Analysis of Electromagnetic Influence Between High-voltage AC Transmission Lines and Buried Oil and Gas Pipelines(May 2018)

This paper also give some suggestions for the protection of electromagnetic influence. This paper shows computational analysis and evaluation methods of AC corrosion influence between high-voltage ac transmission lines and buried oil and gas pipelines. CDEGS simulation analysis is carried out on the engineering project which involve overhead 500kV and several 220kV AC transmission lines nearby buried oil and gas pipelines. The results shows different changes of disturbance voltage on nearby pipelines before and after the construction of 500kV AC transmission. This paper also give some suggestions for the protection of electromagnetic influence.
