基于单片机的电量检测-学位论文.doc

暴露出越来越多的缺点，难以满足现代电网向自动化、数字化发展的需要。本文首先

系统的阐述瞬时无功功率理论计算方法，其中由瞬时有功功率和无功功率、瞬时有功

电流和无功电流和瞬时无功功率理论和传统功率理论比较三部分组成；其次概述了霍

尔传感器的工作原理和各项工作技术指标；最后，简单介绍本次设计硬件系统的设计

方案，其中包括控制电路、单片机 AT89C51的选择、ADC0809模数转换部分、独立式

按键键盘输入部分、LED 静态显示部分方面的设计。由于本人能力有限没能很好的完

With the growing electricity power system and the increasing level voltage

operation, the traditional power detection system exposes more and more

shortcomings, it is difficult to meet the modern grid automation, digitization

development needs. This article first systematic exposition of the

instantaneous reactive power theory calculation method in which the

instantaneous active and reactive power, the instantaneous active current and

reactive current and instantaneous reactive power theory and the traditional

aspects of the design. Since I could not very well limited ability to complete

the software part of the design and simulation, which became this design a

lot of regret.
