Abstract :
Questions of the development of a speed-controlled sensorless electric drive based on the thyristor slip recovery system for a wound-rotor motor in case of a higher rotor voltage in comparison with a matching transformer voltage are considered in this paper. The algorithm uses the data of measured currents and voltages of rotor and grid-tie inverter. Results of computational modeling of the suggested system and its implementation have been presented.
