留尼汪岛严重依赖化石燃料，但寻求到2025年实现能源自给自足。海洋热能转换提供了一种发电手段，通过利用海洋深层和上层之间的温度梯度来利用海洋的可用能量。本文介绍了计划安装在留尼汪岛圣皮埃尔大学的实验设施。通过使用等效Gibbs系统的概念，(在Delphi界面上)建立了安装的动态模型。在这样的等效系统中，质量、能量和熵通过吉布斯方程联系在一起，而熵的产生可以很容易地用通量及其关联力来表示。假设线性现象学定律，现象学系数从技术数据中估计。使用数字工具(Genopt)进行了优化研究，以便根据海水温度确定最佳运行参数。这个模型让我们能够预测留尼汪岛上这项技术的潜力。一旦在该设施上得到验证，该模型将作为一种工具，帮助设计计划于2014年建造的未来10 兆瓦试点电厂。版权所有©2012 John Wiley&Sons，Ltd.
Reunion Island is heavily dependent on fossil fuels, but seeks to become energy self‐sufficient by 2025. ocean thermal energy conversion provides a means of producing electricity that harnesses the available energy of the ocean by using the temperature gradient between its deep and its upper layers. This paper presents the projected experimental facility which is to be installed at the University of St. Pierre on Reunion Island. A dynamic model of the installation has been developed (on a Delphi interface) by using the concept of equivalent Gibbs systems. In such equivalent system, mass, energy, and entropy are linked through the Gibbs equation, and the entropy production can easily be expressed in terms of fluxes and their related forces. Assuming linear phenomenological laws, the phenomenological coefficients are assessed from technical data. Using a digital tool (Genopt), an optimization study has been conducted in order to determine the best operating parameters according to the temperature of the sea water. This model allows us to anticipate the potential of this technology on Reunion Island. Once validated on the facility, the model will serve as a tool to assist design of the future 10 MW pilot plant planned for 2014. Copyright © 2012 John Wiley & Sons, Ltd.
