Abstract
Solar power plants of the SEGS-type gained enormous attention within the last years. A number of plants are already under construction or even close to grid operation. The bases for these developments are the experiences gained with the American plants in the past 20 years. This paper concentrates on two aspects concerning the operation of the plant which are, according to the authors experience, often not considered in the design phase of a new plant although their impact on the performance or component requirements of the plant is quite significant. The aspect of defocusing at over-load is analyzed by energy balances. The second field of oil temperature controllability is studied using a dynamic simulation tool.
