| Summary: | Modeling tools are useful for basic understanding of power system, particularly for new engineers. Such tools help the new engineers to modulate the system under normal and faulty conditions. This paper presents the modeling and simulation of digital reverse power relay on MATLAB/Simulink®. Various data conversion steps in digitization of a signal are also discussed. In the past, electromechanical relays were commonly used, now such relays have been replaced with high accuracy and high speed digital relays. Fast operation of relay is desirable, particularly for such type of faults which could lead to system blackout. Digital relays offer other advantages also, in term of multiple variable settings and compact size. In this paper, the relay performance is tested on 11kV synchronous generator, connected with 220kV through a step up transformer. |
