Introduction  According to the actual operation of offshore wind farms, this paper has been integrate the monitoring systems of offshore wind, offshore substation, and onshore centralized control center. This paper proposes the smart offshore wind farm integration monitoring system.

  Method  This article analyzed the system architecture, functional requirements, data processing, and security partitioning. In this way, the operation mode in which the offshore substation for a wind farm offshore wind farm was unattended and a land-based centralized control center was operated by few people can be achieved. The system showed that the several subsystems such as wind monitoring, offshore substation monitoring, video and environmental monitoring, wind power forecasting, cable fault monitoring, and equipment condition monitoring systems had been effectively integrated.

  Result  It can provide complete monitoring functions for major electrical equipment, which can realize operational monitoring, operation and control, comprehensive information analysis and intelligent alarms, operation management, and assistance for these five applications.

  Conclusion  Therefore, it can reduce the operating costs of wind farms and achieve the goals of advanced technology, complete function, reliable performance and economical rationality.
