摘　　要：介绍了一种基于高速单片机C8051F120的无功补偿控制系统,该系统能够实时准确地采集电压、电流,通过FFT变换计算出各相关电量参数,投切适当的电容入网,达到提高功率因数的目的,与PC机之间通过RS485和GPRS进行通信,可实现近端和远程监控。主要对系统的硬件电路,和投切控制算法进行了详尽地分析。The paper introduces a reactive compensation control system based on high speed MCU C8051F120. This system can sample voltage and current in real- time and correctly. The sampled data are processed by the FFT algorithm. After each related parameter acquired, it can improve power factor by switching on or off capacitances. In order to short-range and long-distance controlling, it can communicate with computer by RS485 and GPRS. The paper also analyzes the hardware circuit of the system and the switching control algorithm.
