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. |
