CONTROL OUTPUT OF GENERATOR TRANSLATION AND ROTATION USING BUCKBOOST CONVERTER FOR SEA WAVE POWER PLANT

Generators are the main components of the power generation system. The generators function to convert mechanical energy into electrical energy by using rotation and translation motion mechanisms. Generator with rotation motion mechanism can be seen on the turbine. While the translation motion generator can be seen in the Pelamis, pneumatic, and other systems. Rotation and translation motion generators consist of rotor components, stators, rotor/stator mounts and more. Performance generator depends on generator drive system, magnet material, magnetic distance, number of coil, dimensional coil and others. In this paper focus on the translation and rotation motion generator mechanism with the drive source in the form of horizontal thrust power (substitute the motion down and up the sea waves). Where the generator output has an unstable voltage so that it cannot be used to charge the battery. To overcome this problem Buck-Boost Converter are used to control output of generator stable. In this research experimental method is applied using a horizontal directional generator mounting structure. Horizontal thrust force is used as the source of the translation of the translation motion generator. The number pole is 4 and 1260 coil winding for translation motion generator. Rotation motion generator using permanent magnet generator with 170 coil winding. The results showed that before using Buck-Boost Converter the output voltage of the translation and rotation motion generators is fluctuated between 18.1-40.14 Volts. After using Buck-Boost Converter, the voltage output of generator become stable at 23.93-24.11 Volts and it can be used to charge the battery.
