Abstract:

This paper presents a didactic procedure and the specific equipment, dedicated for training students or specialists in the field of low voltage power quality. Today electronic equipment includes a large number of devices having very fast and frequent load variations, used due to some obvious benefits like energy efficiency, flexibility, low volume, low costs and even increased reliability. Despite all advantages, these devices are also producing some important power disturbances on electrical distribution lines, mostly harmonics or fast changes and fluctuations of the reactive power. All power quality related aspects become mandatory today, for all electrical, power and electronical engineers worldwide. By consequent, permanent training and formation of all specialists acting in this area, according to the updated norms and regulations of this field, becomes a real necessity nowadays. Our training module procedure is related to a main component of power energy quality in electrical power systems: harmonics/interharmonics pollution of a current wave passing throughout a normal nonlinear domestic load/consumer. First, we present some generalities about harmonics, followed by the presentation of a very simple and efficient method for power quality assessment, which was materialized in a dedicated educational, scientific and didactic platform. All experimental results obtained are confirming the theoretical models applied for making this educational platform. Finally, there is a set of specific conclusions, related to all experiments performed and there are also specifications for future perspectives of using this didactic equipment.
