Modeling and simulation of the Islay wave power conversion system

Abstract

This paper describes the modeling and simulation of the Islay wave power conversion system which is located on the Island of Islay off the western coast of Scotland. A hybrid model of a wave-driven turbine and a grid-connected wound-rotor induction generator is constructed. The generator is modeled such that it retains the actual rotor phase variables but transforms the stator variables only. The model, implemented in Matlab, can be used to investigate under both transient and steady states the behaviors of system variables such as the stator current, the rotor current, and the generated power and torque. Some of the simulation results are presented.
