This paper presents a comparative analysis between the double-feed induction generator (DFIG) and directly connected squirrel cage induction generator (SCIG) when they are used in a wave energy conversion system. Simulation results are presented to illustrate the operating ranges of the asynchronous generators and the generated power by the system. The simulations are developed and implemented in...
In this work, a hydraulic turbine speed governor is proposed in view of its application in an isolated electric generation system based on an ocean wave energy converter (WEC). The proposed strategy is based on cascade closed-loop control combined with feedforward of load disturbances. The main characteristics of a WEC are presented and a dynamic model of the generating unit is developed. Experimental...
This paper considers the problem of optimizing the efficiency of the primary conversion on an ocean wave energy hyperbaric converter. This wave energy converter (WEC) is an oscillating-body linked to a hyperbaric chamber. By solving the equation of motion of the power take-off mechanism, it is shown that optimal conditions for improving the absorbed power relate the buoy parameters and the chamber...
