Chapter 8, Problem 8.2MCQ

In the block diagrams given rigt side, obtain the system given by number 1, as given number 2

--The negative sequence components has the ................ phase sequence with the original vectors. -The ________________ short circuit current is alternating quantity in nature. Symmetrical Unsymmetrical Offset Steady state

In series  reactive power compensation, the series capacitors are not used to increase the capabilities of transmission lines. Select one: True False

If the power system has 'n' number of generators, then the size of the B- coefficient matrix is (nxn). Select one: True False

1. what do you understood about DELTA connection? 2. What are the relationships between the Line parameters and Phase parameters in DELTA Connection?

Discuss in details and mathematical equations (and by aid of Kirchhoff’s Laws), how the obtained results may prove the validity of mesh analysis and nodal analysis.

Refer to the 5-bus data given below. Sbase = 400 MVA, the base voltage is 15.0 kV for buses 1 and 3, and 345 kV for buses 2, 4, 5. Note that 1-5 and 3-4 are 15/345 kV transformers.a) Draw a one-line diagram of the power system.b) Find the elements Y23, Y43, Y11 Y33 of the system bus admittance matrix.

The sample large power system network  data's  are  given below, The total number of buses  is 5 Three-phase short circuit fault subjected  at the bus 5  The initial voltage of the faulted bus is 1.0 p.u The Zbus matrix  element Z55 is 0.704 p.u   Fault impedance Zf= 0.33 p.u   Fault current (If )in p.u ..........
