“…The specifications of three phase inverter are indicated in Table 2. Inverter module consists of IGBT switches SKM75GB123D (3 No's), diode bridge rectifier PSD8316, IGBT Gate Drivers SKYPER 32 R and DC Link Capacitors 4700µF (2 No's). The controller in SAPF calculates the reference currents for hysteresis controller that will be injected into power system by three phase IGBT inverter.…”

Power quality is the most significant factor of power sector. The end user equipment such as induction motor, inverters, rectifiers inject harmonics into power system that influences the quality of power delivered. The presence of harmonics forces the use of instantaneous reactive power theory to calculate instantaneous power that helps in finding the compensating currents to eliminate harmonics. The control action required by active filter is accomplished by STM32F303RET6 microcontroller. Single phase induction motor is used as a dynamic nonlinear load in one of the three phases and resistive loads on the other two phases. TRIAC based RC triggering circuit was used to control the single phase induction motor. This paper presents the simulation and hardware implementation of shunt active power filter for 3 phase 4 wire unbalanced system. The hardware results show that THD in the source side has been reduced from 50.7% to 9.6% by implementing the SAPF.

“…The nature of energy conveyed to the end client is influenced by different factors such as voltage and frequency variations, faults, blackouts and so forth. These power quality issues reduce the life time and productivity of the electrical equipment [1][2][3][4]. A large portion of the loads are likewise semiconductor based.…”

“…Los problemas más comunes de calidad de energía son la caída de tensión, los armónicos y los transitorios de conmutación. En su mayoría, estos son causados por la naturaleza intermitente de las generaciones de energía no convencionales, transitorios debido a la conmutación de capacitores y grandes alimentadores de carga (Anzalchi et al 2019;Kavitha and Subramanian 2017).…”

The smart grid concept is being applied more and more frequently and this is due to the need to integrate all the components that are part of power systems today, starting from generation units, storage systems, communications and connected loads. Non-linear and non-stationary signals have been obtained in this type of systems, which have high penetration of non-conventional energy sources (NCSRE) and non-linear loads. The power quality criterion has had to be adapted to the new conditions of the electrical systems and this has led to the need to search for new analysis methodologies for the acquired signals. In this article we present a review on non-linear and non-stationary signal analysis methods in electrical systems with high NCSRE penetration. To this end we explore the application of the Hilbert-Huang Transform (HHT), Wavelet Transform (WT) and Wigner-Ville Distribution (WVD), exposing each of the advantages and disadvantages of these methods. To validate the methodology, we have selected some synthetic signals that adequately describe the typical behaviors in these systems.

“…Harmonic filters are used to reduce the effect of their harmonics, which cause serious damage to energy system elements. Energy quality problems have negative effects on the energy distribution system and consumers [1]. Energy quality problems cause energy losses in energy systems, decreased device life, noisy operation of devices, incorrect measurement of sensitive devices, damage of compensation systems, overload of transformers, decrease in insulation life, failures in relay protection and automation processes [2]- [7].…”

In this study energy quality of university campus network have been analyzed experimentally. The experimental tests and measurements have been implemented at Engineering Building of the Bolu Abant Izzet Baysal University (Turkey). Energy quality analysis has been performed by making current, voltage, frequency, power factor, harmonics, neutral-earth voltage measurements at the main distribution board of the Engineering Building. Besides, active power filter has been connected and its effects examined. The reasons for the energy quality problems on the electric power distribution system of the campus building have been revealed and required solutions have been offered.
