Real time power system simulators are widely used in the electric power industry by utilities, equipment manufacturers and research organizations. The simulators are used to study the power systems themselves as well as for the development and testing of new equipment to be installed in power systems. In particular, electric power utilities have used these systems for closed-loop testing and training on control and protection for HVDC, FACTS, generators, transmission lines, transformers, etc. These simulators provide continuous, hard real time, ElectroMagnetic Transient (EMT) simulation results. EMT simulation is necessary to provide the instantaneous value results needed to test real protection and control equipment. Over the years, the hardware and software of these simulators has undergone many improvements since they were first being introduced commercially in the early 1990’s. The improvements have increased their performance and widened their scope of application. The paper focuses on the
applications of real time digital simulators at electrical utilities.
