浅谈110 kV双电源联络线“远跳”及“母差停信”功能的应用

摘要

Taking PSL621and ISA-311G as the example,this article elaborated the principle of remote tripping and bus differential protection stops sending letters of 1 1 0 kV double power supply lines of communication,and introduced the function application and the realization.Finally,for 1 1 0 kV double power source lines of communication,when dead area failure and the bus failure,it proposed several matters needing attention to ensure fast and reliable removal on both sides.%文中以PSL621和 ISA-311G为例阐述了110 kV双电源联络线的“远跳”及“母差停信”原理，并对其功能的应用和实现作了相应的介绍，最后针对110 kV双电源联络线线路死区故障及母线故障时，确保两侧快速可靠切除提出了几点注意事项。
