Development of Wave-Generation System For Lighted Buoy

Light beacon structures are very essential to the maneuvering of ship especially in the night. The power is usually from the rechargeable battery connected to solar panel which generates electricity from the sunlight. There are two types of structures, one is floating and the other is fixed. In this study, we are dealing with the new power generation system motivated by the wave motion for the floating light beacon. The basic principle of new system is transforming wave motion into electricity by the solenoid that composed of circular tube coiled around and magnetic inside. We succeeded in generating electricity in the lab test using the motion actuator. On the basis of lab test experience it is applied to the real field, Samchuk port. The power unit is installed in the floating light buoy and generating electricity when the inclination of the buoy is beyond the certain limit. The amount of electricity depends on the wave height and wave period. The purpose of field test is to clarify the relationship between the wave condition and electricity.
