摘    要:半波长交流输电线路输送距离长、电压等级高,传统继电保护方案不能满足要求.文章考虑线路分布参数特性,采用均匀传输线特性方程,结合对称分量法,对半波长线路区内外故障特征进行了理论分析,仿真实验表明理论推导结果与实际情况基本相符.根据半波长线路的故障特性,文中提出一种基于贝瑞隆线路模型的适用于半波长交流输电线路的电流差动保护...

关 键 词:半波长交流输电  贝瑞隆模型  继电保护  电流差动保护

Abstract:Due to its features in long transmission distance and high voltage grade,traditional relay protection scheme cannot meet the requirement of half wave-length AC transmission(HWACT).Considering distributed parameter characteristic of half wave-length AC transmission line,by use of the characteristic equation of uniform transmission line and integrating with symmetrical component,the fault characteristics of HWACT line inside and outside the protction zone are theoretically analyzed,and simulation results show...
Keywords:half wave-length AC transmission  Bergeron model  relay protection  current differential protection
