Design and Control of Hybrid Active Power Filters presents an overview of the current quality problems and their compensators. To get a balance between the system cost and performance, hybrid active power filters (HAPFs) are valuable. The book presents the coverage of resonance phenomena prevention capability, filtering performance and system robustness analysis of HAPF; nonlinear inverter current slope characteristics and their linear operation region requirement analysis of the hysteresis PWM for the HAPF; minimum inverter capacity design procedure of HAPF, adaptive dc-link voltage controller for the HAPF and the real design example of a 220V 10kVA HAPF, in which the system performance analysis method, minimum dc voltage deduction concept and adaptive dc voltage idea can be further extended into the other active compensators, such as APF, static synchronous compensator STATCOM, etc. This book will benefit researchers, graduate students, and electrical power engineers in the field of power-quality compensation. Dr. Chi-Seng Lam and Dr. Man-Chung Wong are both from the University of Macau, Macao, China.

This book introduces advanced thyristor-based shunt hybrid active power filters (HAPFs) for power quality improvement in power grids, which are characterized by a low dc-link operating voltage and a wide compensation range. This means they can overcome the high dc-link voltage requirement of conventional active power filters and the narrow compensation range problem of LC-coupling hybrid active power filters. Consisting of 10 chapters, the book discusses the principle, design, control and hardware implementation of thyristor-based hybrid active power filters. It covers 1) V-I characteristics, cost analysis, power loss and reliability studies of different power filters; 2) mitigation of the harmonic injection technique for thyristor-controlled parts; 3) nonlinear pulse width modulation (PWM) control; 4) parameter design methods; 5) minimum inverter capacity design; 6) adaptive dc-link voltage control; 7) unbalanced control strategy; 8) selective compensation techniques; and 9) the hardware prototype design of thyristor-based HAPFs, verified by simulation and experimental results. It enables readers to gain an understanding of the basic power electronics techniques applied in power systems as well as the advanced techniques for controlling, implementing and designing advanced thyristor-based HAPFs.

Active power filters can be used for harmonic elimination, reactive current compensation, and clean delivery of power. The basic principle of APF is to produce a compensation current which is of the same amplitude and opposite phase with harmonic currents and to eliminate unexpected harmonic currents. The shunt APF could compensate the harmonics generated by the load current through injecting compensation current to the grid. This book will have a large potential readership, ranging from scientists and students of wide disciplines to electrical engineers. It is an essential read for engineers and scientists working in the fields of power electronics and active power filters and advanced control technologies. It will also be of interest to senior undergraduate and graduate students as well as aerospace, mechanical, electrical design engineers who want to acquire some background in the advanced control of active power filters. On the science side, the book will provide important new information to control engineers, electrical engineers, and scientists. The new data and insights will enable students to have a better grasp of the complicated advanced control with application to active power filters. In short, this book will mark a milestone of an integrative approach that is needed to better understand and better manage the emerging power electronics world.

This thesis addresses the issues of filtering the harmonics in electrical grids using active power filters. Power converters are the main element of an active power filter. The performance of the filter greatly depends on the type of the converter, on the control system and on the modulation technique used to command the converter. This thesis focuses in three-level neutral point clamped converters which work as shunt active power filters to compensate the current harmonics. Firstly, this thesis makes an introduction about what is the grid quality and why is important to not have currents and voltages with significant harmonics. Secondly, we describe several converter topologies which can work as an active power filter. This description includes the well-known two-level converter and also different topologies of multilevel converters. Thirdly, we present the control system used in the studied converter. The control system includes the grid synchronization, the voltage and current loops and how we detect the current harmonics to compensate. Finally, we present some modulation techniques used in multilevel converters and the modulation used in the proposed active power filter. All the simulations included in this these have been performed using the software MATLAB SIMULINK and PLECS.

Active Power Line Conditioners: Design, Simulation and Implementation for Improving Power Quality presents a rigorous theoretical and practical approach to active power line conditioners, one of the subjects of most interest in the field of power quality. Its broad approach offers a journey that will allow power engineering professionals, researchers, and graduate students to learn more about the latest landmarks on the different APLC configurations for load active compensation. By introducing the issues and equipment needs that arise when correcting the lack of power quality in power grids, this book helps define power terms according to the IEEE Standard 1459. Detailed chapters discuss instantaneous reactive power theory and the theoretical framework that enabled the practical development of APLCs, in both its original and modified formulations, along with other proposals. Different APLCs configurations for load compensation are explored, including shunt APF, series APF, hybrid APF, and shunt combined with series APF, also known as UPQC. The book includes simulation examples carefully developed and ready for download from the book’s companion website, along with different case studies where real APLCs have been developed. Finally, the new paradigm brought by the emergence of distribution systems with dispersed generation, such as the use of small power units based on gas technology or renewable energy sources, is discussed in a chapter where mitigation technologies are addressed in a distributed environment. Combines the development of theories, control strategies, and the most widespread practical implementations of active power line conditioners, along with the most recent new approaches Details updated and practical content on periodic disturbances mitigation technologies with special emphasis on distributed generation systems Includes over 28 practical simulation examples in Matlab-Simulink which are available for download at the book’s companion website, with 4 reproducible case studies from real APLCs

Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.
