Essay: Discuss how voltage regulation / power delivery is achieved in high voltage AC power networks. Include a comparison between different types of method to include advantages / disadvantages of FACTS devices versus more traditional approaches.
Title: Power Control in HVAC
Part 1 Traditional methods of control of voltage / power delivery in networks
Part 2 FACTS
Part 3 Examples of FACTS in operation new plants or HVAC schemes involving FACTS
Figure 1 shows the one-line diagram of a simple three-bus power system with generation at bus 1. The voltage at bus 1 is V1 = 1.0∠0° per unit.
i. Compute the per unit voltages at buses 2 and 3 again using the Gauss-Seidel method (assume for the purpose of this computation that SB = 100 MVA + your birthday (i.e. birth day 20 of the month
SB = 100 +20 = 120 MVA))
My birthday is 19
ii. Verify the results of your computation via the use of a proprietary Gauss Seidel programme (you must cite source of your program).
iii. (10 marks)
Z12 = 0.5 Ω Bus 2 = 300 MW + 200 Mvar
Z13 = 0.125 Ω Bus 3 = 350 MW + 250 Mvar
Z23 = 0.75 Ω
