Description: As the energy metering industry converts from electromechanical meters to more-accurate solid-state meters, power-system designers have a chance to incorporate new features that weren’t previously possible. In demand now are solid-state meters that measure energy more accurately than electromechanical meters, incorporate multiple-rate billing, and are capable of being read remotely by the utility company. This article describes how the AD7755 Energy Meter integrated circuit could be used in three-phase energy metering with power outage detection and measurement backup, and remote, automated, multiple-rate metering.

级精度要求的算法，同时扩展了谐波分析功能。系统概述为：三相电压、电流
AD 采样，采样数据通过串口送至处理器(DSP)，由 DSP 对采样数据作电参数计
量和谐波分析，处理结果通过定制 LCD 显示，并通过脉冲口发出有功、无功校
表脉冲。DSP 采用 ADI 公司的 BLACKFIN531-16 位定点芯片，最高处理能力可
达 800MIPS， 采样芯片为 16bit 的AD73360， 支持六通道同步转换， 无同步误差。数字化、高精度、创新性和可扩展性是本项目的特点，准同步采样算法和谐波分
析是本项目的新颖之处。-Make full use of the DSP powerful signal processing ability and the modern numerical analysis method. Design the
Watt-hour meter front sampling and measuring module of hardware, as well as a set of accord with national standard GB/T 17883-17883 of 0.2 S
Accuracy of algorithm, at the same time extend the function of harmonic analysis. System overview: three-phase voltage and current
The AD sampling, sampling data via a serial port sent to the processor (DSP), electric parameter meter by DSP of the sampling data
Quantity and harmonic analysis, process the results with a custom LCD display, and through pulse mouth making active and reactive power
Table pulse. DSP adopts BLACKFIN531 of ADI company- a 16-bit fixed-point chip, the highest processing capacity
Up to 800 MIPS, sampling chip AD73360 for 16 bit, supports six channels synchronous conversion, no synchronization error.
