro storage systems, which can facilitate energy accumulation from other sources. Despite the lack of water storage, run-of-the-river hydropower plants are also attractive for hybrid systems owing to their low investment cost, short construction time, and small environmental impact. In this study, a hybrid system that contains run-of-the-river small hydro power plants (SHPs), PV systems, and batteries to serve local loads is examined. Low-power and low-head schemes that use variable-speed operation are considered. The novelty of this study is the proposal of a dedicated steady-state model of the run-of-the-river hydropower plant that is suitable for energy production analysis under different hydrological conditions. The presented calculations based on a real SHP of 150 kW capacity have shown that a simplified method can result in a 43% overestimation of the produced energy. Moreover, a one-year analysis of a hybrid system operation using real river flow data showed that the flow averaging period has a significant influence on the energy balance results. The system energy deficiency and surplus can be underestimated by approximately 25% by increasing the averaging time from day to month.
