Challenges in Mitigating AC Interference in Remote Areas

Picture for Challenges in Mitigating AC Interference in Remote Areas
Available for download

An AC interference study was conducted in 2015 after the installation of a 240 kV powerline. Risk of AC corrosion was indicated.  Describe are both the challenges and the solutions, including the design of a temporary mitigation system allowing energization of the powerline at reduced power.

Challenges in Mitigating AC Interference in Remote AreasM. Luk P. Eng.D. Hebb EITCorrosion Service Company Limited9-280 Hillmount Rd.Markham ON Canada L6C 3A1E. Gudino P. Eng.Chad Khattar P.Eng.TransCanada Pipelines Limited450 – 1st Street SW CalgaryAB Canada T2P 5H1An AC interference study was conducted in 2015 following the installation of a new 240 kV powerline in a remote area of Alberta Canada.The calculations indicated severe risk of AC corrosion for paralleling pipelines and safety hazards for pipeline personnel especially under fault conditions.A mitigation system was designed consisting of more than 10 km of bare copper mitigation wire; however due to site conditions (i.e. winter access only) it was not practical to install the system prior to the scheduled powerline energization.The paper describes both the challenges and the solutions in this project including the design and optimization of a temporary mitigation system allowing energization of the powerline at reduced power.
