Summary:针对基于 RS485总线的功率因数分布式补偿系统设计，阐述了无功补偿控制的原理以及分布式补偿的工作原理，进行了基于单片机控制的主从机软硬件设计。按照适补原则，采用一定比例配置的电容器组，控制器检测每只电容器的网络地址、容量大小，根据需要补偿的无功功率，在所有电容器组组合方式中选一组最接近但补偿容量不超过的补偿方式进行补偿。实现了投切电容的智能化控制。

According to the power factor distributed compensation system design based on the RS485 bus,this paper made an exposition of the principle of the reactive power compensation control and that of the distributed compensa-tion,and designed the hardware and software of the master - slave machine based on the single chip microcomputer. In accordance with the principle of optimal repair,a certain percentage of the capacitor banks were configurated,the network address and capacity of each capacitor were detected by the controller. According to the reactive power nee-ding compensating,a set of compensation mode,which was closest to but not more than the compensation capacity, was chosen among all groups of capacitor combinations to compensate. Thereby the intelligent switching on - off con-trol for capacitance was realized.
