Abstract
This paper will present the development and application of overhead transformers of the distribution grid, as well as the different technologies used for the gathering of electrical quantities, in the field of a monitoring solution. The solution reports the values of the quantities and alarms of operation remotely and almost in real-time. The development of this solution seeks to provide an electrical grid with greater reliability, proposing the reduction of KPIs (Key Performance Indicator), such as SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index), through more transparent monitoring of the behavior of the electrical distribution grid and its equipment. Through the research and development (R&D) project Urban Futurability, ENEL (Ente nazionale per l’energia elettrica) Distribution São Paulo seeks to apply the solution by implementing the concept of smart grids, an idea that has been growing each year by virtue of technological developments and the employment of new sensors in electrical distribution grids. Urban Futurability seeks to innovate the automation area, digital twin, and construction enhancement in the Vila Olímpia neighborhood of São Paulo, Brazil.
Highlights
The smart grids—equipped with sensors, automation, control, and new communication resources—present themselves as the step towards the modernization of the electricity distribution system, which is currently aged [1,2]
In comparison with conventional AMI equipment, the equipment described in this article seeks to monitor and report data from the distribution transformer, checking if it is operating within its temperature, voltage, and current limits, and focusing on solving specific problems of monitoring distribution transformers, which have many occurrences
This activity was conducted from February to April 2021, during which the types of defects found, the number of each defect, and the number of defects recorded in the month were collected
Summary
The smart grids—equipped with sensors, automation, control, and new communication resources—present themselves as the step towards the modernization of the electricity distribution system, which is currently aged [1,2]. With the constant increase in the demand for electricity in large urban centers, modernization in the electricity sector is necessary and adequate infrastructure is essential for both the operation and management of assets in the distribution grid [1]. According to [2,3], one of the areas of attention in terms of the utilities concerns the aged equipment installed within their concession area, which has an ever-greater chance of failing and causing an interruption in the energy supply. As a benefit of modernization, utilities will be able to reduce their operating costs, locate defects faster in the distribution grid, and decrease corrective maintenance while increasing predictive maintenance. The end consumer begins to enjoy a power grid with fewer and fewer periods of energy interruption and high reliability [1,2]
