Utility applications of a RTDS® Simulator

The RTDS Simulator is a fully digital, real time power system simulator widely used in the industry. The system provides continuous real time electromagnetic transient simulations based on the Dommel algorithm. The simulator hardware and software have both undergone many improvements since the simulator was first introduced in the early 1990's. The improvements have increased the performance of the simulator and widened its scope of application. In particular, electric power utilities have used the system for closed-loop testing and training on controllers for HVDC, SVC and generators, closed-loop protective relay testing, and large scale real time simulation. The paper describes the simulator design and its utility applications in greater detail.
