Abstract

Modern electric power systems are witnessing deployment of an increasing number of distributed renewable energy resources. Reliability of grid infrastructure plays a key role in increased use of renewable energies. Fault management is a key function in reducing outage time and increasing system reliability. In the past, various fault location methods have been proposed for electric power distribution systems. Most existing fault location methods are applicable to single faults and require a number of measurements. This paper proposes new algorithms for locating simultaneous, multiple faults for distribution systems using limited number of data. The method utilizes the voltage measurements taken from the systems. Bus impedance matrix techniques is harnessed to establish the connection between the fault locations of multiple faults and the measurements. The distinct features of the method include no need of fault type classification, consideration of shunt capacitance of long feeders, applicability to any type of faults, and suitability to systems with distributed generations. Evaluation studies have shown promising results. The methods can be integrated into existing distribution management system for enhanced fault management capability for power systems with distributed renewable energy sources.
