sinusoidal, non sinusoidal, one phase, and balanced and unbalanced three phase systems. Finally a methodology to measure power and power quality indexes based on the instant power theory under non sinusoidal conditions is proposed. Results demonstrate that using this methodology[r]
electric power will show, with a specific mitigation, such variations. Regarding the reactive power, in an asynchronous machine it is related to the active power and the applied voltage. Assuming that the voltage is almost constant, the reactive power depend[r]
