Abstract

The simultaneous ac-dc power transmission system can improve the transient stability of a power system. A mathematical model for ac-dc composite system, suitable for stability analysis, is developed in this paper. To compare the ac transmission system with the composite system a comprehensive analysis in terms of stability is made using the proposed model. A numerical analysis is also carried out to compare the stability of the composite system with that of a system with ac transmission only.
