Automação da modelagem de dispositivos eletrônicos inteligentes (IEDS) SEL no engineering base PTD: fundamentos técnicos e proposta de padronização This Final Course Project is situated within the context of the Fourth Industrial Revolution and the digitalization of power system projects, focusing on the Engineering Base PTD (EB) platform developed by AUCOTEC—a data-centric tool that integrates all phases of the lifecycle of transmission and distribution plants. Digital protection relays, classified as Intelligent Electronic Devices (IEDs), are critical components in Safety, Protection, Control, and Supervision (SPCS) projects. Currently, the modeling of these devices from the manufacturer Schweitzer Engineering Laboratories (SEL) in Engineering Base is performed manually, resulting in lack of standardization among created models, extended execution time, and increased risk of errors. The general objective of this work was to develop an application (macro) in Engineering Base PTD capable of automatically modeling SEL protection relays based on the input of the device's part number, thereby promoting agility, reliability, and standardization. To achieve this objective, the following specific goals were pursued: understanding the state of the art in digital protection relays; mapping the technical data available on SEL's official website; cataloging all protection relay models offered by the manufacturer; recording the part number variations corresponding to different input and output configurations; and developing the macro for automated modeling in the Engineering Base environment. Finally, a comparative analysis was conducted between the traditional manual process and the proposed automated process, evaluating parameters such as modeling time, reduction of manual errors, and the level of standardization achieved. The results demonstrate that the developed solution reduces the modeling time, commonly around 1 hour, to around 23 seconds, eliminates inconsistencies between projects, and minimizes human error, contributing to greater efficiency, traceability, and quality in SPCS projects carried out on the Engineering Base PTD platform

Análise dos indicadores de qualidade de energia elétrica no IFPE Campus Garanhuns In this paper, an analysis is presented of the electric power quality at IFPE Garanhuns Campus, which has a specific load profile related to its academic purpose and, in parallel, a photovoltaic plant installed in its internal grid. To carry out the study, field measurements were taken that gathered data on load, voltage, power, harmonics, generation, power factor, and frequency. Analysis of these data enabled an assessment of power quality on the campus, the identification of limit violations with respect to current standards, and a detailed description of the operation of the electrical installations, including the photovoltaic plant. For the data analysis, Module 8 of the Procedures for the Distribution of Electric Energy (PRODIST) in the National Electric System, published by the National Electric Energy Agency (ANEEL), which addresses the quality of energy supply in distribution systems, was taken as a reference. The indicators of long-duration voltage variation, power factor, harmonic distortions, voltage imbalance, and frequency variation were analyzed. The data analysis revealed the presence of violations of the campus’s power-quality standards, including voltage variations, low power factor, and harmonic distortions. Therefore, the study demonstrated the importance of evaluating power quality in installations with distributed generation, as is the case at IFPE Garanhuns. The outcomes can serve as groundwork for implementing measures aimed at enhancing the campus electrical system, ensuring the quality of electric power supply. Furthermore, the study contributes to the advancement of knowledge in the field of power quality, especially in the context of educational institutions with distributed generation

Curtailment e armazenamento da energia: efeitos no fluxo de potência em região de alta geração renovável e carga atípica The Brazilian electricity grid is primarily comprised of renewable energy sources such as solar and wind. However, the inclusion of these sources presents new challenges for electricity sector players. While wind and solar power grew exponentially, the system's transmission lines and load capacity did not grow at the same pace. As a result, curtailment measures have become increasingly common to ensure generation load balance. These challenges highlight the need to introduce new technologies to help overcome these limitations. Thus, Energy Storage Systems (ESS) present an effective solution, as they can store and inject energy at desirable times. In this context, this paper sought to present a case study of the implications of incorporating these technologies into an electricity grid inspired by the Brazilian Electric System (SEB), focusing on the Ourolândia 230 kV substation located in the state of Bahia. In the methodological context, the requirements of the Grid Procedures, storage system modeling, and simulation strategies were developed using ANAREDE. The main results indicate that, for all baseline simulation scenarios, some system buses violated voltage limits, requiring the insertion of voltage control elements. Regarding the insertion of energy storage systems, no operational limits were violated. Furthermore, their application in the heavy-load scenario contributed significantly in the supporting at the local load.

Contribuições à manutenção elétrica na usina solar fotovoltaica do IFPE - Campus Garanhuns The main objective of this final undergraduate project was the development and implementation of an electrical maintenance plan for the photovoltaic power plant of IFPE – Garanhuns Campus, aimed at improving the system’s energy performance and promoting practical actions of inspection, cleaning, and operational monitoring. From the analysis of the plant’s current operation, several issues were identified, such as the absence of real-time monitoring, inoperative inverters, soiling of the modules, and the lack of regular maintenance practices. To address these, irradiance measurements with a pyranometer, electrical tests, and comparisons between the projected generation (with PR = 0.80) and the actual measured generation were performed. The cleaning of two strings resulted in a 1.63% efficiency increase, which, when projected for the entire plant, represents a potential gain. As a practical contribution, a maintenance plan was developed, including periodicity tables, inspection forms, and operational recommendations, along with the proposal to reuse available inverters from the laboratory and involve students in the maintenance process, thus integrating the initiative into the educational context. The results demonstrate that the adoption of systematic maintenance practices can significantly increase the plant’s generation levels and reduce electricity costs for the campus.
