| 摘 要： | 超/特高压同塔多回输电线路运行方式多样,线路间的零序互感会影响零序补偿系数和测量阻抗的大小,进而影响接地距离保护的整定范围。在理论推导的基础上,分析了在不同运行方式下线路互感对零序电流补偿系数的影响,给出了针对超/特高压同塔多回输电线路接地距离继电器零序电流补偿系数的整定方案。利用实时数字仿真器（RTDS）对1000k...

| Abstract: | For EHV/UHV multi-circuit transmission lines,zero-sequence mutual-inductions between lines impact zero-sequence current compensation coefficient and measurement impedance,as well as the setting range of earth-fault distance protection in different operation modes.The effects of the mutual-inductions between lines on the zero-sequence current compensation coefficient in different operation modes are analyzed with theoretic derivation,and the setting scheme of zero-sequence current compensation coefficient fo... |
