Embodiment Construction

[0034] In the following, a detailed description of various embodiments of a wave energy converter will be given. In this description, the term "pool water" should be understood to include any body or body of water. Furthermore, the term "transmission device" denotes a device that converts rotational motion into translational motion, or vice versa, or transmits rotational motion from one part of the system to another. Furthermore, the terms "power" and "energy" can be used interchangeably in some cases, such as "power absorption" and "energy absorption".

[0035] refer to figure 1 , a wave energy converter according to the invention comprises a power or energy absorbing unit 100 (commonly referred to as a "prime mover"), an energy accumulating unit in the form of a power smoothing unit 200, a power generating unit 300 and an accumulator or energy storage device 5, wherein the power stabilizing unit 200 is connected between the energy absorbing unit 100 , the power generating ...

Abstract

A wave energy converter comprises an energy absorption unit arranged to absorb energy generated by movements of water, a power smoothing unit, a power generation unit and an energy storage device, these units being adapted to cooperate to achieve a smooth power output from the power generation unit. The power smoothing unit is arranged to accumulate energy from the energy absorption unit in the energy storage device when the energy absorption unit absorbs more power than the power generation unit generates and to release energy from the energy storage device to the power generation unit when the energy absorption unit absorbs less energy than the power generation unit generates.

Description

technical field [0001] The invention relates to a wave energy converter for generating electrical energy from the movement of water waves, and a method for generating electrical energy from more or less intermittent mechanical energy, such as more or less periodic movements of a body. Background technique [0002] Wave energy is a concentrated form of renewable energy from the friction between the water surface and the wind. The wind over the open sea generates energy, which is then transported closer to shore where it is extracted by a wave energy converter. Due to the high energy density of ocean waves, wave power is very area efficient and the average energy content varies more slowly and predictably than, for example, wind. The resources are large and can be collected near densely populated areas. [0003] One difficulty with harvesting wave energy is that, even within a given sea state, the height and frequency of waves vary greatly. Larger waves contain a sizable po...
