This work is part of the dynamic of proposing a solution to the problem of access to electricity in Chad, which has a rate of access to electricity of 3%. N’Djamena has significant solar potential that can be harnessed to generate electricity. In this paper, we present a theoretical study of the performances of the Dish/Stirling system with the purpose of producing electricity, based on a mathematical model taking into account each of the subparts of the system (concentrator, solar cavity receiver, and Stirling engine). Hydrogen is preferred to helium as the working fluid for operating the Stirling engine at high temperatures. This coupled model made it possible to estimate the monthly average of the electric power produced by this modular system and also its overall solar electricity yield.

碟式/斯特林系统发电的简化建模和仿真

这项工作是提出解决乍得电力供应问题的动力的一部分，该国的电力供应率为 3%。恩贾梅纳拥有巨大的太阳能潜力，可用于发电。在本文中，我们基于考虑到系统的每个子部分（聚光器、太阳能腔接收器和斯特林发动机）的数学模型，对以发电为目的的 Dish/Stirling 系统的性能进行了理论研究。 ）。作为在高温下操作斯特林发动机的工作流体，氢气优于氦气。这种耦合模型可以估计该模块化系统产生的每月平均电力以及其整体太阳能发电量。
