Fault Detection in Distribution Network with the Cauchy-M Estimate—RVFLN Method

Fault detection is an important issue in today’s distribution networks, the structure of which becoming more complex. In this article, a data-based Cauchy weighting M-estimate RVFLNs method proposed for short-circuit fault networks. The detects short circuits based on current and voltage measurements. addition, noises were added to data ensure robustness method. performance was examined RTDS RTS simulator using IEEE 33-bus-bar system model with help real-time simulations. success rate between 98% 100% low-impedance (0 ohm) faults, depending type. high-impedance (100 are difficult detect, 80% 92%,
