A real-time digital simulator (RTDS) is a high-performance computing system designed to model and simulate complex electrical power systems in real-time. It is mainly used to assess the behavior of electrical grids, components, and control systems under different conditions, without the risks or costs associated with physical experimentation. The primary goal of RTDS is to provide real-time analysis, validation, and optimization of system performance for research, development, and operational testing.

The key components of a real-time digital simulator include hardware, software, and services. Hardware refers to the physical components that support real-time modeling, processing, and interfacing with external systems. These include analog input and output boards, as well as digital input and output boards. RTDS is applied across various fields such as power systems, industrial automation, research and development, education, and training. Its main end-users include utilities, oil and gas companies, manufacturing, aerospace and defense, along with numerous other industries.
