As the need for analyzing complex power systems increases, simulation tools make possible adding coupling strategies to interface simulations with Real-Time (RT) and Hardware in the Loop (HiL) techniques. This paper introduces a novel hardware and software integration to reproduce a real-time performance environment of power system simulations, especially focused on protective relaying control adjustments and training tools. The IEEE-9 bus system and a real validated model of a Colombian transmission systems section are presented; both cases are implemented in the platform and reproduced with the aim of evaluating its performance. Finally, the different possibilities with the developed tool and future developments are presented.
