Differential Relay modelling using MATLAB Simulation procedure

Simulink : Simulink is a block diagram environment for multidomain simulation and Model-Based Design . It supports simulation, automatic code generation, and continuous test and verification of embedded systems. Simulink provides a graphical editor, customizable block libraries, and solvers for modeling and simulating dynamic systems. It is integrated with MATLAB ® , enabling you to incorporate MATLAB algorithms into models and export simulation results to MATLAB for further analysis Differential Relay Principle of Differential Protection scheme is one simple conceptual technique. The differential relay actually compares between primary current and secondary current of power transformer , if any unbalance found in between primary and secondary currents the relay will actuate and inter trip both the primary and secondary circuit breaker of the transformer. Suppose you have one transformer which has primary rated current I p and seconda...

Differential Relay Advantage and Disadvantage

Differential Relay: Principle of Differential Protection scheme is one simple conceptual technique. The differential relay actually compares between primary current and secondary current of power transformer , if any unbalance found in between primary and secondary currents the relay will actuate and inter trip both the primary and secondary circuit breaker of the transformer. Differential Relay Scheme What is the advantages and disadvantages of a differential relay. Advantage:  Fully digital signal handling with a powerful 16-microprocessor and high measuring accuracy on all the setting ranges due to an accurate 16-bit A/D conversion technique.  Easily adaptable to various substation and alarm system with flexible signal grouping marix in the relay. Disadvantage:  There may be a probability of mismatching in cable impedance from CT secondary to the remote relay panel.  These pilot cables capacitance causes incorrect operation of the rel...

Power System Protection for Power plant , Generation station , Transmition lines

Power system protection needs for all sector for control the whole system. Protection Units: Block Diagram for Protection System When a faulty occurs in the power system The Fault is sensed by a CT(Current Transformer) then, CT sends a signal to a protective Relay and Protective Relay gives a tripping command to CB(Circuit Breaker) Fault is cleared by isolating the faulty part of the network as quickly as possible.
