Abstract—This paper describes an alternative energy source: municipal waste water for micro hydro power generation. Reuse of municipal waste water can be a stable, inflation proof, economical, reliable and renewable energy source of electricity. A micro hydro photovoltaic hybrid power generation system has been designed, developed and practically verified to provide reliable energy to suitable load in the campus of the Institute of Technology, Banaras Hindu University, Varanasi (Uttar Pradesh) India. The hydro potential of the waste water flowing through sewage system of the university has been determined for annual flow duration and daily flow duration curves by ordering the recorded water from maximum to minimum flows. Several factors such as design pressure, the roughness of the pipe, interior surface, method of joining, weight, ease of installation, accessibility to the sewage system, design life, maintenance, weather conditions, availability of material, related cost and likelihood of structural damage have been considered for design of a particular penstock for reliable operation of the developed MHPS. Output power has been estimated for available different head and flow rate of the waste water. Various types of the turbine-generator sets for different available head have also suggested for reliable operation of the developed MHPS. Self excited induction generator has used and recommended for reliable operation the MWW based MHPS.
Index Terms—Municipal waste water, flow-duration curve, self excited induction generator, sewage system, system reliability.
