Compensação de potência reativa com utilização de banco de capacitores em um sistema elétrico industrial

Abstract

When analyzing any type of electrical power system, there are several variables that we must discuss, such as: voltage levels (whether there is overvoltage or undervoltage), electrical current that passes through the conductors, stability, operating conditions, generation, protection, among many other aspects of the electrical grid. With this in mind, the motivation for this work is to assist in the analysis of industrial electrical systems, which are those with the smallest variety of studies and tools developed for this area. This study contains a solid theoretical basis on capacitors, which begins with the basic principles and their characteristics and even includes specific applications of the capacitor bank, such as industrial applications and their installation in some types of load. Furthermore, we use the methodology for calculating power flow using pandapower, a tool that uses a Berkeley Software Distribution (BSD) license and can be easily compiled in Google Colab. The document covers the structuring of the network, and the basic structuring of the code and even the creation of a simple industrial electrical network. It then explains how to install the pandapower libraries and create the elements. The network is then demonstrated without the use of the shunt element and then with the capacitors. Finally, all the results collected from each of the simulations are shown, which allows us to conclude the real influences of the installation of the capacitor bank on the voltage levels and to reliably deduce findings about active power and reactive power.
