Abstract :
A method to restrict the ion-flow field under the high-voltage direct-current (HVDC) transmission line by installing shield wire (SW) is analyzed in this paper. A reduced-scale platform is built up in the laboratory to check the effect of SW on decreasing the electric field and ion current density on the ground. The influence of SW on the ion-flow field is analyzed by an upstream finite volume method (FVM) and the calculated results match the measured ones well. A typical ± 800-kV bipolar HVDC transmission line is analyzed as an application, and it is shown that if the geometric parameters of SW are chosen suitably, the maximum ground-level electric field under the transmission line can be obviously decreased. In engineering design, it is an effective method to restrict the ion-flow field by installing SW under the HVDC transmission line.
