Design and simulation of a hybrid solar and wind water pumping system for Busitema university.

Abstract

This thesis presents the design of hybrid solar wind turbine system for pumping underground water for Busitema University by utilizing both solar and wind renewable energy to reduce on the high costs of pumping water and' inadequate water supply to students. The study was started by investigating the potential ability of both solar and wind energy in the desired location which is Busitema University where the metrological data, mean, wind speed and monthly solar irradiance of global radiation horizontal' were analyzed. The system was optimally designed for an average of 1000stúdentswith water requirement of 60000L/day. turbine was simulated to analyse for static pressure, turbulence intensity and stress distribution exposed at 1.5m/s wind speed. The A cost analysis was done to estimate the total project investments maintenance and overhead costa annual net income stream and the payback period. The simulation results showed that the system could effectively operate at speeds of 15m/s without deformation. The net cost value of project is 24859000 UGX with a payback period of 4years.The study will, therefore, be a useful guideline in making investment decisions -in hybrids since the system is estimated to have minimum lifetime of 20years.
