“…In the series APF with shunt PF, the active filter is connected across the series to provide high impedance and isolation path for the harmonics to follow in the shunt PF. This configuration is commonly tested in medium-voltage level systems to provide reactive power, voltage harmonic compensation, and three-phase voltage balancing [106]. …”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.

In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may cause the neutral point potential on the grid side to shift. The neutral point potential shift will worsen the control precision as well as the performance of the threephase four-wire unified power quality conditioner (UPQC), and it also leads to unbalanced three-phase output voltage, even causing damage to electric equipment. To deal with unbalanced loads, this paper proposes a matching-ratio compensation algorithm (MCA) for the fundamental active component of load currents, and by employing this MCA, balanced three-phase grid currents can be realized under 100% unbalanced loads. The steady-state fluctuation and the transient drop of the DC bus voltage can also be restrained. This paper establishes the mathematical model of the UPQC, analyzes the mechanism of the DC bus voltage fluctuations, and elaborates the interaction between unbalanced grid currents and DC bus voltage fluctuations; two control strategies of UPQC under three-phase stationary coordinate based on the MCA are given, and finally, the feasibility and effectiveness of the proposed control strategy are verified by experiment results.

“…Scholars introduce design and implementation of series hybrid APF in these papers [36][37][38][39][40][41]. The series hybrid APF is capable of compensating current as well as voltage harmonics [36]. The combination can improve filter performance and provide a cost-effective topology in harmonic compensation.…”

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
