Short Term Deterministic Wave Prediction as a Tool for Enhanced Performance with Survivability for Wave Energy Converters.

进行可行性研究，以提高海浪能量转换装置的平均输出，并结合确定性海浪预测（而不会增加海浪损坏转换器的风险）。这项工作将探索在所谓的静息期（发生在可能损坏转换器的大波之间）操作波能转换器的操作和收益。在大波间隔期间，变流器将与波系统解耦，从而将结构负荷降低到安全水平。由于关闭所需的时间有限，需要几秒钟的前向波预测。此外，还将研究利用波浪预测来控制变流器内的自适应动力元件对能量输出的影响，以便实时优化每个传入波组的性能。将有三个阶段：(i)研究在静止间隔内运行的能力所带来的收益，与如何识别这些论文无关；（ii）明确研究波浪场应用及其性能的确定性波浪预测；（iii）整合前两项研究，以评估结合实际波浪预测系统的性能能力可实现的收益。除了可行性研究中通常负担得起的论文和模拟工作外，关键的新科学要素（主要是预测方面）将成为实际实地研究的主题。这是有可能的，因为拟议的项目属于新的半岛海洋和可再生能源研究所（PRIMARE），该研究所与商业西南波中心相连。该项目将进入PRIMARE波浪和电流传感器网格，该网格是一个距离北康沃尔20公里的3公里乘4公里海域的密集仪器，与一组商业波浪能转换器的地点相对应。

To carry out a feasibility study of the enhancement in average output of wave energy converting devices that is possible with the incorporation of Deterministic Sea Wave Prediction (without increased risk of wave damage to the converters). The work will explore operation of and benefits from being able to operate wave energy converters in the so called quiescent periods that occur between large waves that could damage the converter. During the large wave intervals the converter will be decoupled from the wave system so lowering the structural loading to a safe level. Foreward wave prediction of a few seconds is required due to the finite time required for shutdown. Furthermore work will be undertaken on the effects on energy output of using wave prediction to control adaptive dynamical elements within converters so as to optimise the performance in real time to each incomming wave group. There will be three phases: (i) a study of the gains stemming from the ability to operate in quiescent intervals, independent of how theses are identified, (ii) a study of deterministic wave prediction explicitly for wave farm applications and their performance and (iii) an integration of the first two studies to allow assessments of the gains acheivable incorporting the perfromance capabilites of actual wave prediction systems. In addition to the paper and simulation work typically affordable in faesibility studies the key novel scientific elements (mainly the prediction aspects) will but the subject of actual field studies. This is possible by virtue of the proposed project falling under the umbrella of the new Penninsular Research Institute for Marine and Renewable Energy (PRIMARE) which is linked to the commercial South West Wave Hub. The project will have access to the PRIMARE wave and current sensor grid which is an intensively instrumented 3km by 4km area of sea 20km off North Cornwal corresponding to the site for a group of commercial wave energy converters.
