Analysis of pontoon multi pendulum motion response trimaran model at ocean wave power plant based on pendulum system (PLTG-SB)

Abstract

Abstract Ocean waves are one of the renewable energy potentials for an archipelago country like Indonesia. The development of Wave Energy Converter presented in the research carried out is a system that uses a pontoon with a pendulum for energy extraction, which is called the Pendulum System Wave Power Plant (PLTG-SB). The shape of the pontoon uses a trimaran model with a cylindrical shape as the main body and support. The simulation of the response of the pontoon with multi pendulums shows the maximum RAO pitch value of 1.15° / cm in the 6 second wave period and the response to the change in deviation is the maximum value in the 6 second wave period with a deviation of 198.07°. The variation in the length of the pendulum arm gave the largest deviation value of 106.7 cm, while in the variation of the number of pendulums the largest deviation occurred on the pontoon with the number of pendulums n = 2.
