Abstract

In a country where there is enough power to distribute, people start to think alternative way to reduce the monthly electricity bill by manipulating natural resources as alternative energy such as wind and solar to generate electricity. However, both systems are not suitable for all areas and locations. Hence, this project is conducted to develop a small scale hydro generation system using consuming water distributed to houses as an alternative electrical energy source for residential use. Water flow in the domestic pipes has potential to generate electricity for energy storage purposes in addition to the routine activities such as laundry, cook and bathe. The inherent water pressure and flow inside the pipe from utility's main tank that used for those usual activities is also used to rotate the hydro turbine to drive the mechanical shaft. This mechanical power is then being used to drive a generator in order to generate electrical power. Extensive study on generator types, turbine types, pipelines, fittings and valves is the core part of this research. This is to ensure the system that being designed and developed, theoretically, has efficiency at the highest possible. Then, once the system is fabricated, performance tests are necessary to determine the real efficiency of the system compared to the theoretical one. Results of the performance tests show the feasibility of the system or indicate possible action for improvement in the future. In general, the performance analysis shows that the project product able to generate electricity up to approximately 1.2W DC. This amount of power is very small and relatively suitable to supply small loads such as LED lighting and for battery charging purpose as a mechanism of energy storage. Thus, examples of application of the system are mobile phone battery charging, toys battery charging and energy storage future use of small loads at home such as LED lighting. It is therefore, this system which is termed as "Pico-Hydro Generation System" is very useful during blackout. It is also another alternative from various products in the market for household to save energy bill consumption although in a small amount. However, there are rooms for improvement to increase the system efficiency.
