Abstract:In this paper the fundamental frequency electromagnetic induction boundary conditions of voltage souuce converterl (VSC)-HVDC transmission system with neighboring AC transmission lines are deduced and analyzed. Based on the converter switching function and modulation theory, the fundamental frequency equivalent circuit of converter from DC side point of view is obtained. The admittance matrix of deduced equivalent circuit can be combined with frequency dependent distributed transmission line two-port functions. This method can be used to calculate the induced fundamental frequency voltage and current, and then conduct the parametric analysis. The electromagnetic transient simulation PSCAD/EMTDC also proves that the deduced boundary conditions, which are only considering the fundamental component of VSC-HVDC converter, can be used to to analyze the electromagnetic induction between AC/DC transmission lines in the same right of way or in the same tower.
