Resumen

PONCE, Carolina V  y  VALDERRAMA, José O. Influence of Solar Radiation on a Combined Cycle Plant with Integrated Solar Collectors by Simulation. Inf. tecnol. [online]. 2016, vol.27, n.3, pp.151-160. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642016000300014.

The effect of the variation of daily solar radiation on some variables of a thermoelectric power plant using a combined cycle with integrated solar collectors is analyzed. A combined cycle with integrated solar collectors plant (Integrated Solar Combined Cycle, ISCC) consists of three main components: i) the combined cycle power plant, ii) the field of distributed solar collectors and iii) a solar vapor generator. In this work, the combined cycle power plant and the distributed solar collector’s plant are integrated by adding a solar vapor generator to the solar plant that produces vapor for the ISCC plant. Material and energy balances are performed in the solar vapor generator and the computational implementation is done using Matlab-Simulink®. The pieces of equipment of both plants, the combined cycle power plant and the ISCC plant, are the same and the only change done is the source of energy that heats part of the vapor that goes to the super heater. The main variable of interest that is analyzed using the simulator is the flow of vapor that is produced in the solar vapor generator and that contributes with a maximum of 10% of the total vapor consumed during the peak hours of solar radiation (11 am to 15 pm). The simulator developed in this work represents a good tool to study the effects of variation of daily solar radiation in a combined-solar plant.

Palabras clave : combined cycle; integrated solar collectors; process simulation; solar energy.
