AI Technical Summary

Technical Problem

Existing remote restart methods have complex system architectures, high overall hardware costs, and suffer from insufficient security and low levels of intelligence, making it difficult to meet the needs of offshore wind power for high availability and intelligent operation and maintenance.

Method used

By utilizing the remote communication lines and system anomaly signals of the offshore wind power equipment, the power supply lines of the control and protection devices can be disconnected and reconnected through the controller, eliminating the need for I/O modules and dedicated communication cables. Combined with the sysFail signal for deep coupling, fault-driven unattended self-healing operation can be achieved.

Benefits of technology

It reduces hardware costs and space requirements, improves the level of automated management, enables unattended self-healing operation, supports flexible deployment with on-demand activation, avoids accidental triggering, and improves the security and intelligence of the system.
