Taking advantage of the harmonics at the load side using passive filters

Utilization of harmonics current in single phase system

“…5) Losses Reduction Method: The authors in [13] propose to add a third harmonic to the PWM reference signal to alter the harmonic spectrum of sinusoidal PWM inverters and thus reduce motor losses. 6) Reuse the harmonic current in three phase system: The authors in [14] [15] presented a new idea to reuse the harmonics via proposing a new topology of three phase passive filter [14] and a new topology of three phase hybrid active power filter (HAPF) [15]. However, these topologies are still complex in design as represent three phase system.…”

Electrical distribution grid of Kirkuk City: A case study of load flow and short circuit valuation using ETAP

“…However, the use of FACTS technology and the creation of distributed generators have made the distribution system, and hence the DSLF procedures, substantially more complicated than prior versions, have rendered the distribution system, and hence the DSLF procedures, significantly more sophisticated than previous versions. Thus, Through an exhaustive bibliographic study, the growth of today's three phase unbalanced DSLF with numerous feeding sources, embedded FACTS devices, advanced software techniques, and so on has been documented in this work [6,7]. The authors of [8] proposed Newton Raphson on three-phase system for power-flow due to its robust convergence.…”
