一种由AT89C2051单片微机实现的功率因数补偿装置

介绍一种用于电力配电系统的旨在提高功率因数的智能型功率因数补偿装置，以AT89C2051单片微机为核心，自动完成电力供电线路的参数测定、运算及功率因数自动补偿控制。提出以可控硅全控桥作为执行部件，实现无级平滑容性补偿的方案，一改传统的机械触点式多组开关进行电容器分组切换投入进行补偿的方法，具有一定的实用性。

A New Type Device of Power-Factor Compensation Based on AT89C2051 Single Chip Micro-Computer

In this paper, an intelligent device of power-factor compensation for improving power-factor in the electrical power distributing system is introduced. The practical device based on AT89C2051 single chip micro-computer has a serious of automatic functions, such as :the measurement and calculation of the parameter of electrical power on line as well as the control of power-factor compensation. The scheme of stepless control and capacity compensation proposed by the paper can be realized by the thyrstor convertor as executive parts in the system, which can replace the traditional compensation method that capacitor cells is switched by switches of mechanic contact.
