Automatic Control System Software for the Gas Pumping Unit with an Anti-Surge Algorithm based on Trace Mode 6

Continuous gas transportation depends on the stable operation of GPU. However, this stability can be disrupted by a surge. Fighting this phenomenon is a complex technological task that requires a detailed study of the gas pumping unit's operation. Interaction of the operator with the ACS GPU is carried out through the adopted "man-machine interface", which regulates the order of the operations of preparation, start-up and control of GPU. Thus, implemented software based on TRACE MODE 6 with an anti-surge algorithm, previously the algorithm was implemented by a third-party device. The described ACS software implements the management of the technological process at all stages and already used on real gas pumping station (GPS).
