Abstract

The Philippines, as a developing country, is still fossil fuel dependent. Energy generation is one of the major concerns faced by such developing countries. Thus, there is a need to find a solution to this problem. Renewable energy refers to the energy resources that do not have an upper limit on the total quantities to be used. Hydropower, a renewable energy source, converts the mechanical energy in flowing water into electricity. A FiSher and Paykel electric motor was tested and evaluated as a substitute generator for a micro hydropower system. It was matched to an existing test rig and was evaluated based on the input power and the output power. The motor was connected to the set up using a belt and pulley transmission system. Results of the study showed that the belt and pulley transmission used had a % slippage ranging from 11% to 45%. This was accounted in the calculation of the output power of the system. Based on the results, the motor has low efficiency as generator. The maximum output obtained was 57.34 W at its rated velocity, having an efficiency of 11.85%. The optimum conditions for the motor to work as generator, based from the optimization done, were at 140 W load applied with the turbine running at 550rpm and the flow rate at 60 lps.The motor-turned-generator could be improved by considering some modifications of the motor's electrical wirings by changing the type of connection to suit the needed requirements as a generator.
