Combined transient and dynamic analysis of HVDC and FACTS systems

A new approach to HVDC and FACTS transient/dynamic simulation based on an interactive execution of an ac transient stability program (TSP) and the Electro-Magnetic Transients Program (EMTP) is described. Through the integration of the detailed transient model of FACTS with the transient stability program, authentic simulation is achieved without simplifications. Both HVDC and Thyristor Controlled Series Capacitor (TCSC) systems are used to validate the approach, under different coupling situations between both TSP arid EMTP.
