“…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.…”

“…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.…”

“…According to the above description, the generator that is going to be used in this application should have features such as high efficiency, power density, reliability, and small size and volume. A permanent magnet synchronous generator (PMSG) is one of the best choices with the ability to achieve the above purposes [1,[4][5][6][7][8]. In [1] it was explained that the use of low speed PMSG for small hydropower plants has made the electrical energy generation economical by new production methods.…”

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.

Challenges Facing the Implementation of Pico-Hydropower Technologies

840 million people living in rural areas across the world lack access to electricity, creating a large imbalance in the development potential between urban and rural areas. Pico-hydropower offers a cost-effective way of accessing electricity, where the resource exists. This paper discusses and critically examines several challenges that remain in implementing pico-hydropower systems, such as local manufacturing, maintenance and repair of turbines, low-head solutions, dealing with variation in the water flow between seasons, the ability to deal with income generating loads and low system power and capacity factor. The solutions to many of these problems exist; several low head turbine systems are appearing on the market, and new power electronic packages are able to improve the system capacity factor. Some turbines are now being designed for local construction using design for manufacturing rules, so only basic workshop tools and process are required to build turbine systems and components, and enabling turbines to be locally repaired. Through the commercialisation and implementation of these solutions, the proliferation of pico-hydropower systems can take place providing low cost sustainable electricity for remote communities, but this requires a stronger emphasis in social awareness and policy. Three critical enabling factors for the success of pico-hydropower projects are identified through this analysis: understanding the local context, financial sustainability and stakeholder awareness.
