Abstract The operational performance of conventional overcurrent protection relay coordination connected to a distribution network is adversely affected by the penetration of distributed generators (DG) at different buses in the network. To address t

The conventional distance protection scheme is usually affected by uncertainties associated with transmission line parameters and some uncontrolled parameters like fault resistances. By varying the fault resistances, errors are introduced in the faul

FACTS devices are presently used to improve the power transfer capability of a transmission line and voltage stability of a power system network. Shunt injected current (Ish) by the Static Var Compensators (SVC) causes underreach or overreach of dist

The availability of zero-sequence current, under normal circumstances, determines the accuracy of the operation of a distance relay which is connected to a mutually coupled parallel line. When this is not available, the system adopts a different comp

The proper understanding of the nature and sources of low-frequency oscillations presents a problem for power systems in developing countries because of the inherent continuous network expansion and overloading. In this paper, a thorough study of osc

The power systems in developing countries are usually stressed and operated near their stability limits. Consequently, accurate sources of oscillations and their controls can present a challenge. This paper reports a comprehensive study of the oscill

The variation of fault resistances introduces error in the measured apparent impedance of the conventional distance protection scheme. With this, the measured apparent impedance at the relay location is not proportional to its length. This paper pres
