Development of Linear Permanent Magnet Generator for Wave Energy

This project is about the development of linear permanent magnet generator
for wave energy. Wave energy is one of renewable energy that has a potential as a
source of energy. The objective of this project is to fabricate a linear permanent
magnet generator to be use at the oil platform by attaching the generator to the
platform stand. Currently, the oil platform stands is not fully utilized because it has a
potential for electricity generation by using sea wav. The project begins with
research in wave energy potential and the available methods for wave energy
harvesting. There are four methods available for wave harvesting which are
overtopping sea wave, attenuator, terminator oscillating water column and point
absorber. All of the methods will be analyze to find the appropriate method for an oil
platform application. A proposed design is build based on the chosen method based
from the research. Based on the proposed design, prototype is divided into several
main parts which are rotor, stator and floatation device. Detail steps of fabrication of
the prototype are included inside this paper. Lastly, the prototype is tested to get the
efficiency of the operation and the amount of electricity being generated. Based on
the result of the test conducted, the performance of the generator is analyzed and
several recommendations are suggested for further improvement of the prototype.
This paper is hopefully will attract interest for more research and development of
device for wave energy harvesting.
