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 iscompensated 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 factorb. Current before compensationc. R, XL and L values of the loadd. Reactive power and apparent power after compensatione. Find the reactive power difference between compensated and uncompensated status (which will give thecapacitor power) and calculate XC and C using the power difference valuef. Simulate the uncompensated and compensated circuits. Plot voltage and current on components andcalculate the phase shift of the signals from Ving. Plot Vin and Iin comparison for…
