摘　　要：针对目前数量繁多的电能计量芯片进行分类分析,以ATT7026A、IDT90E23以及ADE7880为代表进行性能对比。ATT7026A芯片提供各分相、合相参数,但不提供各次谐波分析功能,且没有中断功能;ADE7880计算基波/谐波/总有功、基波/谐波无功,但不计算总无功,有短时谐波分析引擎,可选择特定谐波分析,且在2000:1的动态范围内对高次谐波的测量精度也能达到1%。90E36具有较宽的电能计量动态范围,且配备有傅里叶谐波分析引擎,可分析谐波次数达32次。对ADE7880的高精度谐波计量特点进行验证分析,为谐波电能表设计中的芯片选型提供参考依据。There are many kinds of energy metering IC on the market which can be represented by ATT7026A、 IDT90E23 and ADE7880.They are classified and compared in this paper.The ATT7026A can provide apart and total phase parameters,but not the each harmonic analysis,nor the interruption function.The ADE7880 with the precision of 1% to the high order harmonics in dynamic range of 2000：1,can provide the fundamental,the harmonic and total active power,the fundamental and the harmonic reactive power,while the total reactive power is not analyzed.The short time harmonic analysis engine embedded in the chip can give the characteristic of the selected harmonic.The 90E36 embedded with Fourier analysis engine has high dynamic range and can give the parameters of the harmonicthe order of which can reach 32.The high precise harmonic analysis characteristic of ADE7880 is tested,which can be take into consideration when designing energy meters.
