Solar-gas combined cycle system for generating electrical power

摘要

A system is provided for generating electrical power. The system comprises at least two turbine units among which a first turbine unit is configured to operate at a higher temperature than a second turbine unit and ingress means operative to enable introducing a working fluid being at an elevated temperature to the system. The system is characterized in that a) at least part of the incoming energy is received from a variable energy source and b) that it comprises: a controllable diversion means adapted to divert part of the working fluid before it arrives at the first turbine unit, and a controller operative to control the controllable fluid diversion means, and wherein the controller is operative to divert that part of the working fluid whenever thermal energy contained in the working fluid, exceeds a pre-defined threshold.
