Digital control system with system of automatic control for three-phase two-zone thyristor AC voltage regulator

The digital control system of three-phase two-zone thyristor AC voltage regulator is considered and analyzed. This system has been assembled on the base of microcontroller Atmel AVR Atmega128A. The system of automatic control and protection system of current to prevent the regulator from the transition to emergency mode is proposed. The results of developing control system model are presented.
