The frequency variable drivers of induction motors are typically used to control mechanical load. In the paper a frequency control method is proposed to affect regime of the grid that feeds these motors. The method provides successful self-starting or restarting after significant power disturbance of group induction motors.
The proposed strategies are applicable for smart grid, for example, demand response technology works well for industrial loads. It is can be useful not only for normal regimes but in case of emergency, for instance, dynamic demand provides accurate control of the load. Both technologies (demand response or dynamic demand) are well integrated in smart grid concept.
