A parametric analysis to identify the preferred plant components and configuration for a 100 MWe solar central receiver commercial power plant is described in detail. Components studied include heliostats, central receiver, storage system, electric power generation subsystem, and master control system. The advanced central receiver plant concept selected as a result of the parametric analysis is described. It consists of a 360/sup 0/ field of enclosed plastic heliostats focusing onto a cylindrical receiver operating at a peak sodium temperature of 1100 F. The heliostats are focused to slant range to achieve higher fluxes and lower receiver losses. Pressure reduction at the base of the downcomer is accomplished using a throttle valve complex. Hot and cold sodium is stored in separate arrays of field assembled tanks, and sodium is supplied to the steam generators by a pumping loop which is isolated from the absorber loop by the tanks. Separate steam generator modules provide the evaporation, superheat, and reheat functions required to deliver steam to a high efficiency steam cycle (2400 psi/1000 F/1000 F with heaters above the reheat point).
