摘　　要：在介绍ADE 7758多功能芯片特性的基础上,提出一种新型电网监测系统设计方案。该方案以计量芯片ADE7758进行硬件电路设计,以C8051F020单片机作为系统处理器设计了相应的测量系统软件,并对ADE7758的校准进行了研究。用三相精密测试电源对系统的测量精度进行了实验论证。实验结果表明:该仪表具有较高的测量精度,可以满足电能测量的精度要求以及电力设备实时监控方面的要求。A new design of monitoring system was given based on the introduction of ADE7758 poly phase multi-function energy metering IC. ADE7758 was used to measure IC in the hardware design, and the single chip C8051F020 was used as the processor in this system. Then how to calibration the ADE7758＇s register was introduced. Its measurement accuracy was verified by the three phase precision test power equipment, and the result shows that the measuring instrument has higher measuring accuracy. Its high accuracy meets the requirements of energy metering and real-time monitoring equipment.
