Abstract
To provide a design basis for ultra-high voltage direct current,extra-high voltage alternating current,and DC grounding electrodes sharing the same tower,this study conducts simulation analysis on the electromagnetic environment of a hybrid voltage tower designed for a UHV project.The limiting values of various electromagnetic environment indicators for hybrid voltage same-tower transmission lines are determined.Calculations are performed on electric field intensity,ion current density,radio interference,and audible noise within the transmission corridor using the hybrid voltage same-tower reference model.Through controlled variable analysis,the impacts of four key factors on the electromagnetic environment are investigated:AC conductor arrangement,DC conductor polarity configuration,grounding electrode operation modes,and tower structural layout.Results demonstrate that the ground-level electromagnetic environment indicators of the reference tower model all meet specified limits,while the vertical spacing between conductors in hybrid voltage towers must satisfy insulation requirements.关键词
