摘要
随着电力系统电量的日益扩大和电压运行等级的不断提高,传统的电量检测系统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成软件部分的设计以及仿真,这成为本次设计的一个很大的遗憾。

Summary
With the growing electricity power system and the increasing level voltage operation, the traditional power detection system exposes more and more ings, 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 theory parative power of three parts; followed by an overview of the Hall sensor works and technical specifications of the work; Finally, a brief introduction of this design of the hardware system design, which includes a control circuit, chip puter AT89C51 choice, ADC0809 analog-digital conversion part, stand-key keyboard input section, LED static display some aspects of the design. Since I could not very well limited ability plete the software part of the design and simulation, which became this design a lot of regret.
