我们使用1958 - 2011年的NORA 10后报数据，研究了东北大西洋和北海地区三浮子M4波浪能转换器产生的功率的变化。其目的是调查所产生的电力是否也受到冬季气候变化（如北大西洋振荡）的强烈影响，就像以前的研究中观察到的海浪电力资源一样。在这项研究中，我们展示了使用代用指数与气候指数相结合，以重建1665 - 2005年的历史实际波能气候。我们还进行敏感性研究，以评估实际波功率的变化，响应扰动的机器尺寸，功率起飞系数，响应带宽和功率限制的功率起飞。我们发现，由此产生的时间变化仍然是主导的气候变率。然而，由于M4机器的有限捕获带宽，对于电力可用性和能源供应经济性重要的整体可变性小于海洋波浪电力资源的整体可变性。这里提出的统计方法也可能与类似地点的其他波浪能转换器相关。
We look at the variability of the power produced by the three-float M4 wave energy converter for locations in the North-East Atlantic and North Sea using the NORA10 hindcast data from 1958−2011. The aim is to investigate whether the produced power is also strongly affected by the climate variability (such as the North Atlantic Oscillations) in the winter, just as the ocean wave power resource as observed in previous studies. In this study, we demonstrate the use of proxy indices in combination with the climate indices to reconstruct a historic practical wave power climate from 1665−2005. We also conduct sensitivity studies to assess the changes in the practical wave power variability in response to perturbing the machine size, the power take-off coefficient, the response bandwidth and the power limit of the power take off. We find that the resultant temporal variation is still dominated by the climate variability. However, the overall variability important for power availability and energy supply economics is smaller than that of the ocean wave power resource because of the finite capture bandwidth of the M4 machine. The statistical methodology presented here is also potentially relevant to other wave energy converters in similar locations.
