摘要
指出平行线路较强的电磁感应和电容耦合,对输变电设备、二次保护、系统运行均产生较大影响。针对不同平行输电线路结构,阐述了平行输电线路的定义,并按电压等级、性质对其进行分类。分析了平行输电线路对电网的主要影响因素,从平行输电线路系统分析技术研究、500 kV交流平行输电线路感应问题的研究等六个方面综述了平行输电线路规划、建设、设计、运行中的相应对策。
To take full advantage of line corridors,Our country popularized line types like double lines on the same tower and compact lines,Formed many parallel transmission lines which contain High-Low voltage,AC-DC voltage line corridors.Compared with the conventional transmission line,the more serious electromagnetic coupling and capacitive coupling on the parallel transmission lines case many problems of system operation,protection and so on.Arccordding to various combinations of parallel transmission line structure,this paper cleared the definition of Parallel transmission lines,Analyzed the main factor,General descriped the corresponding countermeasures to parallel transmission line for the planning,design,construction and operation.
