Abstract
Solar concentrators solve energy problems within a short time. The central tower technology stands out due to the ability to concentrate many solar rays. These plants have fields of heliostats that reflect the radiation to a receiver. Heliostats make up the bulk of the investment in this system, improving field efficiency promotes cost savings. The purpose of this work is to analyze how some parameters can influence the performance of a solar field located in the city of Natal - RN. Simulations were performed in the Scilab software using a model that calculates the performance of the system due to the movement of the Sun and the various mechanisms of losses. An analysis of the characteristics of the field is made, such as the height of the tower and the distance between the tower and the heliostats, for two types of distribution of the heliostats. For the distribution Model II, an efficiency of approximately 54% and a reflected potency of 95,915 kW was obtained. For Model I, 50% and a production of 92,304 kW were obtained. It can be concluded that with a larger tower height and a smaller tower-heliostat distance the system can achieve better efficiency values.
