Abstract: Fault Simulations are very important to study the nature of the systems in place and thus test the Protective Relays under those conditions. Omicron modules have very high accuracy in its class of Power System simulators, not only in the steady regions but the transient states as well. This paper focuses on the Fault Simulation on a Distribution Network through MATLAB and the Omicron module. The faults are simulated on a distribution model (using the Sim Power Systems® Tool) in MATLAB. MATLAB is interfaced with the Omicron module (using CM Engine®) for the real time testing of the relays. The GUI gives added functionality and ease of use to the user. A report generator is added, which generates a report of the simulation along with the waveforms.

Keywords: Fault Simulations, GUI, Omicron Power System Simulator, Protective Relays.
