Abstract
With the construction and development of high voltage transmission lines, the parallel erections of HVAC and HVDC transmission lines have emerged. The hybrid electric field under the parallel transmission lines should be accurately predicted in order to satisfy the requirement of electromagnetic environment. Besides, the coupling characteristics between AC and DC transmission lines should be carefully analyzed to well understand the interaction mechanism. Based on finite element method (FEM) and finite volume method (FVM), the distributions of electric field and space charges under the 750kV HVAC and the ±800kV HVDC parallel transmission lines are calculated in this paper. The coupling characteristics of surface electric field and space charges in flow field are analyzed. Besides, the influence of separation distances on the distribution of hybrid electric field and coupling characteristics are analyzed.
