3.3 LINE FLOWS AND LOSSESTutorial 3.2Figure 6 shows the one-line diagram of a simple three-bus power system with generation at bus 1.The voltage at bus 1 is𝑉𝑉1= 1.060°pu. The scheduled loads on buses 2 and 3 are marked on thediagram. Line impedances are marked in pu on a 100 MVA base. For the purpose of handcalculations, line resistances and line charging susceptances are neglected.a)Using Gauss-Seidel method and initial estimates of𝑉𝑉2(0)= 1.0 +𝑗𝑗0.0and𝑉𝑉3(0)= 1.0 +𝑗𝑗0.0,determine𝑉𝑉2and𝑉𝑉3. Perform two iterations. (

3.3 LINE FLOWS AND LOSSESTutorial 3.3Figure 7 shows the one-line diagram of a simple three-bus power system with generation at buses 1 and 3. The voltage at bus 1 is 𝑉𝑉1= 1.0250°pu. Voltage magnitude at bus 3 is fixed at 1.03 pu with a real power generation of 300 MW. A load consisting of 400 MW and 200 MVar is taken from bus 2. Line impedances are marked in per unit on a 100 MVA base. For the purpose of hand calculations,line resistances and line charging susceptances are neglected.a)Using Gauss-Seidel method and initial estimates of 𝑉𝑉2(0)= 1.0 +𝑗𝑗𝑗.0and 𝑉𝑉3(0)= 1.03 +𝑗𝑗𝑗.0and keeping 𝑉𝑉3= 1.03pu, determine the phasor values of 𝑉𝑉2and 𝑉𝑉3. Perform two iterations. (
