Projeto e simulação de um quadro de transferência automática.

Abstract

Load Transfer Switches (LTS) are devices that switch between power supply of a load according to pre-established criteria, whether they are variations in the supply of that load or other factors such as consumption and even surplus reactive. Therefore, it is necessary to create a circuit in order to measure such quantities, monitor them and, at the right time, switch between these power sources. They are widely used in systems that operate with negative pressure, soil irrigation, milking and other activities considered complex. Load Transfer Switches can also be used in large industries, homes and buildings, as well as in energy generators used in businesses and events. In this work it was proposed the design and simulation of an Automatic Transfer Switch (ATS) that performs the switching process between electrical sources whenever the power factor falls below a limit value. For this,the Proteus software was used to design the simulation and the graphical interface was made using textit NI LabVIEW software. With the simulation it was possible to study the electronic instrumentation used in a QTA, as well as its behavior.
