Research Progress on Interference and Protection of Grounding Electrodes of HVDC Transmission on Buried Pipeline
Abstrak
With the increasing number of high voltage direct current(HVDC) transmission projects in China，the issue of interference from HVDC system grounding electrodes on buried metal pipelines has become increasingly prominent.In order to conduct accurate research and analysis as well as protection assessment for the interference issue，this paper surveyed the research methodologies and influencing factors associated with HVDC system interference in recent years.The interference and corrosion patterns on pipelines were analyzed from four aspects: on-site field tests，laboratory simulation experiments，numerical simulation techniques and influencing factors.Meanwhile，the stray current protection technologies currently commonly used in HVDC systems in China were summarized，and their advantages，disadvantages and applicable scopes were elaborated.Finally，the research directions of stray current interference and protection were prospected.
