摘要：

This paper proposes an electrode line fault supervision strategy based on the high-frequency voltage standing-wave ratio (VSWR). The paper analyzes the VSWR from theoretical side of its characteristics of the lossless transmission line to the numerical characteristics of the VSWR under different electrode line operation modes. On the basis of VSWR of the high-frequency signal, the electrode line fault identification criteria are obtained. The effectiveness of the impedance supervision strategy proposed in this paper was verified through the PSCAD simulation. From the discussion of the simulated results, the proposed strategy can reliably identify the electrode line fault and has a certain anti-fault impedance capability.
