What is the reactive power and how to control the reactive
power in power plant

Answer Posted / prabhat kumar sinha, banswara.

The Power taken by pure reactance in a circuit is called
reactive Power. The Unit of reactive power is VAR.
Reactive Power = Apparent power x value of Sin angle of
between voltage & current = VI Sin phi.
It can controled by the increase the angle of Sin, it means
close to Sin phi = Sin 90° = 1.

We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
