Abstract
The favorable heat transfer characteristics of sodium makesit possible to collect concentrated solar radiation at medium high temperatures in small active areas, and therefore, with relatively low losses. However, because of the intermittent nature of the solar source, the receiver and the sodium pump controls must be designed and operated so as to obtain adequate responses to insure receiver structural integrity. The two receivers installed and tested at the site represent two different coolant flow approaches, each of which pose different demands on the control system. This evaluation area reports on studies of this problem situation and in the final analysis, attempts to make clear the necessitity of system integration; that is, the need to design a coolant flow control system specifically for a receiver. This was not the completly true case at SSPS for either receiver. Even with the cavity installation the control was designed for an input power level much higher than was finally realized. The ASR, of course, was required to accommodate the coolant flow/pum** situation that was installed with minimum modification.
The work here described was carried out at ENEL — Automation and Computing Research Center, Cologno Monzese (Milan), Italy by S. Quatela and G. A. Magnani.
SdI designed the ASR direct digital controller.
