Example WEC

To examine the factors involved in specifying a power train, a simplified WEC is investigated. Figure 2.8 shows the simple slack moored heaving buoy introduced in Chapter 1 with hydraulic power take off. It is assumed that the elements of the hydraulic circuit will be mounted remote from the device, probably on the seabed, and that the characteristics of the device match closely those required for resonance at the predominant wave height and frequency. In so doing, the device can be modelled without the use of a control system, giving figures for a power take off system that is less device specific.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
