3. Consider the impedance diagram of Figure Q3 in which the system parameters are given in per unit by Z11 = Z22=j0.25, Z12=j0.2, Z13=j0.25, Z23 = Z34j0.4 and Z24 = j0.5 Develop the nodal admittance matrix for each of the network branches and then write the nodal admittance equation of the systems. Evaluate the note voltage for each of the notes. -Ea+ Z11 Z13 V₁ (000) 10002 (000) ZA (000) (000) Z22 Z24 V -Eaz Figure Q3 Impedance diagram of the power network.
