[Abstract]:Nowadays, with the development of smart grid technology, more strict standards have been put forward for energy measurement. In addition, the accuracy of energy measurement is closely related to the economic interests of users, power plants and power supply bureaus, and more accurate and fair measurement is particularly important. At present, there are few researches on the influencing factors of digital gate watt-hour meter. Therefore, the research on the factors influencing the measurement performance of digital gate watt-hour meter has a strong practical significance to improve the accuracy of electric energy measurement. The main research work of this paper is as follows: (1) the structure of digital electric energy metering system and the error source of digital electric energy metering system are studied, and the structure and principle of digital gate watt-hour meter are analyzed. The factors affecting the metering performance of digital gate watt-hour meter are analyzed. (2) the relative error caused by data loss, spectrum leakage, fencing effect and finite word length effect, harmonics and different electric energy integration algorithms are studied. (3) the measurement model of three-phase watt-hour meter is constructed on Simulink platform, and the relative error caused by AD quantization, trapezoidal integral, harmonics and the interaction of the three factors are verified and analyzed by the metrological model. The results show that the larger the sampling frequency of AD, the smaller the relative error caused by the influencing factors, the smaller the relative error caused by the power factor, the smaller the relative error caused by the influencing factors. (4) using the power source, the standard analogue table. Voltage conversion device, current conversion device, data acquisition device, digital standard source, digital gate meter, error analysis device and upper computer, a set of digital power metering instrument traceability system is built. Under the condition of different power factor and load current, the output electric pulse of standard meter and the light pulse of gate electric energy meter are simulated, and the test data are obtained. Under the guidance of "Evaluation and representation of Measurement uncertainty", the uncertainty of digital gate watt-hour meter is evaluated.
