Fault Section Identification System for 35kV Transmission Lines Based on Correlation of Fault Current Waveforms
In response to the complex topology of 35 kV transmission lines and the inability to reliably apply traditional fault section identification techniques,the transient current characteristics of ground faults in 35 kV multi branch hybrid transmission lines and the correlation of transient current waveforms at fault times were studied,and criteria for section identification were proposed.By developing correlation based on transient current waveforms,the online monitoring equipment for identifying 35 kV multi branch fault sections and the main station system for section identification can effectively solve the problem of identifying fault sections in 35 kV multi branch overhead cable hybrid lines.The system has certain engineering practical value,economic and social benefits.
