SENSITIVITY ANALYSIS OF FAULT LOCATORS IN POWER DISTRIBUTION SYSTEMS CONSIDERING DISTRIBUTED GENERATION

This paper presents the methodology to perform sensitivity analysis for impedance-based fault location methods, considering power distribution systems and the presence of distributed generation. The proposed methodology helps to determine the power distribution system model parameters, which significantly affect the fault locator performance. Having identified such parameters, the next step is to perform analysis and compensations aimed to develop more robust locators. As result of the proposed methodology, a set of critical parameters of the power system model is here identified.
