Design and Implementation of a Multi-Source Automatic Transfer Switch (ATS) System to Run the Utility Systems Via Different Power Sources and 3-Phase Synchronous Industrial Generator

Abstract

An automatic transfer switch (ATS) is a device that automatically shifts a power source from its primary source to a backup source when the primary source fails or breaks down. When a primary power system fails, the ATS activates a standby power source, such as an uninterruptible power supply. An ATS can also start longer-term backup power systems, such as Industrial diesel or gas-powered generators, to keep power sources running until utility power comes back. Because of the poor power supply in developing countries, alternative power generation with automation is required to support utility supply. Automation has grown in popularity and now plays a vital role in the electronic industry. Electromechanical relays, magnetic contactors, and delay timers are the main components of designing an ATS, which has three input power and one output power source. To avoid loss of life or data, both of which are very expensive in business operations, delicate processes, and activities in hospitals, the pharmaceutical industry, and many other essential businesses require continuous power support. Therefore, a system that can operate autonomously with little or no human involvement is designed and implemented for a three-phase synchronous industrial generator that will power the utility systems. This project’s most exciting feature is its ability to automatically activate the secondary power source once the primary one fails due to a power breakout because it has multiple source inputs and a single output. When both sources fail because of a breakout, it turns on the industrial Generator and turns it off when either the primary or secondary power source is again restored.
