| Abstract |
The paper presents a control method of start of a
large cage induction motor. The starting process consists of two
main states. In the first state a power electronic inverter is used to
control the speed and current of accelerating motor. Therefore
the grid current is fully controlled and adjusted to references. In
the second state the power electronic inverter is off and the motor
is connected directly to grid. A method of synchronization of the
induced emf. of the motor to the grid voltage reduces transient
current and torque jerk. However, relatively long time of the
electromechanical transfer switch operation results in
displacement of the emf. and increase of the stator current. |
