“…3 shows a series APF, which is connected in series with the load and the utility through a matching transformer. Series APF applications are described in literatures [28][29][30][31][32][33][34][35]. Unlike shunt APF, a series-connected APF acts as a voltage source and is used for AC voltage regulation and suitable for large capacity diode rectifiers with capacitive loads [1].…”

This thesis presents a demonstration of Real-Time High-Speed controller hardware-in-the-loop (CHIL) testing for a digital signal processor (DSP) -based controller of a shunt active power filter (APF) for medium voltage (MV) grid power quality improvements. A recently developed Real-Time and high-speed simulator (RT Box) and a DSP are used for the CHIL simulation to validate the control algorithms which are implemented in a commercial low-cost DSP. The filter reference current is extracted based on synchronous reference frame theory. Hysteresis current control is employed to generate PWM switching signals for controlling the APF to inject compensating currents into the grid. The direct current (DC) side capacitor voltage level of the APF is maintained by a PI controller. The results show the APF associated with the implemented controller can mitigate variety power quality problems, such as harmonic elimination, power factor correction, and load balancing. The whole CHIL simulation system work stable with high switching frequency.ii

“…The shunt active power filter, SHAPF, is usually used to mitigate load problems such as source current harmonics due to non-linear and the unbalanced load, power factor improvement, reactive power compensation, and voltage instability on the load side [17][18][19][20][21][22]. The series active power filter, SEAPF, is usually used to mitigate grid or mains problems, such as voltage sags, voltage swells, voltage dips, voltage unbalances, voltage interruptions, voltage phase shift, and voltage harmonics [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. The unified power quality conditioner, UPQC, is utilized to solve all of the previous problems; this is called a universal active power filter and consists of a combination of shunt and series active power filters [38,39].…”

Power quality improvement faces different and significant problems due to voltage instability and the wide use of electronic power devices. To overcome these different power quality problems, an active power filter is used. The active power filter, in general, has 4 main categories- shunt, series, unified power quality conditioner, and hybrid active power filter. The shunt active power filter is usually used to mitigate source current harmonics and compensate reactive power for power factor correction. The series active power filter is usually used to mitigate voltage problems (sags, swells, transients, dips, distortions, harmonics, etc.). The unified power quality conditioner is a combination of the shunt active power filter and the series active power filter; it is used to mitigate all voltage and current problems, compensate voltage, current system harmonics, and reactive power compensation, and mitigate voltage dips, voltage sags, voltage swells, and voltage phase shift. In this paper, the 3-phase 3-wire unified power quality conditioner is utilized to mitigate all power system problems (voltages and currents) and discuss the effect of the shunt and series active power filter separately on source voltage and source current waveforms. This case study shows that the source voltage distortion can be mitigated by using the series active power filter alone, but the source current distortion cannot be mitigated without using both the series and shunt active power filter. The source current harmonic problem mainly exists due to 1) distorted voltage sources, and 2) non-linear loads. Therefore, the unified power quality conditioner must be used to mitigate source current distortions in the case of the distorted voltage source, to comply with the standard limits IEEE 519, IEC 555, and IEC 61000. HIGHLIGHTS The UPQC is used to mitigate all voltage and current problems and improve all power system quality The SEAPF eliminates all voltage problems The SHAPF has no effect on source voltage The SHAPF eliminates source current harmonic distortion GRAPHICAL ABSTRACT

The power quality improvement faces different significant problems due to the wide use of power electronics and voltage instability. To overcome these different power quality problems, an active power filter is used. The active power filter in general has four main categories, shunt, series, unified power quality conditioner and hybrid active power filter. The shunt active power filter is usually used to mitigate source current harmonics and compensate reactive power for power factor improvement. The series active power filter is usually used to mitigate voltage problems (sags, swells, transients, dips, distortions….). The unified power quality conditioner is used for all voltage and current problems. In this paper, the three phase three-wire series active power filter is utilized alone to mitigate all power system problems (voltages and currents) for this case study, such as voltage sag, voltage swell, voltage harmonics, and source current harmonics to comply with the harmonics limits given in IEEE 519-1992, and IEC 61000-4-7 standards. The source current harmonic problem mainly exists due to, 1) distorted voltage source, and 2) non-linear loads. The series active power filter can effectively eliminate the source current harmonics in case of distorted voltage source. Consequently, the series active power filter can be used alone as a power quality improvement for all voltage and current problems as mentioned in this case study.
