摘　　要：研究了一种基于ARM7TDMI-S内核微控制器LPC2138的输配电线路的功率因数测控系统,该系统简化了外围电路。不仅实现了对功率因数的测量和数字显示,而且还能控制功率因数补偿装置进行适当调整。论述了该测控系统的基本工作原理,以及硬件配置和软件设计。Based on ARM7TDMI-S core LPC2138 microcontroller a monitoring system for the power factor of transmission and distribution lines is studied, which simplifies the peripheral circuits. It not only realizes the measurement and digital display of power factor, but also can control the power factor compensation device to make appropriate adjustment. In the paper the basis operating principles of the measurement and control system, and the hardware configuration and software design are described.
