变电站风险数据监测与智能运维技术的研究

Research on Substation Risk Data Monitoring and Intelligent Operation and Maintenance Technology

通过对变电站各电力二次屏柜微环境瞬态过电压、操作过电压等风险数据的实时监测,及时发现过电压风险隐患,为数据丢包、设备误动、设备故障原因提供分析依据,通过数据分析、特征提取实现对二次系统信息化、现代化的科学管理,实现智能决策和智能运维,及早发现故障,提高运维效率,避免电网设备遭受过电压冲击损坏造成的设备故障,从而最大程度上减小设备损坏带来的有形经济损失和城市大面积停电带来的无形经济损失。

Through the real-time monitoring of the risk data such as transient overvoltage and switching overvoltage in the micro environment of each power secondary panel cabinet in the substation,the hidden dangers of overvoltage can be found in time,and the analysis basis for data packet loss,equipment misoperation and equipment failure can be provided.Through data analysis and feature extraction,information and modern scientific management of secondary system can be realized,and intelligent decisionmaking and intelligence can be realized it can be used for operation and maintenance,find fault as soon as possible,improve operation and maintenance efficiency,avoid equipment failure caused by overvoltage impact damage of power grid equipment,so as to minimize tangible economic loss caused by equipment damage and intangible economic loss caused by power failure in large area of city.
