Q1[6 Marks]Interconnected Power System
a) List out the advantages of interconnected power system over isolated power system. Explain how real power and frequency balance is maintained in an interconnected power system. [6] b) With the help of suitable 3-Bus Power System Network, deduce the expression for Y-Bus Matrix elements. Also discuss how the consideration of line shunt parameter affects the Y-Bus Matrix elements.
Q2[4 Marks]Load Flow Analysis📐 Diagram in Paper
a) Consider a 3-bus power system network as shown in figure. Assume base MVA as 100 MVA. Find: [6+6]
Bus No.VoltageGenerator PQLoad QQmin RQmax R

21.020.3 p.u---10100
3-2 p.u----
(i) Voltage at bus-2 and bus-3 using G-S method (up to first iteration) (ii) Generation reactive power at bus 2 using G-S method (up to first iteration) b) Compare the performance of G-S method and N-R method for power system load flow analysis.
Q3[2 Marks]Power System Stability
(a) Derive the rotor angle swing equation and hence justify that the swing equation is a nonlinear differential equation. [6+2] (b) A 50 Hz, 500 MVA, 4-pole, 33 kV alternator has inertia constant of 7.5 MJ/MVA. Compute: (i) Stored energy at synchronous speed. (ii) The rotor acceleration in mech degree/sec if the input to the generator is suddenly raised to 400 MW for electrical load of 350 MW. (iii) The speed of rotor in rpm if the rotor acceleration is constant for 10 cycles.
Q4[6 Marks]Voltage Control and Reactive Power Management
(a) Clarify the concept of real power with frequency and reactive power with voltage in power system network. [6] (b) With a suitable example of a power system, show that the diagonal entries of a bus admittance matrix are the sum of all admittances connected to the respective buses whereas the off diagonals are negative of individual branch admittances between buses. [4] (c) Point out the key advantages of interconnected power system compared to isolated system.
