RTDS - A Fully Digital Power System Simulator Operating in Real Time

Abstract

Abstruct - This paper presents details on the design, architectural features and applications of a real-time digital simulator (RTDSm) developed at the Manitoba HVDC Research Centre (Winnipeg, Canada). Custom hardware and software have been developed and collectively applied to the simulation and study of electromagnetic transients phenomenon in power systems in real-time. The combination of real-time operation, flexible YO, graphical user interface and an extensive library of accurate power system component models make the RTDS an ideal simulation tool with a wide range of applications. I. INTRODUCTION Simulation has long been recognized as an important and necessary step in the development, design and testing of power generation and transmission systems. A wide variety of both analogue and digital simulation tools are available and typically used during various stages of system development. Recent advances in both computing hardware and sophisticated power system component modelling techniques have significantly increased the application of digital simulation in the power system industry. Of particular interest in the context of this paper are the advances made in the study of electromagnetic transients phenomenon.
