项目摘要

Ocean wave energy can be harnessed by a group of wave energy converters deployed together to generate electricity from the kinetic energy of ocean waves. Such wave energy arrays are often located near the coast or offshore, consisting of multiple devices, such as floating buoys, and connected to the grid through power transmission. In the present work, the multiple scattering theory is employed to assess the array performance in multi-directional irregular waves. Based on the meteorological occurrence probability of each sea state and the power matrix of each converter, the annual power production at a localised site is evaluated quantitively. Moreover, the developed numerical method is used to select the most appropriate site for given arrays considering the varying sea states in a year.

海浪能可以通过一组波浪能转换器利用海浪的动能发电。这种波能阵列通常位于海岸或近海附近，由多个装置组成，如浮动浮标，并通过电力传输与电网相连。本文将多重散射理论应用于阵列在多向不规则波中的性能评估。根据各海况的气象发生概率和各变流器的功率矩阵，定量评价局地站点的年发电量。此外，利用所开发的数值方法，考虑一年内海况的变化，为给定阵列选择最合适的位置。
