摘　　要：利用Motorola公司的8位单片机MC68HC908GP32和Analog公司的05年生产的最新电能测量芯片ADE7758设计一个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,完全满足未来分布式供电系统电能参数的计量要求。A bi-directional multi-functional electric meter is designed based on the 8-bit MCU MC68HC908GP32 which is produced by Motorola and the electric energy testing chip ADE7758 which is produced by Analog at 2005. It can judge the energy consuming direction of a system by the phase difference between the current and the voltage waveforms in the electric net. It can calculate the energy consumption or output energy of a system. This electric meter can be applied in the three-phase four-line system as well as the mono phase system. In addition to the former capabilities, this electric meter can be used to measure the other electric parame- ters in the electric net. It can fulfill the electric parameter measuring requirements in the future distributed electric energy supply system.
