提出了一种集成在联合循环电厂中的创新太阳能系统的性能评估，其中在线性抛物面集热器中流动的传热流体是引入电厂燃烧室的相同氧化剂空气。这一特性使工厂大为简化。在设计条件下，当电厂每天以标称体积流量工作时，化石燃料节省22%，每年节省15.5%，净平均年效率为60.9%，而没有太阳能集成的参考联合循环电厂的净平均年效率为51.4%。此外，该工厂进行了经济评估，这表明，太阳能部分的额外成本在大约5年内收回。
An evaluation of the performance of an innovative solar system integrated in a combined cycle plant is presented, in which the heat transfer fluid flowing in linear parabolic collectors is the same oxidant air that is introduced into the combustion chamber of the plant. This peculiarity allows a great simplification of the plant. There is a 22% saving of fossil fuel results in design conditions and 15.5% on an annual basis, when the plant works at nominal volumetric flow rate in the daily hours.The net average year efficiency is 60.9% against the value of 51.4% of a reference combined cycle plant without solar integration. Moreover, an economic evaluation of the plant is carried out, which shows that the extra-cost of the solar part is recovered in about 5 years.
