基于组态王的配电网监测系统研究

Research for Distribution Monitoring System Based on Kingview 

摘要:

针对6/10 kV配电网,为减少电网故障对用户和设备造成的损失,实现对电网参数的实时监测与故障预警,设计了基于组态王与RS-485总线配电网参数在线监测系统;电网参数经6/10 kV互感器获取传送给电参数变送模块,变送器将信号转换成支持ModbusRTU通信协议格式,通过RS-485总线将数据采集、上传到监测计算机;上位机监测系统采用组态王软件结合SQL关系数据库,实现实时电压、电流、频率、功率、电能的显示、存储、报警、管理等功能;经调试运行证明该系统方案是正确的、可行的。

Abstract:

In order to reduce the loss of the power grid fault caused to users and equipments. An online monitoring system for 6/10 KV electrical parameter is designed based on the KingView and RS-485 Bus. Network parameters via transformer detection and decompression then sent to the intelligent voltage / current transducer, intelligent Transmitter secondary buck and convert the signal to support 485 formats, at last by RS485 BUS uploaded the collected data to the monitoring computer. PC monitoring system using configuration software configuration king, by the KingView and SQL relational database configuration combined to achieve real-time data display, storage, alarm management. After commissioning, operation results show that the system is correct and feasible.
