Cooperative multi-agent-based control technology for supervisory control and data-acquisition systems

Through the research reported here, a SCADA system with improved serviceability has been developed. Introducing the multi-agent (MA) technology into a distributed control system can reduce system and improved serviceability. To further improve serviceability and make the system more cost-effective, the predictive-agent function and inter-terminal parameter method were also applied. In addition, the system´s distributed intelligent field terminals (IFTs) use a common algorithm that is unaffected by any changes to the system specifications. As a result of these innovations, the serviceability of the proposed system is significantly improved compared to that of conventional systems. This system has been implemented for practical purposes at 29 sites.
