Some parameters are given related to your student ID numbers. These are: V1 = XXX V (first 3 numbers, e.g. 170 V (RMS)) f1 = XXX Hz (assume that your last number is ‘y’, then f1 = (y+1)*10 Hz, e.g. if y=2 then f1=(2+1)*10=30Hz) 1) A single-phase load has an active power of P = 2 kW at V1 V @f1Hz and the power factor is cosφ = 0.75. This motor is compensated to cosφ = 0.85 using a parallel capacitor (the load is modelled as series RL). Determine: a. Reactive power and apparent power before compensation using power factor b. Current before compensation c. R, XL and L values of the load

1) A single-phase load has an active power of P = 2 kW at V1 V @f1Hz and the power factor is cosφ = 0.75. This motor is
compensated to cosφ = 0.85 using a parallel capacitor (the load is modelled as series RL). Determine:
a. Reactive power and apparent power before compensation using power factor
b. Current before compensation
c. R, XL and L values of the load
d. Reactive power and apparent power after compensation
e. Find the reactive power difference between compensated and uncompensated status (which will give the
capacitor power) and calculate XC and C using the power difference value
f. Simulate the uncompensated and compensated circuits. Plot voltage and current on components and
calculate the phase shift of the signals from Vin
g. Plot Vin and Iin comparison for both circuits and show/calculate the phase angles for circuits.
