Pico-hydro power generation using dual pelton turbines and single generator

The electricity demand is increasing day by day all over the world. A lot of efforts are made to make the buildings productive and self-sustainable. Due to this fact it is proposed to get energy from overhead water tanks. Following this approach, a 20 m high water tank is considered, water in the pipeline rotates a mini-hydro turbine. The purpose of this scheme is to generate power using low cost mini hydro turbine having negligible environmental effects. The experimental setup of this idea consists of a mini-hydro turbine having a diameter of 0.21 m which is coupled with a dc generator via a chain-gear mechanism to obtain desired rotation. The sensor box is designed to monitor the technical parameters. The calculations and theoretical concepts are presented using basic theory and equations of fluid mechanics and turbo-mechanics, outputs are validated using mathematical and experimental results. This system can replace the ordinary backup units for power generation as it will not consume the power of the existing system for charging batteries.

“…The author reported 130 W generated experimentally at 73 rpm wheel angular compared to 287 W theoretically. A. K.Yahya et al [5] designed a prototype of picohydro generation system that produce low capacity to be used in rural communities. They used two pulley system connecting the pelton wheel and the generator.…”

“…However, the privilege of having natural water resources is not present in every country across the world, a prime example of such case is United Arab Emirates. Also, hydropower has drawbacks in terms of the water quality, wildlife habitats and prevent the fish migration [4][5][6]. To overcome this disadvantage some approaches are suggested such gravitational water vortex power system [5][6][7].…”

Generation of electricity from sustainable and renewable energy sources has captivated the world's nations and became the focus of research and development for the past decades. A need for renewable energy sources to generate electricity, such as solar energy, wind power and hydropower, emerged as fossil fuel resources are not only depleting but also causing detrimental effects to the environment through their emissions and wastes. This paper provides a roadmap to the design process of a hydropower system that generates energy using building wastewater. The underlying theory is explained and tested in a reduced scale real-life prototype. A comparison between the theoretical and experimental results proves the validity of the given theory and design roadmap. The discrepancy between experimental and theoretical flow rates was found to be 13%. The basis of hydropower is to extract the potential energy present in water height difference (i.e. water head). Hence, a real-life reduced scale prototype that utilizes a one meter head of water is designed based on a rigorous set of theoretical calculations. Simulink and ANSYS simulations are used for the design of the Pelton Wheel required for the energy conversion. Based on the solution of the theoretical transient model using Simulink and the ANSYS simulation of the 3D system, the proposed hydropower system was manufactured and tested. Using the test data and the above mentioned theoretical and experimental analysis, the full scale system design is provided using sizing and dynamic similarity which is expected to be implemented in high rise building of various waste water heights

Therefore, the implementation of smaller scale hydropower plant that optimizes the potential energy stored in the descending wastewater in residential buildings, can provide a sustainable energy source for countries that lack the natural water resources.…”
