가스 터빈의 클리어런스 제어 시스템에서, 제어 장치는, 부하의 변동 폭이 미리 설정된 범위 내에서 추이하는 부하 안정 상태가 된 경우에, 제 1 유량이 제 2 유량보다 커지도록 조절 장치를 작동시키고, 부하가 범위 외가 되는 부하 변동 상태가 된 경우에, 제 2 유량이 제 1 유량보다 커지도록 조절 장치를 작동시킨다. In a clearance control system for a gas turbine, a control device operates an adjustment device such that a first flow rate is greater than a second flow rate when a load stable state is entered in which a fluctuation range of a load shifts within a preset range, and operates the adjustment device such that the second flow rate is greater than the first flow rate when a load fluctuation state is entered in which the load falls outside the range.
