Motor reacceleration
Motor reacceleration
(OP)
I would like to know the effect of re-acceleration of motors on transient stability. What would be the effect of load transfer (induction motor loads) from one bus to another in the event of failure of supply if my motors do not have any reacceleration feature? Will natural reacceleration come into picture within the set time?





RE: Motor reacceleration
When re-closing is done after several seconds, depending on total system load, inertia and friction, the speed will drop and the starting current will be around six times the full load current until the cusp of the speed torque curve is reached again.
Sub-transient performance has been discussed before in this forum.
