In this paper, an upwind finite element (FE) based algorithm devoted for the computation on the ion flow field of bipolar high voltage direct current (HVDC) transmission lines. The choice of initial charge density value on conductor surface is discussed to satisfy the requirement of bundle conductor computation. Non-reflective boundary condition is introduced to improve the computational efficiency...
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 ??500 kV HVDC project with bipolar...
