This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct current (dc) power systems are gaining more attention in academia and industry due to their advantages compared with conventional alternating current (AC) power networks. DC systems present higher efficiency at the same voltage levels, they need no frequency synchronization and reactive power compensation, and they ease the integration of renewable energies. Despite the advantages of dc power systems, there are still several technical and practical challenges that slow down their widespread adoption and development worldwide. One of the primary technical challenges that must be addressed is the development of dc circuit breakers (DCCBs).Among DCCBs, dc solid-state circuit breakers (SSCBs) use semiconductor devices to conduct load currents during the normal operation and hold dc bus voltages during the breaker OFF-state. Among many benefits, SSCBs present an ultrafast response speed, a modular structure, no arc problems, extended operation cycles, and a high compactness, fulfilling the urgent needs of emerging technologies such as electric ships. However, solid-state switches used in SSCBs have limited voltage/current turn-off capability and thermal capacity, requiring more investigations in the field. This thesis focuses on advanced techniques to enhance lifetime, safety, and reliability in dc SSCBs. There are four main contributions as follows. Firstly, soft turn-off dc SSCBs are introduced, where compact and fast active injection circuits (AIC) are used to eliminate the transient energy and mitigate gate voltage oscillations in solid-state switches during current interruption, extending the SSCBs lifetime. Second, active snubbers in dc SSCBs are discussed, and novel topologies are presented to extend the maximum allowable dc bus voltage on SSCBs, remove the voltage on passive components during the SSCBs OFF-state, and solve the reliability issue of varistors in SSCBs. Next, fault current bypass-based dc SSCBs are proposed, where fault currents are reduced to zero at the load side or faulty sections within microseconds regardless of the dc system's line inductance, improving safety. Finally, SSCBs are studied at the system-level, and a new protective scheme is developed to optimally coordinate dc ultrafast SSCBs in multi-source dc microgrids. In summary, dc SSCBs play a key role in newly established dc power systems. SSCBs present a fast response speed, a modular structure, and high compactness. In this thesis, advanced techniques are introduced to improve lifetime, safety, and reliability in dc SSCBs at device- and system-level.

Available in PDF, EPUB and Kindle. Book excerpt: The lack of effective DC fault protection technology remains a major barrier for the DC paradigm shift. In addressing the key challenges, Direct Current Fault Protection: Basic Concepts and Technology Advances starts with an introduction to the advantages of DC power systems before moving on to an in-depth review of DC fault protection technologies, including mechanical circuit breaker (MCB), solid-state circuit breaker (SSCB), hybrid circuit breaker (HCB), converter based (breakerless) protection, and fault current limiter (FCL). Coverage includes a comprehensive comparison of various DC fault interruption technologies and their suitable applications, state-of-the-art DC fault protection concepts and advances in research, identification of fundamental challenges and future directions in the field, and commercialization aspects. This book will be a valuable reference for practicing engineers, researchers, and graduate students in the field of power electronics and DC power systems.

Book excerpt: DC MICROGRIDS Written and edited by a team of well-known and respected experts in the field, this new volume on DC microgrids presents the state-of-the-art developments and challenges in the field of microgrids for sustainability and scalability for engineers, researchers, academicians, industry professionals, consultants, and designers. The electric grid is on the threshold of a paradigm shift. In the past few years, the picture of the grid has changed dramatically due to the introduction of renewable energy sources, advancements in power electronics, digitalization, and other factors. All these megatrends are pointing toward a new electrical system based on Direct Current (DC). DC power systems have inherent advantages of no harmonics, no reactive power, high efficiency, over the conventional AC power systems. Hence, DC power systems have become an emerging and promising alternative in various emerging applications, which include distributed energy sources like wind, solar and Energy Storage System (ESS), distribution networks, smart buildings, remote telecom systems, and transport electrification like electric vehicles (EVs). All these applications are designed at different voltages to meet their specific requirements individually because of the lack of standardization. Thus, the factors influencing the DC voltages and system operation needed to be surveyed and analyzed, which include voltage standards, architecture for existing and emerging applications, topologies and control strategies of power electronic interfaces, fault diagnosis and design of the protection system, optimal economical operation, and system reliability.

Available in PDF, EPUB and Kindle. Book excerpt: The design and development of two direct current (DC) solid-state circuit breakers (SSCBs) for use in low voltage DC distribution systems were examined. Both SSCBs utilized the isolated-gate bipolar transistor (IGBT) and were developed for low current applications of under 20 A. The approach was documented to show the advancement of IGBT technology and the fundamental understanding of high-side drive topologies and their applications. A 500 V 20 A SSCB was designed to accommodate specifications provided by Portland Architects and Engineers (PAE). The design featured two optocoupler gate drives to operate four non punch through (NPT) IGBTs in parallel, and a thermal experimentation led to the calculated temperature rise at full load operation to be 9.79 °C above ambient temperature. The SSCB’s response to over current events of 120 A and 180 A was simulated to show a maximum voltage of 883 V and 1.21 kV respectively. The second SSCB developed was designed and experimentally tested to operate at 50 V with up to 10 A of continuous current using free air conditions. Experimental response and trip times for pickup (PU), total clearing time (TCT), and switching time (SWT) were found to average 43.74 μs, 47.53 μs, and 3.79 μs respectively. The average response time was found to be roughly 290 times faster than that of a conventional mechanical circuit breakers (MCBs) operation and exemplifies how the SSCB can be used to fill the gaps in conventional alternating current (AC) protection systems. The DC distribution system is capable of extreme faults that could damage sensitive power electronic equipment, and the DC distribution system and the SSCB are a continuing point of research that has the potential to drive the power industry to higher efficiencies and better utilization of clean energy systems.

Book excerpt: This book offers a comprehensive reference guide to the important topics of fault analysis and protection system design for DC grids, at various voltage levels and for a range of applications. It bridges a much-needed research gap to enable wide-scale implementation of energy-efficient DC grids. Following an introduction, DC grid architecture is presented, covering the devices, operation and control methods. In turn, analytical methods for DC fault analysis are presented for different types of faults, followed by separate chapters on various DC fault identification methods, using time, frequency and time-frequency domain analyses of the DC current and voltage signals. The unit and non-unit protection strategies are discussed in detail, while a dedicated chapter addresses DC fault isolation devices. Step-by-step guidelines are provided for building hardware-based experimental test setups, as well as methods for validating the various algorithms. The book also features several application-driven case studies.
