Abstract: This paper presents power estimation and reliability evaluation of the micro hydro power generation system based on municipal waste water. Self-excited induction generator was used in the developed power plant, situated at IIT (BHU) campus, Varanasi, India. The hydro potential of the waste water flowing through sewage system of the Banaras Hindu University has been determined for annual flow duration and daily flow duration curves by ordering the recorded waste water from maximum to minimum flows. This paper estimates output power and determines reliability indices like: failure rate, repair rate, MTTF, MTTR and MTBF of the MWW-based developed generation plant. Design parameters of the SEIG with suitable values of the capacitor have been used and recommended for improvement of the power generation quality and reliability of the system.
Keywords: micro hydro power generation; reliability indices; flow duration curves; failure rate; repair rate; mean time to failure; MTTF; mean time to repair; MTTR; mean time between failure; MTBF; self-excited induction generators; SEIG; power estimation; municipal wastewater; India.
