摘　　要：针对目前串联电容补偿系统测量存在的难点,本文通过分析串联电容补偿平台上电流互感器(TA)测量系统的干扰源和干扰路径,考虑串联电容补偿平台TA测量系统性能需求和工程实际,以及集中电子式TA测量系统相关功能模块的实现方式,设计一种集中电子式TA测量系统,采用冗余闭环控制的全激光供能技术及集中测量单元设计,提高了系统的可靠性,并在实际工程中得到应用。In view of the difficulties in the measurement of the current series compensation system,the interference sources and interference paths of the current transformer measurement system on the series compensation platform are analyzed.This paper introduces the realization of relevant functional modules of centralized electronic TA measurement system,and designs a centralized electronic TA measurement system.The reliability of the system is improved by using the full laser power supply technology with redundant closed loop control and the design of centralized measurement unit,and the application in practical engineering is realized.
