摘　　要：负荷密度的增长推动中压开关站在城市配电网承担日趋重要的角色。提高中压开关站的可靠性成为配电网企业近年来重视的课题。提出一种以可靠性为中心的网架结构,通过站间联络线提升中压开关站的安全冗余度,使其满足"N-2"安全准则,并介绍了配套保护与自动化配置、运行方式、故障恢复的动作逻辑,以及可靠性的理论测算结果。The increased load density promotes the importance of MV switching station in urban power distribution network, so enhancing its reliability draws the attention of urban power supply enterprises. This paper presents a reliability-centered structure design of MV switching station, which improves power source redundancy with tie lines between stations in accordance with＂ N-2＂ security guideline. Then further introduction is made about the supporting configuration of protection and automation, operation modes, failure recovery procedures and simulated calculation of the structure＇s reliability.
