Table 1

Calculate the following for the car park using the data from Table 1:

a) the maximum real power demand P (kW)

b) maximum reactive power demand Q (kVAr)

c) the total apparent power demand S (kVA)

d) also, calculate the maximum current magnitude |I| if the supply voltage magnitude |V| is 3.3 kV and the supply frequency is 50 Hz.

e) Calculate the overall car park power factor.

f) Calculate the rating of the capacitor bank (μF) needed to improve the car park power factor to unity.

g) Calculate the new maximum current magnitude, after power factor correction. Again assume the supply voltage magnitude is 3.3kV and frequency is 50 Hz.

h) Select the cable ID from Table 2 that you would use to supply the car park BEFORE AND AFTER power factor correction has been applied.

i) Comment on your result.

Table 2

Design a clocked synchronous state machine with two inputs, A and B, and a single output Z that is 1 if
(1) A had the “different” value at each of the two previous clock ticks, or
(2) B has been 1 since the last time that the first condition was true.
Otherwise, the output should be 0.
Design state assignment using decomposed method. D Use flip-flops to a minimum, and design the next-state logic with a minimal 2-level NAND-NAND circuit. Do not consider multiple-output minimization when designing next-state logic.
