Create a 3-bit counter in verilog that cycles through this sequence, 6,2,4,5,0,7,3,1, with a synchronous rest 4.

(i) Design an 8-bit ripple adder which can add together two 8-bit numbers, inside a hierarchical block. Explain your design. Name your block with your student number: eg “123456 ripple adder”. (ii) Test your circuit in block form, showing four example additions with manual calculations to show they are correct. [

1. In a power system with negligible resistance, the three-phase fault current at a point is 8 pu. The series reactance to be inserted at the fault point to limit the short circuit current to 5 pu

2. A 3-phase, 15 MVA, 10 kV alternator has internal reactance of 6% and negligible resistance. Find the external reactance per phase to be connected in series with the alternator so that steady current on short circuit does not exceed 6 times the full load current.

3. A 3-phase, 13.8 kV, 50 MVA alternator has positive, negative and zero sequence of 0.20, 0.20 and 0.05 pu. If the alternator is on no-load, determine the fault current for a three-phase fault.

Derive the equations (for average value of load voltage) of three phase half controlled rectifier and three phase full controlled rectifier ?

: A dc motor develops 55 N-m torque at a speed of 600 rad/s when 12 volts are applied. It stalls out at this voltage with 100 N- m of torque. If the inertia and damping of the armature are 7 kg-m2 and 3 N-m -s/rad, respectively, find the transfer function, G(s) = θL(s)/Ea(s), of this motor if it drives an inertia load of 105 kg-m2 through a gear train, as shown in the figure 11.

6. A 30 MVA generator with 15% reactance is connected to a bus bar. A 25 MVA transformer with 10% reactance is also connected through a 10% bus bar reactor to the same bus bar. Both of these reactance is based on 25 MVA. If a feeder taken out from the bus bars through a circuit breaker develops a three-phase fault, what should be the appropriate rating of the circuit breaker?

7. A system operates at 220 kVA and 11 kV. Using these quantities as base values, find the base impedance for the system.

8. Three 6.6 kV, 12 MVA, 3-phase alternators are connected to a common bus bars. Each has reactance to positive sequence current of 15%. The reactance to negative and zero sequence current are 75% and 30% of the positive sequence value. If an earth fault occurs on one of bus bar, determine the fault current when one of the alternator neutral is earthed through a resistance of 0.25 ohm and the others are isolated.

9. Four identical alternators each rated for 20 MVA, 11 kV have a subtransient reactance of 16% are working in parallel. The short circuit level at the bus bar is.

10. A generator having a solidly grounded neutral and arte 50-MVA, 30 kV has positive, negative and zero sequence reactances of 25, 15 and 5 percent respectively. What reactance must be placed in the generator neutral to limit the fault current for a line to ground fault to that for a three phase fault?
