The sub-control systems in the architecture of conventional compressor station control system have various types and complex architecture, leading to excessive failure points, large maintenance amount, frequent data communication, etc. Taking Gaizhou Compressor Station as a pilot, the method integrating the compressor station control system with the compressor unit control system was proposed. The compressor unit load control system was integrated into the station control system. After SIL certification, the compressor unit process control system and safety instrument system were combined, thus reducing the number of control systems. Both the HMI of the compressor unit control system and the HMI of the unit load distribution control system were integrated into the HMI of the station control system, so that the display of all controlled equipment and parameters in the compressor station could be controlled by the HMI interface of station control system. Upon the completion of the system integration, the station control system network was divided into control network and equipment network, separated from each other, and could effectively ensure the safety of the unit control system. The results of the pilot application show that during the construction period, the hardware investment is saved in the earlier stages. During the operation of the station, the number of failures caused by communication failure can be effectively reduced to better realize the one-key start and stop function of the station. The integration of compressor station control system and unit control system will not only reduce the number of control systems, improve the communication rate between systems, but also ensure the stable operation of each system.
