Global Positioning System Application in Current Phase Comparison of Differential Protection Relay of Power Transmission Line

Development of a New Bus Zone Identification Algorithm Based on Phase Angle Comparison Using Sequence Components of Currents

“…The performance of the proposed algorithm has been tested and verified over a large test data set considering wide variation in different system and fault conditions. The work presented in this article can be useful for the further enhancement of research in the area of fault analysis, busbar protection, fault locating algorithm, and protection of parallel lines [15][16][17][18][19]. In this article, Section 2 describes the concept of the proposed scheme.…”

“…In [17], a microprocessor-based relay has been developed using waveform comparison technique. References [18,19] present phase angle comparison based global positioning system (GPS) and phasor measurements units (PMUs) technique for the protection of transmission line. The above mentioned three fault locator/detector methods are more accurate than the method based on unsynchronized phasors.…”
