摘要
通过对无功补偿原理和方式的分析研究,提出了一种基于高性能低功耗的AVR单片机ATmega128和高精度计量芯片ATT7022B的无功补偿控制器的实现方案,给出了电路组成、功能以及软件流程。该控制器能精确控制电容器组的投切,提高补偿精度,并能通过USB或RS-232/485串行口与上位机进行各种数据的通信。
With studying on the theory and mode of reactive power compensation,a low voltage reactive power compensation controller was presented.It was based on high-performance,low-power AVR microcontroller ATmega128 and high accuracy ATT7022B power/energy measurement IC.The composition circuits,function and the flow process charts of the software were introduced.The capacitors can be controlled accurately to improve compensation precision and the data can be sended to upper computer by USB or RS-232/485.
