Wind power generation covers a wide area, and currently, the collection lines of wind farms are mostly overhead, cables, T-branch lines, and mixed frame lines. The collection line is long and the line structure is relatively complex, making it difficult to identify hidden dangers and faults. The task of fault line inspection is heavy and there is no advanced intelligent technology to assist in the formulation of collection line fault inspection strategies, improving the efficiency of fault inspection. The wind farm collection/transmission line monitoring device monitors the transient and steady-state fault signals at the time of collection/transmission line faults, and uploads them to the data center for analysis and diagnosis, achieving hidden danger warning and rapid fault locations of collection/transmission lines, and real-time online monitoring of the operation status of wind farm lines.
