“…Direct energy from the immediate ocean environment may be of particular interest for remote or isolated ocean applications since the local wave energy source is persistent, predictable, has a high power density, and maintains a minimum power level in most ocean environments [1]. This work extends the previous research for axi-symmetric, heave-only, power absorbers [2,3,4,5] and implements finite element analysis (FEA), with active control, driven by spectral waves that are present in the real world. In the previous work a two-body, slack-moored autonomous WEC (AWEC) system had been designed and analyzed, but just with monochromatic waves [6,7,8].…”

Wave Energy Converter (WEC) design strives to produce as much power as possible across differing wave conditions. It is especially true of autonomous WECs (used, for example, to power an ocean buoy sensing system) because they are smaller and they need to maximize the amount of power produced under minimal wave energy conditions. This is because the electrical power required is considered a constant load. Autonomous WECs (AWECs) also tend to operate near shore where the wave spectral content spans a larger frequency range. This paper describes the type of spectral waves to be used during the design and simulation stage, then presents results from the WEC hydrodynamic finite element analysis (FEA) that uses integrated optimal control with both monochromatic and spectral waves. A comparison is made of these results against a SPICE simulation using a twobody equivalent circuit. Using these results, plus integrating the effects of losses in the power take-off (PTO), conclusions are reached regarding the preferred control method. It was found that damping control may be the preferable control scheme for this application.

This paper illustrates the status of wave energy development in Pacific rim countries by characterizing the available resource and introducing the region's current and potential future leaders in wave energy converter development. It also describes the existing licensing and permitting process as well as potential environmental concerns. Capabilities of Pacific Ocean testing facilities are described in addition to the region's vision of the future of wave energy.

“…The sea wave motion is transferred to the linear generator, via a cylindrical floating buoy that is fixed on the translator of the machine [4]. The arrangement of the electromechanical system for the sea wave energy extraction with the use of a linear permanent magnet generator, is shown in Fig.1.…”

The paper presents the design procedure and the modelling of performance for a special coupled electromechanical system, for use in sea wave energy extraction applications. The system is consisted of a specific linear permanent magnet generator combined with a cylindrical floating buoy moving due to the sea wave incidence. The system analysis requires particularly developed electromagnetic -mechanical -hydraulic simulation models. The proposed models suitability has been checked through measurements in a 16 kW prototype power plant.
