- Abstract:
- Conductor surface electric field strength is the determining factor for radio interference,audiblenoise and corona loss of ultra-high voltage direct current(UHVDC)transmission line,so it is particularly im-portant to accurately calculate the conductor surface electric field strength. The study of factors on the surfaceelectric field at home and abroad is more less. Therefore the investigation is carried out on the influence of sub-conductor number,sub-conductor cross section,split spacing and conductor height on the conductor sur-face maximum field strength,which used charge simulation method by set 12 charge simulation in each sub-conductor. The program is written in MATLAB language to calculate and simulate,and each variable affectingon surface electric field strength is resulted quantitatively,which provides an important theoretical basis for en-gineering construction how to select the structural parameters of conductor.
