A unified model of a solar electric generation system (SEGS) is developed using a thermo-hydrodynamic model of a direct steam collector combined with a model of a traditional steam power house. The model is used to study the performance of different collector field and power house arrangements under Australian conditions. To find the effect of collector inclination on the SEGS overall performance, the SEGS performance is studied with a horizontal and an inclined DSG collector field by considering phase distribution and pressure drop in the collector field piping network. The appropriate spacing of collector arrays in the field is calculated by considering the shading between collectors. The annual performance of the SEGS is evaluated using the hourly radiation data for different sites in Australia.
