摘　　要：由于串补成套装置分设备较多,设备性能特殊,故而造成了检修工作量大,耗时长,效率低等问题。为了解决这些问题,本文结合我国首套750 kV日月山—海西—柴达木输电线路串补工程的特点,提出了一种750 kV串补关键设备状态自评估系统设计方案,通过计算分析串补日常的运维检修数据给出电容器组、金属氧化物限压器、火花间隙、阻尼装置等关键设备的状态评估结论。从而可依据此状态评估系统制定出更精准、更高效的检修工作计划。该方案对实现串补检修工作的精细化控制、降本增效有极大的参考价值。Due to the large number of sub⁃equipment and special equipment performance,the series compensation(SC)overhaul has caused problems such as large workload,long time⁃consuming and low efficiency.In order to solve these problems,this paper combines the characteristics of China’s first 750 kV Riyueshan⁃Haixi⁃Caidamu transmission line SC project,and proposes a 750 kV SC key equipment state self⁃assessment system design scheme.The daily operation and maintenance data gives the status evaluation conclusions of key equipment such as capacitor banks,MOV,GAP,and damping devices.Therefore,a more accurate and efficient overhaul work plan can be formulated based on this status evaluation system.This solution has great reference value for achieving fine control of SC overhaul and maintenance work,reducing costs and increasing efficiency.
