Designing and Modeling of On-line Monitoring System for Smart Converter Transformer

换流变压器在线监测系统(on-line monitoring system,OLMS)的建设是换流站智能化建设的重点,也是设备由"定期检修"过渡到"状态检修"的基础。本文分析了换流变压器在线监测系统的配置策略,结合IEC 61850标准的架构体系,提出基于IEC 61850标准的智能换流变压器在线监测系统总体结构;分析了监测系统的功能需求,结合IEC 61850第2版建立换流变压器在线监测智能电子设备(IED)的完整信息模型,新建了IEC 61850中没有的逻辑节点和监测数据。设计方案适合智能换流变压器在线监测系统的改造或新建。

To achieve a smart converter station, an on-line monitoring system （OLMS） for converter transformer is needed. Furthermore, it is the requirement for transition of maintenance strategy from ＇time-based maintenance＇ to ＇condition-based maintenance＇. Architecture of smart converter transformer OLMS based on the IEC 61850 is pro- posed through analyzing the structure of IEC 61850 and the scheme for converter transformer OLMS. Based on analysis of function requirement of OLMS, the function and device model for OLMS intelligent electronic device are built with the IEC 61850 edition 2.0, and new logic node and monitoring data are defined. The designed scheme is suitable for transformation or new of OLMS for smart converter transformer, which shows good reference significance and applica- tion value.
