Title:
並列運転される遠心コンプレッサ用安定性制御システム及び方法
Document Type and Number:
Japanese Patent JP2005534858
Kind Code:
A
Abstract:
A control system is provided to maintain stable operating conditions for centrifugal compressors operating in parallel when one of the centrifugal compressors enters into an unstable operating condition. The control system determines an unstable operating condition in response to signals indicating the motor current or power consumption of each compressor and the position of the pre-rotation vanes of the compressors. Once an unstable operating condition is determined, the control system closes the pre-rotation vanes to each compressor until the unstable operating condition has been corrected.
