Analysis of electricity measurement accuracy driven by carbon neutrality

In response to the problem of low accuracy in traditional power metering equipment. Driven by the goal of carbon neutrality, This article has designed a high-precision carbon meter based on Time Division Multiplier (TDM) energy metering chip. The design scheme adopts frequency domain analysis method to quantify the errors in TDM structure, eliminating phase shift errors using a modulator with a phase compensation branch; Simultaneously constructed a dynamic carbon emission measurement model for a stepped electric energy meter group, Its principle is to divide the output of the power meter group into multiple intervals, with different carbon emission factors in each interval, to simulate the fluctuation of carbon emission factor values under different output states of the power meter group, and accurately calculate the total carbon emissions of the system; Finally, use LED to display all values. Through experimental verification, the design scheme proposed in this article can effectively achieve power metering driven by carbon neutrality, with an accuracy of 92%.
