Abstract
More recent development in smart grid technology and communication system, power protection of transmission system leads to next level of digitization. The proposed technique shows the feature with digital protection of system integration protection scheme (SPIS) for large power transmission grids to address faults based on phasor measurement units. The fundamental assumption of the protection scheme depends on comparing positive sequence voltage magnitudes at each bus during fault conditions inside a local backup protection centre to locate the nearest bus to the fault. Then the absolute differences of positive sequence current angles are compared for all lines connecting to this bus to detect the faulted line. This new technique depends on synchronized phasor measuring technology with high speed communication system synchronized with GPS clock pulse. The simulation of the interconnecting system is applied on 220 kV Odisha Power Transmission Corporation (OPTCL) network using Matlab Simulink. The new technique can successfully distinguish the faults for interconnected lines. The new protection scheme works as unit protection system for long transmission lines.
