Authors: Maciel, Rafael Vizzotto Abstract: This thesis presents the development of a remote data reading system for power factor controllers using the Modbus RTU protocol. The objective is to monitor and optimize the power factor of electrical systems, ensuring energy efficiency and reducing costs related to reactive power penalties. The proposed solution is implemented through an architecture that involves the Siemens S7-1200 controller, equipped with the CM1241 communication module for the RS-485 interface. The power factor controller is responsible for adjusting the power factor of an electrical installation by adding or removing capacitor banks according to demand. These devices usually operate locally, which can limit the capacity for real-time monitoring and control. The S7-1200 CPU acts as the master in the Modbus communication, while the power factor controller operates as the slave, responding to requests sent by the master. The CM1241 module is responsible for establishing the connection via RS 485, a robust serial communication interface suitable for industrial environments. Through this connection, the S7-1200 performs periodic readings of operational data from the controller, such as voltage, current, power factor, and the status of the capacitor banks. These data are then processed by the controller and made available for remote visualization through the PI Vision system. The interface allows supervisors and technical teams to monitor the system’s performance in real-time, identify anomalies, and make preventive adjustments. Additionally, the system can issue automatic alerts if operational parameters exceed predefined limits, allowing for a quick and efficient response.

Authors: Souza, William Carpes de Abstract: The demand for energy has significantly increased, driven by economic growth and the rising use of electronic devices. This scenario underscores the importance of technological advancements, which are crucial for improving energy efficiency and developing alternative energy sources. Among these sources, solar energy stands out as an essential option for a more sustainable future. By adopting solar energy systems, it is possible to reduce dependence on fossil fuels and minimize environmental impacts, particularly greenhouse gas emissions. In addition to contributing to environmental preservation, solar energy offers economic benefits, such as lower electricity bills and increased property values. The large-scale adoption of this technology is a crucial step toward ensuring a cleaner, more efficient, and responsible energy matrix that meets current needs without compromising future generations. This study explores the origins and workings of solar energy, its main components, and the importance of on-grid systems, the focus of this thesis, as a viable and sustainable energy generation alternative.

Authors: Birk, Gabriel Henrique Abstract: In an increasingly digital world, with electronic equipment connected 24 hours a day in homes, the growing number of digital banking transactions and the sudden increase in robots and computers in companies, combined with the need to make institutions more technologically possible through use of robots, computers and software, the demand for electrical energy becomes increasingly necessary. Combined with increasingly unpredictable weather events, with strong periods of drought, hydroelectric plants are unable to meet the country's demand, requiring the activation of thermoelectric plants, causing a sharp rise in the price of electricity. In this context, photovoltaic systems emerge as a means of solution, to minimize costs with the use of electricity. The study takes place through the implementation of a photovoltaic system for the generation of electricity in a residence, whose main objective is to reduce the costs of a Brazilian family. A detailed analysis of the residence was carried out to dimension the system to be used, as well as the positioning and location. It should be noted that the study took place in a low voltage power generation.
