description: The topic of the final qualifying work: "Methods of calculation and modeling of measuring circuits of wattmeters and energy meters". This work is devoted to the study of measuring circuits of wattmeters and energy meters, in particular, an inexpensive Analog Devices electricity meter on the AD7755 chip was studied, on the basis of which a simplified scheme of a real energy meter was developed. Tasks that were solved in the course of this work: 1. Analysis of conversion methods for measuring electrical energy and power. 2. Modeling of precise power converters operating in a wide range of input voltage, current, and power changes. The work was carried out on the basis of the "Multisim" software package, where a significant part of the actual material was collected: Instantaneous voltage at the output of the voltage channel, instantaneous voltage at the output of the multiplier, active load power. Calculations were carried out, showing clearly how the resistance and load capacity affect the measurement error. As a result, the influence of resistive and capacitive loads was analyzed, calculations of errors were carried out. Effective load values have been developed at which the measurement error is minimal. Based on the materials of the conducted research, it is possible to compile methodological manuals for laboratory work on methods and devices for measuring power and energy.
