Question details

armonics and Active Power Calculation: Example Background to the example: Harmonic loads are prevalent in many modern distribution systems. They include almost all DC-powered equipment or appliances such as computers, chargers for our electronic gadgets, televisions etc While one such unit may give negligible effects to the supply grid, a collection of these units (such as those at a University or commercial offices) can lead to a substantial degradation to current and (to a certain extent) voltage waveforms. The waveforms on the left are described by 100 r(t) i(t) 100 sin at + 20 sin 5at 10 sin(ot - 15°) +2 sin(5ut-75°) -100 0.03 0.04 001 Time() 0.01 0.02 a) Write down the expression of p() in 3 20 terms of ot b) Determine the active power from the expression ofp(t)ina) 004 001 0.02 001 Time () a03 Write down your solutions here:
