A Review to Control and Monitor Solar Ponds

Abstract

Green collectors of electricity are salinity gradient solar ponds. By building a temperature gradient through the depth of the pond, energy is stored. All energy comes from an incident of solar radiation on the surface. The gradient of salinity, maintained and altered with depth, leads to temperature distinctions of up to 60 degrees. The heat produced could be used directly for a number of different purposes, or it can be converted into electricity that can be used in the plant or transported to the grid. The number of variables of the solar pond, i.e. the physical quantities, which are necessary for the proper functioning of this sort of power plant, is primarily controlled locally at the pond sites. Remote acquisition of data (DAQ) and, afterwards, regulation of the output of solar pond energy is more convenient and this is the focus of our study, as stated here. A solar pond control centre could be situated anywhere around the world with the use of wireless or wired networks, virtual private networks and the Internet, whereas the pond sites are chosen at the best solar opportunity locations.
