Zusammenfassung:	Provided are an apparatus for preventing a surge of a centrifugal compressor reducing the possibility of surge occurring in a centrifugal compressor and a method therefor. The provided apparatus comprises: a control unit controlling gas providing operation based on a flow rate of an input side of the compressor and pressure of an output side of the compressor; and a gas providing unit storing a portion of a gas introduced to the input side of the compressor and providing the stored gas to the input side based on a control signal of the control unit. 원심압축기에서 서지가 발생할 가능성을 줄이기 위한 원심압축기의 서지 방지 장치 및 방법을 제시한다. 제시된 장치는 압축기의 입력측의 유량과 압력 및 압축기의 출력측의 압력을 근거로 가스 제공 동작을 제어하는 제어부, 및 압축기의 입력측으로 유입되는 가스의 일부를 저장하고 저장된 가스를 제어부의 제어신호에 근거하여 입력측으로 제공하는 가스 제공부를 포함한다.
