Abstract
The performance characteristics of Autodenki and Generic automobile alternators with the same amperage and voltage capacity were tested to determine their workability as a micro-hydro generator. Both alternators were subjected to preliminary testing using a variable speed electric motor, a belt and pulley transmission system, a charging circuit and two resistive loads supplied by a 12V lead-acid battery which was also used to excite the alternator. The autodenki and Generic alternator produced current at a range of 1000-1400rpm shaft speed speed and 1000-1800rpm shaft speed, respectively. Statistical analysis at α=0.05 level of significance, showed that the voltage and current of both difference but the shaft speed had significant differences. Thus, the Autodenki alternator producing 314.03W is more appropriate to use than the Generic alternator with only 306.94W power output. Actual testing was conducted to know the performance of the two alternators when matched with the micro hydro system. Results showed that the alternator power, turbine and alternator shaft speed were all inversely related and had very strong linear relationship and alternator shaft speed were all inversely related and had very strong linear relationship with respect to the load. The Autodenki alternator has a power output of 22.1W with conversion efficiency of 9.1% while the Generic alternator produced only 21.7W with conversion efficiency of 7.85%. However, there was no significant difference of α=0.05 for the power of both alternators. Thus, using of the two automobile alternators will give the same level of performance when operated in actual conditions.
