Available in PDF, EPUB and Kindle. Book excerpt: Flexible AC Transmission Systems (FACTS): Newton Power-Flow Modeling of Voltage-Sourced Converter-Based Controllers introduces different voltage-sourced converter (VSC)-based FACTS controllers and VSC-based high-voltage direct current (VSC-HVDC) systems and their working principles, explaining how FACTS controllers exchange real and reactive power with systems. Subsequently, the book: Describes the Newton–Raphson method and its application for solving the power-flow problem Presents the Newton power-flow modeling of the static synchronous series compensator (SSSC), unified power-flow controller (UPFC), interline power-flow controller (IPFC), generalized unified power-flow controller (GUPFC), and static synchronous compensator (STATCOM), accommodating the practical device constraint limits (because of the unique modeling strategy, the existing Newton power-flow codes can be reused) Develops a unified Newton power-flow model of AC systems incorporating multiterminal VSC-HVDC systems with pulse-width modulation (PWM) control schemes, directly yielding the VSC modulation indices from the power-flow solution Provides numerous case studies for validation of Newton power-flow models, elaborating on the occurrences and checking of unrealistic power-flow solutions in isolated cases Includes detailed derivations of all the difficult formulae as well as solved problems on typical VSC-based FACTS controllers Flexible AC Transmission Systems (FACTS): Newton Power-Flow Modeling of Voltage-Sourced Converter-Based Controllers assumes at least an undergraduate-level understanding of engineering mathematics, network analysis, electrical machines, electrical power systems, and power electronics. Thus, the book provides a valuable reference for practitioners as well as senior-undergraduate and graduate students in electrical engineering and electrical power systems.

Available in PDF, EPUB and Kindle. Book excerpt: Our ever-increasing dependence on electricity demands improvements in the quality of its supply. The deregulation of electric (and other) utilities, the events of 9/11, and the blackouts in North America, London, and the Italian peninsula evidence this need. This book looks at our current transmission systems and how loop circuits can substantially improve the reliability of transmission lines, essentially to provide a two-way feed to the consumer and insuring continuity of service if a fault develops on the circuit. It also covers distribution systems and includes information on how small generating units can be connected directly to the distribution system in the same manner as in larger cogenerating units.

Download or read book Low Frequency Ac Transmission for Power Systems written by Tuan Anh Ngo and published by . This book was released on 2017 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional transmission systems utilize either high voltage ac (HVAC), operating at 50 or 60 Hz, or high voltage dc (HVDC) to transfer bulk power. The HVAC system is designed to operate at a high voltage level to reduce losses and increase bulk power transfer. This method is limited, however, by the constraints of installed transmission overhead lines, such as voltage level and power transfer capability. In contrast, the HVDC system can handle a large amount of power on the transmission line by utilizing dc current instead of ac. While the HVDC system has no limitation in transmission line length for power transfer, it does however, require a high initial cost for converter stations and specialized protection systems. Additionally, the HVDC system is a point-to-point connection, and thus not flexible for multi-terminal connection. The low frequency ac (LFAC) transmission system, first introduced in 2000, is another solution for bulk power transmission that inherits advantages from both high voltage ac and high voltage dc systems. The primary advantage of LFAC transmission is that by operating the system at a frequency lower than 50 or 60 Hz, the transmission line reactance can be significantly reduced, thus extending power capacity. Further advantages include multi-terminal connections, distance protection using alternating-current based circuit breakers, and improving power transfer capability close to that of an HVDC system. This dissertation investigates the benefits of an LFAC system in terms of power transfer capability and voltage stability. First, the steady-state performances of the transmission line under low frequency range are investigated, including the skin effect to see any possible changes in transmission line model. More importantly, the power transfer capability, and voltage profiles during no-load and full-load conditions are examined. Next, the system voltage stability under low frequency operations is studied in detail to analyze how the low frequency operation helps improve a power system stability. Furthermore, the system modeling, protection, and hardware platform to test the low frequency ac transmission are studied deeply. A new grid synchronization configuration to interface a low frequency system with a 60 Hz ac system is also proposed. Moreover, a fast and robust fault detection mechanism based on the second-order generalized-integrator (SOGI) grid synchronization technique is to develop and work properly in a low frequency system. Last but not least, a small-scaled transmission and distribution system is built to verify the basic performances of a power system at a low frequency operations

Download or read book Power Transmission by Direct Current written by E. Uhlmann and published by Springer. This book was released on 1975-10 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The direct current transmission scheme linking the island of Gotland to the main land of Sweden by means of a submarine cable under the Baltic Sea is the first commercial realisation of a modern technique for the transmission of electrical energy. It is certainly not accidental that this pioneering initiative was allotted to the Gotland scheme. Various viewpoints may be presented regarding this, but the essential factor relates to the circumstances that permitted the magnitude ofthe transmitted power to be given a value which would not have been technically or economically feasible for any other project. The power, on the one hand, was sufficiently small to justify the risk associated with such a new venture, for it fell within limits acceptable both to ASEA as the manufacturer and to the Swedish State Power Board as the customer. On the other hand, the power was large enough to demonstrate the technical and economic characteristics of the new system and to provide the opportunity of gaining invaluable experience that could be applied to future large-scale transmission systems. In 1954 a team under the direction of Dr. Uno Lamm successfully commissioned the Gotland scheme, representing the culmination of many years of intensive development work.

This book was released on 1995 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis examines how Flexible AC Transmission Systems (FACTS) devices can improve the secure-economic operation of a power system. More specifically, the benefits of FACTS devices in a network are evaluated in terms of four areas of power system study: system security, economic dispatch operation, maximum network loadability and electric industry deregulation. Simulations of a simple network are made to evaluate how a FACTS device can be used to increase the security region of a network. Based on this analysis, simulations are performed using the 24-bus IEEE reliability test network to assess the possible savings in generation costs, the increase in maximum network loadability and the improvements in flexibility of exchanges resulting from the use of a FACTS device in this network. The results demonstrate that FACTS devices can be used effectively to increase the security region of a network thereby allowing for a better optimum operating point in any optimization problem performed over such a region." --
