Solar-thermal electric power generation using a system of distributed parabolic trough collectors
Abstract
The paper describes a solar-thermal collection and transport system for electric power generation. The system employs water as the working fluid; steam at 60 bars pressure and 276 C is generated locally by distributed parabolic solar collectors. A transfer loop conveys the steam to a central site at which the power plant is situated. The design of the collector and the operating characteristics of three transfer loop configurations are described. Results of experiments performed at a desert test site using a scale model of a solar collector module are presented. The data establish the efficiency of the collector both in the absence of heat losses and under normal operating conditions. The findings of life tests being performed on samples of candidate solar reflector surfaces are reported.
