“…Water energy in various forms, including the seas, oceans, rivers, and even fountains, is as an important source of renewable energy. This type of green energy can be harnessed using multiple technologies such as hydrodynamic screw systems in the direction of water flow or water wheel systems [1][2][3][4][5][6][7][8]. In Fig.…”

“…The hydrodynamic screw also has a linear behaviour in a certain range. The Francis turbines are the most dependent turbines to water level fluctuations [1]. Figure 3 shows the generation of electrical energy through a hydrodynamic screw system, schematically.…”

“…By applying a hydrodynamic screw, even a small stream of water could serve as a source of renewable energy for electrical energy generation. In this way, for each kilowatt hour electrical energy production, about one less kilogram of carbon dioxide contaminates the environment [1]. Being a renewable energy source and causing no pollution for the environment, low maintenance costs, low operating costs and taking advantage of the wasted water resources are among the other advantages of this type of system [1][2][3][4][5][6][7][8].…”

Depending on the volume of incoming water, the hydrodynamic screw speed is about 30 turns per minute; although by applying the gearbox, generator shaft rotation speed increases to 300 rpm which is still w h h hi i lower, its volume increases.…”

One of the most important ways to reduce fossil fuel consumption and consequently reduce greenhouse gases and environmental pollution is the use of renewable energies such as water, sun, wind, etc. One of the most efficient ways to take advantages of the shallow flowing waters such as rivers and fountains in electrical power generation is the use of hydrodynamic screw in the direction of water flow. The design of the generator for this application results in environmental dangers decrease. On the other hand, it provides some part of electrical energy required for human beings. Generators in hydrodynamic renewable energy system ought to have features such as high efficiency, power density and reliability as well as low volume. Among various generators, the permanent magnet synchronous generator (PMSG) meets these requirements very well. In this paper, first, analytical calculations and the design process of PMSG were explained. Then, the ant colony optimization (ACO) was used for the optimization of design quantities. PMSG design optimization increased in efficiency and decreased in volume. By improving these two parameters in the designed PMSG, it gets very suitable to be used in hydrodynamic renewable energy system. Finally, the results of the optimized design of PMSG were validated through simulation of it in Maxwell software and applying finite element analysis (FEA). Also the final results have been compared to similar experimental researches results.

With intentions of preserving cultural heritage and biotic diversity near less technically exploitable Slovenian rivers, plans for sustainable energy production in small hydropower plants are examined. New technologies of water turbines allow the exploitation of ultra-low heads down to 1 m. We have developed a computer program, which makes assessment of energy performance and economic efficiency of small hydropower plant possible. The program has many options from selection of turbine type to variation of number of turbines. Through calculation of efficiency, exploitable flow, net head and other factors, the program calculates nominal power of the power plant and its energy production over a chosen time period. Considering many different conditions we have found out that for power plant in question two units in parallel arrangement of overall nominal power not exceeding 50 kW is preferred solution. Results enable good insight into project viability and thus offer support to investors or sales technicians, while planning investments in hydropower plants on ultra-low head and moderate flow watercourses.
