Correct option is A
· The value of slip 's' in forward regeneration mode of a three-phase induction motor drive is negative.
· When the speed of an induction motor increases faster than the speed of its stator's rotating magnetic field, the motor acts like a generator.
· This is because the slip becomes negative, which causes the torque, rotor current, and power to also become negative.
· The motor then starts supplying power or current to the supply lines, which is how it behaves as an induction generator.
