Abstract

A numerical method to calculate the ion flow field in the vicinity of multi-circuit DC transmission lines is described. Details of the transmission lines such as bundle conductors and ground wires are taken into account in this simulation model. Deutsch assumption, a commonly used simplification in traditional numerical methods is eliminated. The ion flow field of a Â±500 kV HVDC project with bipolar lines on the same tower is simulated. The electrical field and ion current density on ground level are compared among different line arrangements.
