Objective Compressors and turbines are two key equipment in compressed air energy storage power stations, and their control is usually achieved by the equipment's built-in control system, resulting in scattered control and a complex regulation process. With the proposal of DCS (Distributed Control System) integration technology, it is significant to carry out DCS integration technology for compressed air energy storage power stations.

Method Firstly, the current research status of compressed air energy storage power stations was analyzed from the perspectives of DCS, compressor control systems, and air turbine control systems. Then, three DCS integration approaches were proposed, and the feasibility and advantages of implementing DCS integration in such power stations were analyzed. Finally, the DCS integrated configuration scheme was explored.

Result Through the analysis of compressed air energy storage power stations, the difficulty in achieving integration lies in the control systems of compressors and air turbines. The results show that the integration of DCS for the two major equipment is technically feasible.

Conclusion This paper introduces the integrated DCS design analysis for the entire compressed air energy storage power plant, providing ideas and directions for subsequent design of DCS integration solutions for such power stations, as well as a method for achieving their centralized control.
