摘　　要：合并单元装置作为智能变电站的重要组成部分,能够将常规站传统的模拟量转换为智能站保护装置、安自装置及测控装置可接收的光量。但当合并单元装置异常时,如果采取的处置措施不当,可能会影响站内保护装置的正常运行,甚至会导致保护装置误动作致使故障扩大化。在总结合并单元异常和检修机制的基础上,对在合并单元异常时,保护装置该如何正确处理进行探讨,进一步降低对一次系统的影响,提高电网运行可靠性。As an important component of intelligent substations,the merging unit device can convert traditional analog signals of conventional stations into the amount of light that can be received by intelligent station protection devices,stability control devices,and measurement and control devices.But when the merging unit device is abnormal,if the appropriate disposal measures are taken,it may affect the normal operation of the protection device in the station,and even cause the protection device to malfunction and expand the fault.On the basis of summarizing the abnormal and maintenance mechanisms of merging units,this article explores how to correctly handle the protection device when merging unit abnormalities,further reducing the impact on the primary system and improving the reliability of power grid operation.
