基于Deutsch假设法同塔高压/特高压直流输电线路地面合成场强研究 [PDF]
全球能源互联网, 2018 采用Deutsch假设法，研究了不同组合架设方式下同塔双回高压/特高压直流输电线路地面合成场强的分布特性。结果表明：Deutsch假设计算结果与实测结果较吻合，适用于双回直流线路的预测。高压/特高压直流线路同塔双回架设时，因空间离子流场的相互影响，地面合成场强分布与塔型和导线布置方式有较大关系。±800 kV特高压直流线路位于上层、极导线采取+-/-+方式布置时，地面合成场强最大值相比采取-+/-+方式布置增加了17%；±800 kV特高压直流双极线路位于杆塔同一侧、极导线采取++/--方式布置时 ...
