Abstract:
To study the rules of interference and protective measures on buried pipelines of high-voltage direct current (HVDC), the influence of different factors, including current into soil, soil resistance, damaged rate of coatings, and electrode-to-pipe distance, on pipe-to-soil potential deviation were simulated. Based on the simulated results, the fitted equations and interference judgment pattern were also obtained. The protective measures of insulation and cathodic protection can be performed for buried pipelines to prevent the interference, but the cathodic protection in the isolated area may become the stray current source of the other pipe section. This study can provide suggestions for the evaluation of interference and protective measures of pipelines of HVDC.
