Monte-carlo study on a large-scale power system model in real-time using eMEGAsim

This paper describes a versatile, multi-domain, large power grid real-time digital simulator. Its ability to conduct multiple tests for protection coordination studies is described. A large grid model built using the EMTP-RV software and simulated in real-time using the eMEGAsim platform's EMTP-RT software tool is described. A discussion and comparisons on the different solvers offered with both simulation environments are made. Comparisons between off-line and Real-Time simulations are made using superimposed fault condition waveforms. Finally, multiple random tests are performed on the featured power system model and analyzed using the eMEGAsim simulator's software package.

1. Introduction

Simulators have been extensively used in the planning and design of transmission systems for decades. The state of the art has evolved from physical/analogue simulators (HVDC simulators, TNA's) for electromagnetic transients and protection and control studies, to hybrid TNA/Analogue/Digital simulators with the capability of studying electro-mechanical transient behavior [1], to fully digital real-time simulators.
