Ask question #Minimum 10] In the system shown in Figure 4-1, the rated voltage of the line is 110kv, and the conductors are all LGJ-120 type. The parameters are: r1=0.21O/km,x1=0.4O/km, b1=2.85*10-6S/km, and the line lengths are: l1=150km, l2=100km, l3=75km. The transformer capacity is 63000kVA, the rated voltage is 110 / 38.5kv, the short-circuit voltage percentage is Uk%=10.5, and it operates on the -2.5%. The rated capacity of the capacitor is 5MVA. If SB=100MVA and UB=UN is chosen, try to form the node admittance matrix of the system.0 words accepted#
