Three Zone Detection and Distance Relay Co-ordination of an IEEE Nine Bus System

Sri Ram C


To protect the transmission lines against faults, distance relays are mostly used. Distance relay has its own Resistance(R) – Reactance(X) characteristics. Co-ordination of different distance relays is necessary for the fast operation of circuit breaker. Multiple relays with circuit breakers are connected at different buses far from each other and the tripping of these relays are observed with respect to the distance of fault occurrence from the bus. Relay characteristics are shown with zone detection before and after fault occurrence. In this paper, co-ordination of impedance (Z) relay is set with faults are placed at different locations of IEEE 9 Bus system. A comparative analysis is bringing off with severe fault at different locations on IEEE 9 bus systems in MATLAB Simulink GUI environment generating graphs plotted with respect to time.
