智能变电站监测端口系统设计及其实现

Design and Realization of Intelligent Substation Monitoring Port System

建立了能够对整个智能变电站控层的设备运行情况进行监测的系统,在提高监测效率的基础上优化了诊断修复的模式,能够结合设定的异常故障阈值以及特征库,完成异常报警功能,还可以利用告警直传的方法来完成上传调度的过程。客户端由硬件监测模块和业务监测模块组成;服务端可以完成参数计算、故障分析以及警报信息传输的功能。选择数据变化作为分析依据,构建得到具备周期动态变化特征的轮询方案。根据站控层设备产生的现场异常统计结果与故障记录,监测系统可以产生大量异常数据,由此构成最初的故障参数库。利用特征库完成周期轮询监测,再通过智能分析获得各项监测以及诊断参数。

A monitoring system is set up for the running status of whole intelligent substation control layer equipment.It can improve the efficiency of monitoring and repair on the basis of optimizing the diagnosis model,the abnormal fault setting threshold and characteristic library.It can also complete the abnormal alarm function,and use the alarm to complete the upload scheduling process.The client terminal consists of hardware monitoring module and business monitoring module.The server can complete the function of parameter calculation,fault analysis and alarm information transmission.Data changes are selected as the basis for analysis,and a polling scheme with periodic dynamic change characteristics is constructed.According to the statistical results of on-site anomalies generated by the equipment in the station control layer and the fault records,the monitoring system can generate a large number of abnormal data,thus forming the initial fault parameter database.The feature database is used to complete periodic polling monitoring,and then the monitoring and diagnostic parameters are obtained through intelligent analysis.
