基于IEC61850的变电站运行状态监测方法研究

Research on the Monitoring Method of Substation Operation Status Based on IEC61850

针对变压器在线监测的建设和运营,研究引入了IEC61850通信标准,并将其应用于智能变电站的状态监测中,同时在系统中引入了油色谱监测单元。结果表明,在横向对比中,该系统的监测上限延迟时间仅为180 ms,运行稳定性较高。此外,在油色谱监测中,两个主变压器油中的有害气体含量均在规定值内,说明研究所设计的变电站运行状态监测方法具有较强的可靠性,从而为电力企业提供全面、准确、及时的设备状态信息和管理决策支持。

In view of the construction and operation of the online monitoring of transformers,the IEC61850 communication standard has been introduced and applied to the status monitoring of intelligent substations.At the same time,the oil chromatography monitoring unit has been introduced into the system.The results indicate that in the horizontal comparison,the monitoring upper limit delay time of the system is only 180 ms,and operational stability is high.In addition,in oil chromatography monitoring,the harmful gas content in the oil of both main transformers is within the specified value,indicating that the operation status monitoring method designed by the research institute for substations has strong reliability,providing comprehensive,accurate,and timely equipment status information and management decision support for power enterprises.
