sequence impedances are given by
Z1=j0.1599
Z2=j0.1599
Z0=j1.7120
Fault Current= -j1.3422
Components currents flowing from Generator and motor are
Ig1= -j0.1363
Ig2= -j0.1363
Ig0=0
Im1= -j0.3111
Im2= -j0.3111
Im0= -j0.4474
Fault current from the generator towards g are
- 0.2725981i
0.1362990i
0.1362990i
and to g from motors are
- 1.0696512i
- 0.1362990i
- 0.1362990i
Positive sequence current =-0.136 pu
Negative sequence current =0.136 pu
Zero sequence current=0
The per unit motor currents are:
Motor1:0.66 +j0.495 pu
Motor2:0.33 +j0.247 pu
Voltage behind subtransient reactances:
Motor1:Em1= 1.0798-j0.2278
Motor2:Em2= 1.0798-j0.2278
Generator:Eg= 0.5193j+0.5199
The actual value of positive sequence current from the generator towards fault is = 0.99+j0.606
The actual value of positive sequence current from the motors towards fault is = -0.99-j1.054
