Abstract
The graphical method for a no-blocking radial staggered layout was
introduced within the joint work between the Center For Solar Energy
Studies (CSES), Tripoli, and Atlantis Energy Ltd, Bern. It locates
the heliostats in the field of a solar central receiver plant so
that they provide no blocking losses over the year. In this method
the field is divided into certain groups to increase the efficient
use of land. The method is a simple one when compared to cell-wise
procedures, making it more suitable for preliminary design of heliostat
fields. At the same time, the method can be represented by a set
of mathematical equations, consequently facilitating its computer
implementation. In this paper a mathematical formulation of the method
will be introduced, as well as its algorithm. Also, a criterion for
the transfer to a new heliostat group is proposed based on mirror
density.
