摘要
通过对相同输电导线在不同布置方式、不同子导线分裂形式和不同电压等级下线路电抗、输送功率及投资变化的比对分析,指出在35～110 kV中压供电系统中采用相分裂输电技术可以有效降低线路电抗,降低线路电晕损耗和对无线电的干扰。该技术的应用和推广是改善和提高区域地区供电系统架空输电线路单位输电走廊传输能力的有效途径,具有良好的应用前景和显著的社会经济效益。
Through comparison and analysis on variation of line reactance, transmitted power and investment of the same power transmission conductors in the different arrangement forms, different sub-conductor split forms and different voltage levels, it shows that phase split power transmission technology adopted in 35-110 kV medium-voltage power supply system can effectively reduce line reactance, line corona loss and radio interference. Application and promotion of this technology is an effective way to improve and enhance transmission capacity of unit power transmission corridor of overhead transmission line of regional power supply system, which has a good application prospect and significant socio-economic benefit.
