Abstract
 This paper presents the simulation of digital overcurrent relay through the graphic interface SIMULINK which is one of the MATLAB toolboxes. The operating characteristics of SIEMENS inverse time overcurrent relay module was used as actual characteristics of the digital relay. The technique used is based on integrating the modeling of a loaded synchronous generator together with its digital overcurrent relay. The purpose of the paper is to provide a complete structure of the digital relay in order to check its performance. Various elements of the digital relay are implemented as single modules to represent the actual system. The computer digital relay module is tested under up normal conditions, and the results are very successful.
