Abstract
With the rapid development of high voltage direct current (HVDC) transmission technology, more and more buried pipelines may suffer from DC (direct current) interference from grounding electrodes of HVDC system. How to accurately realize the risks caused by HVDC interference in buried metal pipelines and effectively evaluate them have become the problems needed to be solved urgently. HVDC interference cases and indoor experimental research work in recent years are investigated and summarized. Meanwhile, the applications of numerical simulation to HVDC interference prediction and mitigation are introduced. Besides, the existing problems and developing directions in HVDC interference field are pointed out at the end of the paper. The paper could provide reference for the understanding and assessment of HVDC interference in actual production.
