OPAL-RT enables the simulation of large-scale, complex systems efficiently. Systems that would typically require hours or even days to simulate on a conventional personal computer can be executed in real time using OPAL-RT, with time steps in the microsecond or nanosecond range. High performance, flexibility, and low entry-level cost are key attributes of the OPAL-RT platform. The OPAL-RT real-time simulation platform is an advanced model-based engineering design and testing environment. It delivers outstanding real-time performance for experimental studies and is widely used in engineering design applications. Therefore, it is essential to examine its hardware architecture, software structure, and real-time performance in detail. A comprehensive understanding of its hardware and software architecture, along with its simulation process, provides a structured overview of the platform. Furthermore, the application of OPAL-RT in electrical power systems serves as a valuable reference for microgrid, smart grid, and other real-time system implementations.
