A Compressor Surge Control System: Combination Active Surge Control System and Surge Avoidance System
A novel method for combining active surge control system (ASCS) and surge avoidance system (SAS) for a centrifugal compressor is presented. ASCS is a promising method to improve compressor operating area by stabilizing surge. However, this method is not applied yet in industrial compressors. Safety issue is considered in implementing the ASCS. A failure in ASCS may endanger the compressor by en...
متن کاملIntroducing Back-up to Active Compressor Surge Control System
A novel method for introducing a back-up system to an active compressor surge control system is presented in this paper. Active surge control is a promising method for extending the compressor map towards and into the unstable area at low mass flow by stabilizing the surge phenomenon. The method also has potential for allowing operation at higher efficiencies. However, a failure in the active s...
متن کاملCentrifugal compressor surge and speed control
Previous work on stabilization of compressor surge is extended to include control of the angular velocity of the compressor. First a low-order centrifugal compressor model is presented where the states are mass flow, pressure rise, and rotational speed of the spool. Energy transfer considerations are used to develop a compressor characteristic. In order to stabilize equilibria to the left of th...
متن کاملActive surge control of compression system using drive torque
Novel control laws for a compression system using only the drive torque as control input are presented. Stabilization of any desired operating point is achieved with static or dynamic feedback. The stability results are derived using backstepping and passivity techniques. 2007 Published by Elsevier Ltd.
متن کاملRobust Control of Surge Instability in a Centrifugal Compressor
This paper proposes a robust design scheme for the control of surge phenomenon appearing in a centrifugal compressor. It is known the surge instability in compressor might lead to reduce the operating efficiency and even damage the machinery while both of unstable compressor characteristics and compressor load torque are hard to exactly measure in the practical application. Based on the assumpt...
