摘要
针对箱式变电站(简称"箱变")监控系统实时性差、功能不健全等问题,设计了一种基于ARM与DSP的箱变智能远程监控系统。给出了该系统的硬件框图和工作原理图,对模拟量采集、开关量输入输出等模块进行了设计;在研究主程序以及模拟量、开关量、GPRS通信等流程的基础上,开发了箱变智能远程监控软件,实现了环境参量、电气参量和开关量等实时监控以及数据查询、故障预警、能效分析等功能。运行结果表明,该系统具有实时性强、功能全面、稳定性高等特点,对实施防御性维护、提高供电质量以及节能降耗等都具有重要意义。
Aiming at the problems of poor real-time performance and imperfect functions of monitoring system for box-type substation, an intelligent and remote monitoring system of box-type substation based on ARM and DSP is designed. The hardware block diagram and the working principle diagram of the system are given, and the modules such as analog acquisition and switch input/output are designed. On the basis of the flow diagrams including main program, the analog quantity, the switch quantity and the GPRS communication, the intelligent and remote box-type substation monitoring software is developed, which realizes the real-time monitoring of environment, electrical and switching parameters and other functions, such as data query, fault early warning, and en-ergy efficiency analysis. The experimental results show that the system has the characteristics of real-time, multi-function and high stability, which is of great significance for implementing defensive maintenance, improving power supply quality, saving energy and reducing consumption.
