摘要
从结构设计、通信网络选择、FTU设计、上位机软件以及CAN总线在系统中的应用等方面阐述了辐射状配电网和环网开环运行配电网自动化系统方案 ,设计了基于CAN总线的现场通信网络 ,包括上位机和FTU的CAN接口 ,基于DSP +AT89C5 1双CPU结构的FTU的硬件 ,以及FTU的故障处理方式所用的算法 ,给出了分段开关具体的分闸逻辑和环网开关合闸逻辑及相应的FTU软件 ,还以VB6 0开发了上位机监控软件。实验和现场运行表明CAN总线造价低 ,可靠性高 。
This paper researches the scheme of distribution automation system for radiation structure distribution network and loop structure but with opening running distribution network. The text discusses on several aspects including the frame of total system, the choice of communication network, the design of feeder terminal unit, the software design of master computer and the application of CANBUS in the system. It designs the communication network based on CANBUS in detail, including the meeting units of master computer and feeder terminal unit and the hardware of feeder terminal unit based on double CPU structure with DSP+AT89C51. It presents the arithmetic of FTU's fault treatment and gives the disconnection logic of subsection switch and the closing logic of main ring switch. It designs the software of FTU also. It designs the master computer's software with VB6.0. The experiments of lab and on site operation prove that CANBUS has low cost but high reliability. CANBUS is fit for distribution automation system. This distribution automation system is a high quality and low price system.
