N2 - Aiming at the inter-pole coupling effect of HVDC transmission line, a faulty pole selection scheme based on the electrical variables of single pole is proposed. The characteristic analysis of inter-pole coupling shows that, the coupling effect is related to the frequency of electrical variables: the higher the frequency is, the more obvious the coupling effect is. Theoretical spectrum analysis and simulative results show that, the content of low-frequency signals in the electrical variables of healthy pole is much lower than that of faulty pole, based on which, a faulty pole selection scheme based on the electrical variable of single pole is proposed and its criterion is given. The feasibility and validity of the proposed scheme are verified by the simulative results and field-recorded data.
