Abstract:

The Performance Assessment of Wave and Tidal Array Systems (PerAWaT) project, launched in October 2009 with £8m of ETI investment. The project delivered validated, commercial software tools capable of significantly reducing the levels of uncertainty associated with predicting the energy yield of major wave and tidal stream energy arrays. It also produced information that will help reduce commercial risk of future large scale wave and tidal array developments.

This report provides a characterisation and assessment of the availability of tidal resource at example sitees across the UK. The analysis is extended to show the change in the local flow field by considering the M2 tide, which is representative of an average tidal cycle occurring in the UK waters. It is not intended in this work package to evaluate the optimum array configurations to generate the maximum power ateach site. This work package mainly focuses on developing and applying an elaborate numerical scheme for predicting maximum power that is available to arrays of turbines, modelled as momentum sinks using Linear Momentum Actuator Disk Theory.

In this report we have modelled the inclusion of tidal turbines at a headland site (Anglesey), an estuary site (Bristol Channel), and a strait (Pentland Firth). Similar methodologies have been successfully applied to the various different sites. The available power has been analysed at all sites and the hydrodynamic effect of including turbines analysed. It is found that when significant power is extracted there is a substantial change to the current at a site, but that the hydrodynamic changes are confined to vicinity of the site
