The Application of Information Fusion Technique in the Early-Warning and Forecasting System for Switchbox Fault Arc

Aimed at the problem of poor accuracy and false positive rate in the early-warning and forecasting system for switchbox fault arc .low precision problem exited in fault location of transmission line, a new fault locating design is presented to improve the precision and speed of fault location. The short-circuit fault location in transmission line chooses DSP chip TMS320VC5507 as the central processing unit. This system can realize accurately in real-time acquisition and conversion of the fault traveling wave, and accomplish the fault location properly and removal immediately. The simulation results show that this system has the characteristics of quick detection and high precision.
