Abstract

The invention relates to a Steam Rankine cycle solar plant 10 and a method of operating thereof. The plant 10 comprises a steam generator 20 for generating steam from solar thermal energy, a feed line 32 connected to the steam generator 20 and a multi-stage turbine 30, with a first stage and an intermediate stage downstream of the first stage, connected to the steam generator 20 by the feed line 32. The plant 10 further includes an overload valve 45 located in the feed line 32. This overload valve 45 is configure and arranged to limit the steam pressure of the first stage by directing at least a portion of the steam into the intermediate stage above a predetermined steam turbine inlet pressure.

Description

technical field [0001] The present disclosure relates generally to steam Rankine cycle solar plants and, more particularly, to optimizing the performance of turbines within the steam cycle of such solar plants. Background technique [0002] In its most basic form, a solar thermal power plant consists of a solar concentrator with mirrors that concentrate solar radiation to one or more receivers where it is converted into high temperature heat energy. The general construction of a solar thermal power plant is based on a conventional Rankine-cycle power plant. In general, steam Rankine cycle based solar thermal applications typically fall into two general categories of capture technologies: linear focus technologies, such as parabolic troughs and linear Fresnel concentrators; and point focus concentrators, such as solar power tower. [0003] A parabolic trough is a type of concentrator built into a long parabolic mirror. At the focal point of the mirror is the Dewar through ...
