Answer Posted / a.kannan,

Asnchronous Generator is nothing but a Induction motor
operating in a negative slip region .ie Whenever the
induction motor rotates greater than its synchronous speed
(by coupling external source)then the power will return
towards (negative torque)the network which its is
connected.WIND MILLS are worked on this prinsiple.It is
clear that in the wind mill there is a induction motor.It
has great advadage that we need not to sychronise the wind
mill when it is connected to the system.

Starting times for soft starter & power factor is thier any standard or datas available in manufactures list. Kindly suggest.
