Abstract
In allusion to calculation on nominal electric field of high voltage direct current (DC)transmission lines,this pa-per takes ±500 kV high voltage DC transmission line from YichangLongquan to Changzhou Zhengping for an example and uses finite element analysis software COMSOL Multiphysics to establish a bundled conductor-overhead ground wire model,a simple bundled conductor model and an equivalent conductor-overhead ground wire model according to common simplified calculation method. It carries on simulation for these three models and takes the bundled conductor-overhead ground wire model as reference for comparing distribution of nominal electric field of different models. Finally it concludes that the o-verhead ground wire has slight influence on nominal electric field around DC transmission lines,which means it is feasible to ignore the simplified model of overhead ground wire in engineering application. The simplified model for equivalent conduc-tor is not suitable for analyzing electric field near to lines while it is suitable for analyzing electric field of regions far away from lines and has reduced calculating amount.关键词
