Wind Farm Collector Line Tripping Diagnosis Case
Wind-Induced Deflection Detected by SP3000 in Wind Farm
In 2024, collector lines at a wind farm in China frequently tripped, with the cause unclear. The project team invested about RMB 10 million in line improvements, upgrading tower hardware and replacing insulator strings, but the issue persisted. To resolve it, on December 8, 2024, five sets of SP3000 Fault Early Warning and Diagnosis System of Sunshine Power were installed on the collector lines.
On December 10-12, the system detected four trips, all at Tower 13. The O&M team inspected the area but failed to find the fault. After analyzing the fault data, the Sunshine Power’s technical team suggested that the tripping was likely caused by insufficient insulation distance between the ground wire and the transmission line due to wind-induced deflection.
After inspection, the fault location was identified, and the fault reason was confirmed. This case highlights the SP3000’s key role in fault detection and analysis, delivering significant economic benefits to the user.
