摘要

在利比亚南部，有许多发电厂和其他大型工业开发项目使用其电力系统，如油田。由于该地区缺水，经常使用燃气轮机，例如阿斯里尔油田发电厂。然而，燃料运输‎一‎成本和安全方面的主要困难之一。燃料运营和‎运输‎被认为很高；因此，这项工作‎旨在利用‎太阳能有潜力降低燃料消耗。在这种情况下，目前正在利比亚运营的一家发电厂‎位于西南部撒哈拉沙漠附近的一个村庄被选为案例研究。这个‎之所以选择这个地区，是因为它为建立集中的发电厂提供了特殊的条件。模拟研究是在满负荷下进行的，考虑到太阳通量的性质随‎气象条件和热力学计算是基于描述动力循环和‎太阳能场。此外，使用‎还分析了CSP系统‎. 太阳场的年度行为是使用系统顾问模型（SAM）软件中的每小时数据确定的。为了检验燃料减少的可能性，从经济角度将燃料成本与火用分析联系起来。这个‎发现‎植物‎可以通过预热进入燃烧室的空气温度来提高效率并且降低燃料质量比。‎ 燃烧器的空燃比为43，输送到燃烧室所需的设计热能为414.4MW，动力循环的能量热效率为32.6%。当平均直接辐射等于1000kWh/m²时，太阳能场的热功率设计为532MW。

The Potential of Using the Incorporation of Concentrated Solar Power and Gas Turbines in the South of Libya

In the southern part of Libya, there are a number of power plants and other large industrial developments using their power systems, such as petroleum fields. Gas turbines are frequently employed due to water scarcity in the region, such as the Asrir field power plant. However, fuel transportation is ‎one ‎of the main difficulties regarding cost and safety. The annual cost of fuel operation and ‎transportation ‎is admitted to be very high; therefore, this work ‎aims to utilize ‎solar energy potential to reduce fuel consumption. In this context, a power plant that is currently in operation in Libya, which is ‎located close to the Sahara Desert in the southwestern region, was selected as a case study. The ‎region was chosen because it offers extraordinary conditions for the establishment of concentrated power plants. Simulations studies were carried out at full load considering the nature of the solar flux that varies with the ‎meteorological conditions and the thermodynamic calculations were made based on algebraic equations describing the power cycle and the ‎solar field. In addition, the feasibility of fulfilling the power cycle's energy required using the ‎CSPs system was also analyzed‎. The annual behavior of the solar field was determined using hourly data within the system advisor model (SAM) software. In order to examine the possibility of fuel reduction, the cost of fuel was linked with an exergy analysis from an economic perspective. The ‎findings revelated ‎that the plant ‎efficiency could be increased and the fuel mass rate ratio could be reduced by preheating the air temperature entering the combustion chamber.‎ The air/fuel ratio at the combustor was found 43, the design heat energy required to deliver to the combustion chamber is 414.4MW, and the energetic thermal efficiency of the power cycle is 32.6%. The thermal power design of the solar field is 532MW when average direct irradiation is equal to 1000kWh/m².
