An Intelligent Automation of Power Transformer using PLC and SCADA at Substation

Abstract

In this paper, SCADA, and PLC (programmable logic controller) are used in the substation to automate the control of transformers. The substation is where the power for the generator and the primary supply comes from the generating station to the distributor or the end user via the transmission line. Each substation has its own set of activities, such as switching transmission lines, measuring parameters, detecting faults, and storing historical data. All these tasks were performed by one person, as the system becomes more advanced it moves to automation. Monitoring, controlling, and acquiring of data can be performed by SCADA and a PLC (Programmable Logic Controller) in an automated substation. In the case of a low voltage, a transformer set at the substation is quickly turned on by the power management system using SCADA. A PLC, or "programmed logic controller," regulates the voltage in a substation. Substation automation has three categories, First RTU data is sent to controllers for system monitoring or management. The second PLC generates control commands based on system parameters, and the third SCADA allows for human-machine interaction.
