- Q4/ (A) What is the voltage measurement Vx-y , for the circuit shown below. 4v 4v 20 50 yFor the system in Figure 4 with given generation and load dispatch determine the voltages after two itterations of Gauss-Seidel method. Assume the initial voltage to be 1.01 at angle of 0◦ pu at bus 1, 1.015 at angle of 0◦ pu at bus 2, and 1.0 at angle of 0◦ pu at bus 3. All line impedances are in per unit on a common base, and charging is neglected. Take base power of 100 MVA.What are the effects of making this design shorter? How does it affect the transmission lines?
