摘　　要：为了开展特高压变电站电磁环境建模方法和预测计算的系统研究工作,基于矩量法,采用CDEGS软件对特高压变电站的工频电磁环境进行了预测研究,着重分析了变电站内线路巡视走廊和保护小室区域以及变电站外距围墙20m处的工频电场和工频磁场。计算结果表明:晋东南变电站站、南阳开关站和荆门变电站除站内TA、TV上方连接管母线以及HGIS下方最大工频电场强度超过了国际非电离辐射防护委员会(ICNIRP)导则规定的10kV/m的职业曝露限值外,其它各项计算结果均低于相应标准限值。In order to carry out research on the method of UHV stations electromagnetic environment modeling and prediction computation, this paper, based on the method of moment, simulated the steady-state electromagnetic disturbance of all voltage levels in UHV substations by using a software of CDEGS, emphatically analyses the power frequency electric-field and power frequency magnetic-field at the circuitry aisle and the relay cell zone as well as 20 m away from the wall of UHV substations. The simulation results illustrate that： the maximum power frequency electric field at the circuitry aisle of Jindongnan substation, Nanyangare substation and Jingmen substation appear in the tubular generatrix which connect TV and TA, as well as the space below HGIS. The maximum power frequency electric field of this three stations are both beyond the occupational exposure limit 10 kV/m; The results of other power frequency electric field are all lower than the corresponding standards; the maximum power frequency magnetic field at the circuitry aisle and the relay cell zone are all lower than the occupational exposure limit and electrical and electronic equipment immunity standard limit.
