Abstract:

 This paper studies the electromagnetic environmental problems of 1 000 kV UHVAC single-circuit transmission lines. Including frequency electric field, frequency magnetic fields, radio interference and audible noise.Combined the existing assessment limit of electromagnetic environmental, the existing calculation methods of electromagnetic environment were summarized. Taking the north of Zhejiang to Fuzhou UHV transmission line as example, this paper calculated the electromagnetic environmental indicators for different wire structures, and recommended the suitable wire type and split numbers for UHVAC single-circuit transmission lines. Finally, the factors affecting the electromagnetic environment analysis, the influence of different factors on the electromagnetic environment effects comparison, the results will play a guiding role on the future UHV single-circuit design.
