本文基于英国拟议的 8 吉瓦塞文拦河坝方案的运行模式建模，首次提出了潮汐拦河坝发电的详细容量值计算。主要发现是，有效承载能力占装机容量的百分比非常低（此处提供的示例小于 10%）。这是因为，如果峰值需求发生在潮汐周期的错误部分，则峰值需求时的可用输出很可能为零；这个结果可以使用简单的拦河坝两种状态模型来透明地解释。还讨论了建立潮汐拦河坝可用性概率模型的前景。
This paper presents the first detailed capacity value calculation for tidal barrage generation, based on modeling of operational modes for the proposed 8-GW Severn Barrage scheme in Great Britain. The key finding is that the effective load carrying capability is very low as a percentage of installed capacity (less than 10% for the example presented here). This is because of the high probability of having zero available output at time of peak demand, if peak demand occurs on the wrong part of the tidal cycle; this result may be explained transparently using a simple two-state model of the barrage. The prospects for building a probabilistic model of tidal barrage availability are also discussed.
