配电网终端数据采集器的设计

Design of Terminal Data Acquisition System for Distribution Network

设计了一种利用AVR单片机实现的配电网终端自动数据采集器,主要用于检测配电网中柱上开关、变压器和小区变电站的电压、电流、电量和功率因数等参数。由于设计采用了专用电能参数计量芯片和高速的AVR单片机来实现数据的采集,因此,满足了系统的多任务及实时性要求。本设计提高了配电网的自动化程度。

An automatic data collector realized by using AVR microcontroller in distribution system terminal unit was designed. It was mainly used to detect the parameters of column switch, transformer and area substation in distribution system including voltage, current, quantity of electricity, power factor, and so on. Owing to the adoption of the appropriative chip to measure the parameters of electrical energy and the high-speed AVR microcontroller, the design satisfied the system with muhitasking and real-time. The design increased the degree of automation of distribution system.
