A VERSATILE FACTS DEVICE MODEL FOR POWERFLOW AND STABILITY SIMULATIONS

While early PACTS devices consisted mainly of thyristor-controlled/swi tched RLC/transformer components, the newer generation is based on the self-commutated voltage-sourced converter. The variety of devices and applications, and the changing nature of the technology, Fall for ver satile modelling capabilities at different levels of detail. This pape r describes a model conceived as a coordinated and interconnected set of controllable shunt and series elements. For each device, functional characteristics, typical settings and controls, and simulation exampl es are presented. The model is capable of representing virtually any P ACTS device for powerflow and all types of stability simulations.
