一种高精度电力参数测量方法及实现

Accurate Measurement Technology of Electric Power Parameters ans Iits Realization

给出了一种采用模拟采法器、积分器、８０９８单片机构成的电力参数测量方法，该方法运用了双料式Ａ／Ｄ转换的基本原理。将模拟电压的测量转换为时间的测量，从而实现了电力参数的高精度测量。

A measuring circuit of electric power parameter is introduced, which consists of an analog multiplier, an integrator and an 8098 single chip microcomputer. With the basic principle of dual-slope A/D converter, the measurement of voltage is replaced by the measurement of time so that the electric power parameters can be accurately measured.
