Note: Draw the schematic and code for each of the following question. All question carries equal marks.

1. Design heat control system as follow.

Design a system to maintain the temperature of the system at 37 degree celcius.A temperature sensor is attached with the Arduino analog input. A fan (220 volts) and heater (220V) is placed in a room. If temperature is greater than 37 degree, turn the fan on and if temperature is less than 37 turn on heater.

Take the temperature reading after every 10 minutes.

*Hint: Use relay to turn on Fan and heater.Control the realy using Arduino.

One main feeder have two sub feeders (Sub Feeder-A and Sub Feeder-B). If the Sub Feeder-A has demand at a time to be 35 kW and Sub Feeder-B has demand at a time as 42 kW, calculate the total individual maximum demand (MD), the demand of the whole system and the diversity factor if the maximum demand of the main feeder is recorded as 70 kW. Explain the possibility of having the main feeder’s MD to be equal with the sum of both sub feeder’s MD.

In a circuit we have a source with 75 W impedance that we want to connect to a 300 W load with a transmission line with characteristic impedance of 75 W. To achieve maximum power transfer an inductor will be connected in series to the source.

a. Use the Smith Chart on the next page to get the minimum length of the line in wavelengths and the inductor reactance value. Write down the values here.

b. Use the input impedance formula, Zin, for a lossless line to get the value of the input impedance with the length given by the Smith Chart.

c. Compare the reactance of the Smith Chart and the formula.

Please provide a digital design circuit modeled in
**structural verilog** that takes two 5-bit inputs (in
2's complement format), and a add/subtract input. If add/subtract =
0 than the circuits ouputs A+B, If add subtract = 1, the circuit
outputs A-B (by taking the 2's compliment of B and than
adding).

A 400 V,50 Hz, six-pole three-phase induction motor drives a
constant load of 140 N.m. The motor has the following
parameters

?1=0.294 Ω

?1=1.39 ??

??=41 ??

?2′=0.156 Ω

?2′=0.74 ??

1) Starting.

Calculate the following:

i) Motor starting current.

ii) Motor starting torque.

2) Maximum operating point. Calculate the following:

i) Slip at which maximum torque is developed.

ii) Maximum torque developed.

3) Steady-state operation.

Calculate the following:

i) Motor slip.

ii) Motor speed.

iii) Motor current.

iv) Motor power factor.

v) Motor input power.

vi) Motor output power.

vii) Motor efficiency.

4) Speed control of the induction motor:

We need to control the speed of the load by controlling the speed
of the induction motor using the ?/? method. The load should be
driven at 700 rpm at the same slip obtained in part 3-i
above. Calculate the following:

i) The source line-line voltage and frequency.

ii) Motor current.

iii) Motor power factor.

iv) Motor input power.

v) Motor output power.

vi) Motor efficiency.

vii) The line voltage control method can not be used here to reduce the motor speed to 700 rpm, Why? Fully explain your answer.

Notes:

- For calculation:

▪ Use the recommended IEEE equivalent circuit.

▪ Use five decimal digits.

▪ Make sure all equations and numbers are clear.
