Zusammenfassung der Kapitel (Chapter Summaries)

The introduction highlights the growing concern of power quality issues due to the increased usage of non-linear loads and electronically switched devices in distribution systems. The paper proposes a novel control method based on the SRF for a three-phase UPQC to mitigate these problems.

Chapter II provides a detailed overview of the UPQC, describing its configuration, components, and functionalities. It emphasizes the ability of the series and shunt converters to address various power quality concerns.

Chapter III delves into the SRF technique, explaining how it can effectively extract harmonics from supply voltages or currents for compensation purposes. The chapter highlights the transformation of three-phase signals into stationary and synchronous frames.

Chapter IV elaborates on the proposed UPQC control algorithm. It explains the computation of reference switching signals for both the series and shunt active filters, based on the SRF approach. The chapter outlines the generation of reference voltage signals for the series active filter, emphasizing the importance of compensation for voltage distribution problems. It further describes the reference current signal generation for the shunt active filter, focusing on the mitigation of current harmonics and reactive power.

Chapter V presents simulation results obtained using MATLAB-SIMULINK, demonstrating the effectiveness of the proposed control strategy in mitigating the impact of unbalanced and non-linear load conditions. The chapter highlights the ability of the system to achieve unity power factor and effectively isolate loads from voltage sags.
