Development of an automated control system for 6/0.4 kV transformer substation with automatic transfer switch using standard IEC 61131-3

This work is devoted to the development of an automated transfer switch (ATS) for 6/0.4 kV substation. The relevant due introduction automation and replacement electromechanical equipment with microprocessor devices in power systems. At lower (field) level, driven by use programmable logic controllers (PLCs) various smart sensors. possibility using modular PLC systems considered. Developed are algorithm a program implementation regulation application automatic switches at substation recommendations IEC 61131.3 “Programming languages controllers” standard.
