基于故障录波数据的变电站故障分析系统

利用故障录波与保护信息,通过信息收集、筛选、融合,提取出能够直接反映事故特征的关键信息呈现给变电站运行值班人员,运行人员依据信息可进行事故分析;将故障和非故障设备关键信息进行综合,便于事故分析和处理;将变电站事故的初判信息按照其重要程度进行筛减和分类,将最重要的信息第一时间传送给调度中心,调度人员可以及时获得直观、有价值的信息,对电网的运行作出快速合理地调整,为电网的安全控制提供有效手段.

Substation Fault Analysis System Based on Fault Recorder Data

The system presented in this paper can get key characteristic of fault through information collecting,information filtering and information fusing based on fault recorder data and protection information.The operator can make the fault reason clearly and quickly by the key characteristic.The system will filter and class the original judgment information,the send the most important information to dispatch center in the first time.This system offer efficiency method to protect power grid safety.
