Power system analysis Q1) Short answer questions:1. For a solid single line to ground fault the sequence networks areconnected:In parallelIn a star configurationIn seriesJust the positive and negative networks are connected since thereis no fault impedance.2. (True, False) A balanced three phase fault is the most common type oftransmission line fault.A.B.C.D.3. For which fault types will there be a zero sequence current that is non-zero:A. 3 phase, L-L, SLG, DLGB. L-L, SLG, DLGC. 3 phase, L-L4. Give two reasons why the slack bus is needed for the power flow problem:5. (True, False) Pre fault operating conditions influence the magnitude of thefault current.6. (True, False) During a fault at a specific bus in a system, the voltage isdepressed at all busses in the system.7. In a power flow study, what are the state variables?8. In a power flow study, what does a flat start mean?9. (True, False) The Gauss sidle power flow method is based on Taylor seriesexpansion.10. (True, False) All the elements in an impedance matrix representing a powertransmission system are positive.

Faults in the power system refer to abnormal conditions which lead to disruption in the flow of…
