Fault Location Estimation in Power Distribution Systems with High Penetration of Distributed Generation

S. B. Karajgi Udaykumar and R. Y. G. D. Kamalapurs

Abstract—This paper analyses the effect of penetration of Distributed Generation on the estimation of Fault location in the power distribution systems. A single line to ground fault is considered on a real power distribution system and the estimation of the fault location is carried out using the impedance method which requires the measurement of voltages and currents at one measurement point and the heavy penetration of distributed generation alters these values causing errors in the estimated location. Simulation tests have been carried out for different DG outputs with varying fault impedances. The errors have been found to be more pronounced with larger penetration of DG and with lower values of Fault impedance.

Index Terms—Fault impedance, distributed generation, fault location.
