基于GPRS通信技术的单相配变监测系统设计

Design of Single-Phase Distribution Transformer Monitoring System Based on GPRS Communication Technology

为了保证单相配电系统安全稳定运行,讨论了GPRS通信技术用于单相配变监测系统,介绍了一种基于GPRS网络虚拟数据专网(VPN)方式的单相配电变压器实时监测系统设计方案。系统可有效地应用于单相配电系统中,实现单相配电变压器运行数据实时监测、远程数据传输、及时报警等功能,同时可完成历史事件查询、历史数据分析等功能。

For the guarantee of the single-phase distribution system＇s safe and stable operation, this paper discussed the advantages of GPRS communication technology in single-phase distribution transformer monitoring system, and introduced a design scheme of single-phase distribution transformer monitoring system based on GPRS and VPN communication technology. The scheme contains the selection of GPRS and VPN communication technology,the design scheme of the monitoring master station based on the modes of C/S and B/S, the design scheme of the single-phase distribution transformer monitoring terminal based on the dsPIC33FJI2$GP206 and MCP3909. The system can be applied effectively in single-phase distribution system, to realize functions of real-time operation data monitoring, remote transmission of monitoring data, immediate alarm, etc. The system also can finish the query of historical event entries and the analysis to historical data.
