为了提高配电网的安全性和可靠性,根据10 kV配电自动化的发展现状,研究并设计了应用于电力系统配电自动化网中的馈线终端装置(FTU)。以TI公司的TMS320LF2407为核心,介绍了FTU的主要硬件构成部分、软件流程。给出了模拟量调理电路、A/D转换接口、时钟接口等单元电路的设计实现方法。在实际中,系统能准确测量电压、电流、功率等物理量,并能迅速判断故障所在。
Abstract:
 In order to improve the security and dependability of distribution network,the feeder terminal unit(FTV),which is applied in the network of distribution automation in electric system,is researched and designed according to the development of distribution automation at present.It is centered on TMS- 320LF2407 produced by TI corporation.The hardware and software of the system are introduced mainly.The circuit of analog signals,the interface of AD converter and the interface of clock are mentioned.It can measure voltage,current and power exactly and judge where the faults lie in system operation.
