Popis:	It is of importance to assess the electromagnetic influcence of HVDC converter station on buried metal facilities of AC substations, fossil-fuel plants, windfarms and pipelines. Electromagnetic interference model was established based on the experimental measurement of soil resistivity and actual physical location. It was shown that the grounding potential rise (GPR) of Yijing 220kV substation, Banjing wind farm, Nanhuashan wind farm, Jiyangshan wind farm, Liugou wind farm and Limin wind farm exceeded the standard. The effects of distance, soil resistivity and injected current on GPR were also investigated. The results can provide reference significance for design and maintance of HVDC transmission engineering.
