Presents Fundamentals of Modeling, Analysis, and Control of Electric Power Converters for Power System Applications Electronic (static) power conversion has gained widespread acceptance in power systems applications; electronic power converters are increasingly employed for power conversion and conditioning, compensation, and active filtering. This book presents the fundamentals for analysis and control of a specific class of high-power electronic converters—the three-phase voltage-sourced converter (VSC). Voltage-Sourced Converters in Power Systems provides a necessary and unprecedented link between the principles of operation and the applications of voltage-sourced converters. The book: Describes various functions that the VSC can perform in electric power systems Covers a wide range of applications of the VSC in electric power systems—including wind power conversion systems Adopts a systematic approach to the modeling and control design problems Illustrates the control design procedures and expected performance based on a comprehensive set of examples and digital computer time-domain simulation studies This comprehensive text presents effective techniques for mathematical modeling and control design, and helps readers understand the procedures and analysis steps. Detailed simulation case studies are included to highlight the salient points and verify the designs. Voltage-Sourced Converters in Power Systems is an ideal reference for senior undergraduate and graduate students in power engineering programs, practicing engineers who deal with grid integration and operation of distributed energy resource units, design engineers, and researchers in the area of electric power generation, transmission, distribution, and utilization.

Steven Blume W. High Voltage Protection for Telecommunications

Sets forth the steps needed to protect critical telecommunications circuits from power faults and lightning in high voltage environments The need to protect telecommunications circuits from power faults and lightning has never been greater: when power outages or system disturbances occur, reliable telecommunications are essential. With this book as their guide, readers will know what they need to do (and not do) to protect critical telecommunications circuits and equipment located in high voltage environments such as electrical power plants, substations, and power towers. Moreover, the book explains how to get the job done safely, detailing the proper implementation of safety procedures and the use of protective equipment to eliminate or minimize risk. Setting the foundation, the book begins with an overview of the problem, key issues, industry standards, and safety concerns. Next, it covers: Definitions and fundamentals of electric power systems, with regard to HVPT applications Causes, boundary conditions, and calculations of ground potential rise Critical telecommunications circuits that must be protected in high voltage environments Protection schemes and equipment to resolve ground potential rise problems Effective installation and testing of high voltage interface equipment Personal safety for telecommunications personnel working with equipment in high voltage environments Throughout the book, the author refers to accepted industry standards and best practices. Written by one of the most respected professional trainers in the telecommunications industry, High Voltage Protection for Telecommunications can be used for professional training courses or self-study. It will enable readers to protect critical data and voice communications circuits from high voltage events and protect themselves during equipment installation and maintenance.
