Implementação de métodos padronizados de cálculo de grandezas elétricas para aplicação em hardware-in-the-loop

Abstract

This work is an integral part of a research macroproject resulting from the collaboration between the Federal University of Santa Maria (UFSM) and Typhoon. The central focus of this macroproject is the design of a testing platform for the pre-certification of photovoltaic inverters, using the Hardware-in-the-Loop (HIL) technique. The specific contribution of this work to the macroproject involves the implementation and validation of measurement algorithms in compliance with international standards, in addition to assessing the reliability of their measurements through an uncertainty analysis. Throughout this process, specific objectives were established, starting with a review of the main international standards related to the measurement of electrical quantities. Subsequently, a validation methodology for the measurement algorithms was developed, followed by an analysis of sources of uncertainties, including a numerical estimation of these sources. These algorithms played a crucial role in ensuring that the measurements made during the testing phase accurately reproduced what would be done by a commercial energy analyzer during the certification process. Thus, the scope of this work focused on the implementation, validation, and uncertainty analysis of these algorithms, all based on international standards. The results obtained during the validation of the measurement algorithms and the uncertainty analysis demonstrated their suitability for the purposes of this work, effectively fulfilling the proposed objectives. These results strengthen the foundation of the research macroproject, emphasizing the importance of these algorithms in ensuring the reliability of measurements at all stages of the development of the photovoltaic inverter, from initial tests to project completion.
