INSTRUCTIONS TO CANDIDATES :
1.Attempt any FIVE questions out of EIGHT questions.
2.Each question carries TWELVE marks.

1. Define stability of power system. Describe the approach of small signal stability analysis
on the basis of low frequency oscillations in unregulated system.
2. Explain function of automatic voltage regulator with suitable diagram.
3. Explain large signal rotor angle stability relating dynamic equivalents and coherency.
4. Enumerate the general stability enhancing techniques in power system. How the stability
problems can be mitigated using power system stabilizer? Explain with suitable
schematic diagram.
5. Illustrate the concept of multi-machine stability in the context of conventional power
system.
6. Define voltage collapse in power system. Discuss the general characterization of voltage
collapse based on actual incidents in power system. Identify system design and operating
measures that can be taken to prevent voltage collapse.
7. What do you mean by subsynchronous oscillations in power system? Also explain
subsynchronous resonance and its counter measures. Derive the expression of
subsynchronous natural frequency for a radial series compensated system.
8. Write technical notes on :
(a) Effect of damper winding in synchronous machine.
(b) Automatic generation control.
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any
page of Answer Sheet will lead to UMC against the Student.
