| 摘 要： | 介绍利用Motorola公司的8位单片机MC68HC908GP32(以下简称GP32)和Analog公司的电能测量芯片ADE7758设计的多功能双向电能计量表。它可以根据电网上的电流与电压相位夹角大小,来对一个系统使用电能的方向进行判断,从而可以计量一个系统的消耗或者输出电能,该表既可用于三相四线系统也可用于单相系统。除此之外,该电表还可以测量电网其它电气参数:比如有用功率、电流有效值、电压有效值等。该电表可以应用在小型发电系统上及其它相关应用领域。另外,该电表具有良好的人机界面,具有高低电压运行及掉电保护等功能。

| Abstract: | There is an introduction of a design of bidirectional and multifunctional electric energy meter,which is based on 8-bit MCU,MC68HC908GP32,and multifunctional energy metering IC,ADE7758.Judged by the phase difference between the current and voltage waveform,the special digital energy meter can measure the electric energy both used and generated by a certain system,such as solo-electricity system.A friendly human-machine interface is included in the meter.Besides the special functions above,the meter is also able to measure active power,RMS of both voltage and current,and protect such key data as bidirectional energy amount in case of the unwanted power-down. |
