摘　　要：为了提高供电系统的功率因数,进行无功功率的补偿,本文设计了一种基于单片机的无功功率补偿控制器,该控制器以无功功率为控制量,精度高,还具有过压,欠流,自动,手动等功能。能够提高系统的功率因数,减少电能损耗,改善电能质量。该系统主要包括供电,单片机最小系统,电压电流和相位检测,按键输入,显示控制,继电器输出等模块。文中对其软硬件系统进行了较为详细的阐述。In order to improve the power factor of power supply system and compensate reactive power, this paper designes a kind of controller, it is based on MCU to compensate reactive power. The controller uses reactive power control as control target, with high precision, also has function such as over-voltage, owe current, automatic, manual, etc. It can improve the power factor of system, reduce power losses and improve power quality. This system mainly includes power supply, MCU minimum system, voltage current and phase detection, the key input, display control, relay output module, etc. The paper discusses the hardware and software system in detail.
