RT Journal Article T1 Optimum System for Diagnosing Power Quality in Electrical Microgrids A1 Gómez Ruiz, Gabriel A1 Sánchez Herrera, María Reyes A1 Delgado Martín, Aránzazu A1 Andújar Márquez, José Manuel A1 Gómez Ruiz, Gabriel AB An electrical measurement network designed for analyzing power quality within microgridsis presented in this paper. It is very portable and easy to install across various types of microgrids.Data collected by the system meet the standards for measuring electrical parameters, calculatingwaveforms spectra and comparing results from different microgrid nodes. The measurementsprovided by the network are useful for both utility and consumer sides. The system’s effectiveness isverified through two experimental setups, specifically built ad hoc: one for testing the accuracy of themeasurements obtained and the other for assessing the suitability of these measurements for powerquality analysis.
