摘要：
This paper presents a fault detection and classification scheme, based on integrated impedance, for SVC compensated transmission line. For internal faults, integrated impedance of faulty phase is low and for healthy phase, it is high. For all external faults, integrated impedances of all phases are high. The protection scheme based on this concept is used for variable impedance shunt compensation (i.e. Static Var Compensator, SVC). Proposed scheme has been analyzed for each phase with different fault resistances, fault types and fault locations. The results demonstrate the effectiveness of the proposed scheme.
