Abstract

This research project aims to explore the suitability to start a wind turbine using a commercial alternator known as an Alternating Current Generator (ACG) starter. The ACG starter was used in this project as a wind turbine starter. The study was done experimentally for two cases regarding wind speed. The first experiment, the wind turbine was running for 2 minutes with constant wind speed of 3, 4, 5 and 6 m/s respectively. The second experiment was to operate the wind turbine with varying wind speed in the range of 3-6 m/s for 1, 2 and 3 minutes respectively. The power generating performances for the systems with and without starting system were compared. Using the ACG starter with starting duration of 500 milliseconds was found to extend the power generating duration, regarding the experimental duration. As a result, the greater amount of the total generated electrical power was obtained. The experiment with variable wind speed also found that using the ACG starter provides longer generating period. The maximum power consumption for the ACG starter was found to be about 260 Watts which was much less than the generated power. One can conclude that using the ACG starter to start the wind turbine can increase the amount of generated power. This is especially suitable for the location where wind intermittently flows.
