Solar heat turbine system, and device and method for controlling said system

摘要

In the present invention, for example, when a stop request has occurred in a solar heat turbine system, a restriction mechanism is caused to restrict the flow of at least one of a high-pressure working fluid and a high-temperature working fluid, so the energy of at least one of the high-pressure working fluid and the high-temperature working fluid can be restricted, said fluid being used to operate the solar heat turbine system. At this time, because bleeding is not executed instantaneously, an increase in the rotation speed of a compressor can be suppressed as the fluid serves as a load, thereby successfully preventing over-speeding of the solar heat turbine system. In addition, because a high-pressure working fluid that is in the process of being generated by the compressor is bled as a bled working fluid after at least one of the high-pressure working fluid and the high-temperature working fluid is restricted, the internal pressure of the compressor, over-speeding of which is prevented, can be reduced, thereby successfully preventing surging of the compressor.
