Design and Construction of a Cubicle Control System on Medium Voltage Panels Using a Programmable Logic Controller

Abstract

Cubicle is an electrical device that functions to control, connect and protect as well as divide electricity from electric power sources. The cubicle control system is connected to a programmable logic controller (PLC) with a graphical user interface (GUI) based on Supervisory Control and Data Acquisition (SCADA) and uses the Vijeo Citect program. Com ethernet is used as data communication between PLC and SCADA. The working principle of this monitoring system is that the PLC receives commands sent by the technician via the computer, the cubicle conditions are described in graphical form in the form of a circuit to make it easier for users to operate. If the user presses the circuit to open, the PLC receives a logic command "High", then the PLC orders the cubicle to open, and vice versa, if the user presses the circuit to close, it means that the PLC receives a logic command "low", the PLC orders the cubicle to be closed. Because the command given comes from the user, a light indicator is used to ensure that the cubicle is in open/close condition. In the experiment, it was found that when the user presses the open button, the green light indicator will light up and when the close button is pressed, the red light indicator will light up and on the computer screen you will see the position of the circuit in open/close condition. The experimental results show that the cubicle control system built has been in accordance with the orders executed and the control system has been running well
