      Wind power generation occupies a vast land area. Currently, collection lines in wind farms mostly consist of overhead, cable, T-junction branch, or mixed configurations. These collection lines are long and have complex structures, making it difficult to identify hazards and faults. Patrol tasks for fault detection are labor-intensive and lack advanced intelligent technology assistance, resulting in low inspection efficiency. The monitoring device for wind farm collection/transmission lines detects transient and steady-state fault signals occurring on these lines and uploads them to the data center for analysis and diagnosis. This enables rapid localization of hazards and faults, facilitating real-time online monitoring of wind farm line operations.
