Abstract

Energy is an important commodity in our current generation. There are currently many available sources of it, but considering the current decline of the environment's condition one must consider the environmental impact of the energy sources. With this mind set, renewable energy systems are a popular field of study, of which hydro power supply systems are the oldest and one of the most used technology. At present hydro power supply systems are being scaled down to smaller levels to make it more available to more people. Though the endeavor be far from actually attaining perfectly clean energy, it is should be a common goal to improve these systems. One important aspect in improvement is the generator. A Fisher and Paykel motor was converted to a generator and is evaluated if it can be a suitable alternative generator for a 200-W pico hydro power supply system. It was evaluated based on parameters such as voltage, current, power and frequency. From the previous motor ratings the rated speed and other important values were derived. Two set-ups were made to evaluate the generator. The no-load set-up shows that the converted motor behaves much like ordinary synchronous generators but the measured frequency is almost three times higher than the computed oneWhen the generator was connected to a load, it showed that the generator is able to produce 220V at its rated speed, but it is not able to provide 200 W. It was seen from the data that in order to get the desired power of 200W the generator must be ran at more or less 700rpm. The generator in its unmodified form is already sufficient for a 200 W system. But since it produces very low values of current and its measured frequency is way higher than its supposed value, additional installations to the generator such as a frequency converter, voltage regulator and current transformer can be employed to improve the set-up.
