PROBLEM TO BE SOLVED: To improve turbine efficiency by reducing the temperature fluctuations of working fluid heated by a solar heat receiver. SOLUTION: Flow rate change quantity of working fluid to predetermined heat exchanger tube surface temperature or temperature of working fluid passing through an inside of the heat exchanger tube, and blade opening change quantity of a stationary blade or an inlet guide vane 2a of a compressor 2 to the flow rate change quantity of the working fluid are stored in a controller as database. In the controller, the highest data of temperature data sent from a piping temperature gauge or a fluid temperature gage is selected, flow rate change quantity of working fluid, corresponding to the temperature is determined; blade opening change quantity of the stationary blade or the inlet guide vane 2a corresponding to the flow rate change quantity is determined, and then the blade opening change quantity is converted to command signal and is output to a blade angle change mechanism changing opening of the stationary blade or the inlet guide vane 2a; and consequently, opening of the stationary blade or the inlet guide vane 2a is adjusted and flow rate of the working fluid flowing into the heat exchanger tube is adjusted.
