Distributed generation (DG) is gaining popularity in the United States and across the world. The Florida Public Service Commission recently passed rules encouraging the use of renewable resources. Integrating DG with the utility network poses challenges for anti-islanding schemes. These schemes detect islanding conditions and trip the DG. Fig. 1 shows a typical network configuration for DG installations...
This paper presents a new transient based scheme to detect single phase to ground faults (or grounded faults in general) in distribution systems with high penetration of distributed generation. This algorithm combines the fault direction based approach and the distance estimation based approach in order to determine the faulted section. The wavelet coefficients of the transient fault currents measured...
