基于ARM的智能馈线终端研究

Research of Intelligent Feeder Terminal Unit Based on ARM

提出了基于 LPC2292和 CAN 总线的智能馈线终端设计方案,逻辑部分通过 CPLD 实现,便于后期的功能扩展和升级。该终端不需完全依赖通信网络便可实现故障判断、处理,相邻终端之间通过 CAN 总线网络实现故障信息实时共享,可快速准确的将故障区段定位,智能隔离故障区段并恢复健全区段的供电。完成了智能馈线终端的硬件、软件设计,并针对终端所处的恶劣工作环境,进行了相应的抗干扰设计,在山西某10kV 线路测试期间运行正常。

A new scheme of intelligent FFU based on LPC2292 and CAN bus is proposed, whose logic unit is achieved by CPLD （Complex Programmable Logic Device）, so the expansion and upgrading of the function can be done easily. Intelligent FFU proposed in this paper can achieve fault judgment and processing not relying entirely on communication net. Based on real-time information sharing through CAN bus between adjacent FFUs, we can locate fault section accurately and isolate the fault line section and restore power supply to unfaulted line sections intelligently. Design of hardware and software were completed. Corresponding anti-interference measures are designed for its poor working environment. It runs normally during the test period in 10kV power line of Shanxi.
