局部同塔双回直流输电线路的行波特性研究
Research on Travelling Wave Characteristics of Double-circuit HVDC Transmission Lines Partially on the Same Tower
摘要
Abstract
According to structural features of double-circuit HVDC transmission lines partially on the same tower,this paper makes theoretical and simulating analysis on refraction characteristics of travelling waves of voltage modulus at the demarca-tion points in different line segments. Then it analyzes characteristics of faulted travelling waves of double-circuit HVDC transmission lines in different line segments as single pole grounding fault occurs,and discusses influencing factors of the ac-tual engineering as well as summarizes effects on characteristic quantities of travelling wave protection. The research results indicate refraction and reflection of the demarcation point may cause reassignment of travelling waves and changes of ampli-tudes,which must be considered for analyzing action performance and studying new principle of travelling wave protection.关键词
