This report refers to the activities performed in the frame of PRCI project on the evaluation of interference risk from high voltage power lines (HVDC) on buried pipelines. There exist different types of HVDC systems and configurations and only some of them may affect pipeline corrosion and safety.
First, a literature study was performed to identify the various HVDC system configurations and operational conditions, to define the corrosion and safety threats on pipelines and the parameters influencing the interference level. Next, simulations were performed to understand how the operational...
First, a literature study was performed to identify the various HVDC system configurations and operational conditions, to define the corrosion and safety threats on pipelines and the parameters influencing the interference level. Next, simulations were performed to understand how the operational conditions of the HVDC system, the pipeline properties, the cathodic protection settings and the soil conditions determine the magnitude of DC stray current corrosion and voltage induced safety risk. Lastly, industrial cases were simulated and mitigative measures were proposed.
Guidelines are proposed for estimating the risk associated with HVDC lines.
