Electromagnetic electromechanical hybrid real-time digital simulator for the study and control of large power systems

The Polytechnic University of Hong Kong, in collaboration with the Hydro Quebec Research Institute has embarked on the development of a large bandwidth electromagnetic electromechanical hybrid simulator capable of modelling large scale power systems in real time or faster than real time, for studies ranging from electromagnetic transients to transient, dynamic, and voltage stability, with applications including closed-loop protection and control studies, as well as on-line dynamic security assessment. In this paper we review the development of real-time simulators and the broader applications of the next generation of simulators in the planning, design and operation of today's power systems.
