Abstract

The addition of dynamic models of loads, machines and subtransmission networks to the existing three-phase real-time simulator of Hydro-Quebec (IREQ), has made available a tool appropriate for the study of power system dynamics in real time. The valid frequency range of the simulator, which already covered harmonics up to 2000 Hz, has been extended to include machine dynamics in the region of less than 1 Hz. The paper describes the models added and also presents some results of the integration of these dynamic models, showing how they compare favorably with equivalent results obtained using a transient stability simulation program
