Abstract
Embodiments of the disclosure relate to systems and methods for determining a fault location in a three-phase series-compensated power transmission line system by using symmetrical components-based formulas that describe various voltage and current relationships. The voltage and current relationships can be derived using a synchronous measurement procedure that is concurrently executed at a sending end and a receiving end of the first series-compensated power transmission line system. Furthermore, determining the fault location in accordance with certain embodiments of the disclosure can eliminate one or more of a need to calculate an impedance value of any of the series capacitors or the series capacitor protection elements that are a part of the three-phase series-compensated power transmission line system, a need to monitor any of the series capacitor protection elements, and a need to measure a voltage drop across any of the series capacitors.
