Design and Application of Control System in SQ Gas Storage

In recent years, China has introduced natural gas to foreign countries on a large scale. The construction of gas storage has been paid more and more attention by the national government because of its irreplaceable role and obvious advantages in peak regulation and gas supply security. This paper introduces the design content of SQ gas storage automatic control system from DCS (Distributed Control System), SIS (Safety Instrument System) and FGS (Fire and Gas System), so as to ensure the safe, reliable and smooth operation of SQ underground gas storage, and provide reference for the safety design of gas storage control system in the future.
