摘要:

为保证电子式互感器在实际长期运行中的可靠性和准确性，提出了一种基于IEC61850的电子式互感器在线监测与校验系统方案。该方案将电子式互感器集成了在线监测功能，实现电子式互感器状态的实时采集与传输。同时设计出电子式互感器在线校验装置，搭建电子式互感器在线校验系统架构，实现对电子式互感器准确度的实时校验。并将监测系统与校验系统融合一体，通过IEC61850标准协议与监控后台通信，形成对电子式互感器的全面实时检测。试验已验证该系统满足0.05级准确度要求，且该系统已投入实际应用，运行效果良好。

Abstract:

In order to ensure the reliability and accuracy of electronic transformer in actual long running period, this paper proposes an online monitoring and calibration system for electronic transformer based on IEC61850. The program integrates the function of online monitoring into the acquisition device of electronic transformer, and realizes the real-time states collection and transmission of electronic transformer. Meanwhile, it designs electronic transformer online calibration device, sets up electronic transformer online calibration system architecture, and realizes the real-time accuracy calibration of electronic transformer. The monitoring system and calibration system are combined into a compositive system, which communicates with substation monitoring system based on IEC61850 standard protocol. The whole system reaches a comprehensive real-time detection of electronic transformer. Experiment shows that the system satisfies the requirement of accuracy of 0.05 class, and practical application of this system has achieved good results.
