Avaliação do desempenho operacional de usinas fotovoltaicas GRID-TIE a partir da utilização de softwares de simulação : estudo de caso das usinas dos campi do IFRN.

Abstract

This study aims to propose a technical analysis of the operational performance of photovoltaic power generation systems installed at the campuses of the Federal Institute of Rio Grande do Norte (IFRN). The goal is to deliver a Technical Manual for Inspection and Maintenance of Photovoltaic Systems for these plants. The basic premise is to provide a diagnosis, considering each campus's specifics, by comparing the actual annual power generation from each photovoltaic plant (using data from the monitoring systems and inverters) with simulated results using the PVsyst software. Throughout the study, we address aspects related to energy consumption evaluation from an energy efficiency perspective and detailed analysis of the design and specification of the main components, devices, and accessories used in the photovoltaic generation plants. These include photovoltaic modules, control and protection devices, electrical conductors, conduits, grounding, and various subsystems. The research is grounded in technical standards and the guidelines provided by equipment manufacturers and utility companies for grid-tie systems. The multidisciplinary nature of the study is emphasized, encompassing solar photovoltaics, energy efficiency, and low-voltage electrical installations. The methodology includes generating informative graphs from 2016 to 2022, performing simulations, and creating non-compliance reports. These will serve as a basis for developing the Technical Manual for Inspection and Maintenance of Photovoltaic Systems, ensuring maximum energy production in line with the campus descriptive reports. This study can be classified as applied research.
