Abstract

In order to provide a method of operating a solar thermal power plant, in which a heat transfer medium is evaporated endothermally by solar radiation in an evaporator section, wherein the evaporator section comprises a plurality of evaporator branches, among which the heat transfer medium is distributed, in which method non-uniform radiation conditions of the evaporator section may be effectively taken into consideration, it is provided that the mass flow distribution at the evaporator section is controlled, wherein the mass flows are adjusted individually at all or a majority of the evaporator branches and a controlled variable is a variable characterizing a spatial energy rise in a respective evaporator branch in a region of the evaporator branch where the heat transfer medium has not yet evaporated.
