Abstract: The existing integrated automation system of onshore converter stations cannot meet the monitoring and management requirements of offshore converter stations in the future, so this paper puts forward the concept of intelligent construction of converter station. The paper first analyzes the operation and maintenance characteristics of offshore wind farm converter stations and current status of integrated automation system of converter stations. Based on requirement analysis of the field intelligent monitoring and remote intelligent operation, and maintenance and management of offshore converter station, through the application research of technologies such as comprehensive perception of equipment status, unmanned machine inspection, active warning of equipment abnormalities, intelligent diagnosis of equipment faults, intelligent linkage of main and auxiliary equipment, one-key sequential control of remote operation, intelligent control of personnel behavior, and intelligent decision-making of operation and maintenance management, this paper puts forward the design philosophy of intelligent monitoring and management integration system for converter stations in offshore wind farms, and studies and analyzes the architecture and functional characteristics of the system. It provides a feasible scheme for the intelligent and wisdom construction of the offshore converter station.
