摘要
配电变压器是配电网络中最重要的电力设备,其运行状态关系着配电网络的稳定。配电变压器监测终端(TTU)是配电自动化系统中的重要部分,保障配电系统的可靠运行。针对配电变压器运行状态的远程实时监控需要,依据GSM的通信协议,设计了基于单片机MSP430F449和GSM短信平台的配电变压器远程监控系统。经过模拟运行表明,该系统建网方便、无需布线和几乎不受区域限制,一次性投资少,日常运行费用低,能够准确测量出配电变压器的各种电参数,实现监控终端与上位机之间准确的数据传输,运行稳定。
Distribution transformer is the most important electric power equipment in the distribution network, of which running status relates to the stability of distribution network. The transformer terminal unit, naming TTU, is an important part of distribution automation system and guarantees the security of distribution automation system. In order to realize remote monitoring for the real time status of transformers, the transformer remote monitoring system based on MSP430F449 and GSM fiat was designed according to the communication protocol of GSM. The result of simulation shows that parameters of the transformer could be measured accurately and the data transmission between supervise terminal and upper-controller is precise and the system is stable. The building of network is convenient, wireless and free of regional restriction. One time investment is small. The cost of day-to-day running is low.
