FluxSPT: Tool for Heliostat Field Aiming and Flux Mapping in Solar Power Tower Plants

FluxSPT is a software tool for the characterization of heliostat fields. A GUI-based version of this tool is available for free download, which requires the installation of Matlab Runtime, freely available too. FluxSPT generates the flux maps on central receivers from a heliostat field, considering its optical losses. The optical model is based on the convolution-projection method, previously validated by the authors. Symmetric flux distributions respect to the receiver midplane are computed using either the single or the multi-aiming strategy. For the multiaiming strategy, a single parameter (k aiming factor) is utilized to spread aimpoints and control the allowed peak flux and spillage.
