| 摘要: |
| 针对环网柜不易测量多路模拟量的特点，提出了一种基于数字信号处理器（DSP）的智能配电网环网柜馈线终端FTU（Feeder Terminal Unit）的设计方案。系统采用插槽式结构进行模块化设计，利用复杂可编程逻辑器（CPLD）进行信号调度，能够最多测量120路模拟信号，也可搭配开关信号共同使用，并且集成有供现场调试用的液晶显示屏。系统还研制了基于PC机的上位机调试软件，通过串口或网络进行通信，在PC机上可以方便地了解到线路的运行状态及历史数据等。 |

| Abstract: |
| As the RMU（Ring Main Unit） of intelligent distribution grid is difficult to measure multiple analog signals，a DSP-based FTU（Feeder Terminal Unit） is designed for it，which adopts the slot-type structure in modularized design，applies CPLD to dispatch signals，measures up to 120 analog signals or digital signals，and integrates LCD for site commissioning. The commissioning software is developed for PC-based superordinate computer，communicating via serial port or network. The line operating condition and the historical data can be displayed on the PC. |
