  • AC-DC Power System Analysis (Energy Engineering)

    With the expansion of HV DC transmission throughout the world, and the increasing numbers of international interconnections, few power systems can continue to escape the effect of this technology in their planning and operation. The primary subject of this book is the incorporation of AC-DC converters and DC transmission in power system analysis. However, the concepts and methods described are also applicable to the FACTS (flexible AC transmission systems) technology. As well as conventional power flows, faults and stability, the book describes the simulation of power system steady-state waveform distortion and transient behaviour. The modelling of power electronic devices in electromagnetic transient programs is given prominence, as these programs have become the 'workhorse' of power system design. This graduate-level text should be of interest to practising engineers and researchers involved in the solution of modern power system problems. It will also be a useful reference for advanced electrical engine ering students.

  • Electrical Power System Essentials

    Much of the basic hardware that generates, transmits and distributes electricity has changed little over the past century. However, the techniques applied in the power system have advanced, leading to greater transformer efficiency and more economic transmission and distribution. As the demand for electricity in both the developed and developing world increases, governments and electricity providers continue to look for alternative means of creating energy through renewable sources. Today’s needs also include well-designed systems that are capable of producing large quantities of electricity in the safest, most cost-effective way for the benefit of both individuals and industry. This book provides an accessible introduction to the interesting world of alternating current (AC) power systems, focusing on the system as a whole. After laying out the basics for a steady-state analysis of three-phase power systems, the book examines: the generation, transmission, distribution, and utilization of electric energy; the principles of thermal, nuclear and renewable energy plants; power system control and operation; the organization of electricity markets, the changes currently taking place, and the developments that could lead to alternative power systems in the future. Inside, you will...

  • Modern DC-to-DC Switchmode Power Converter Circuits (Van Nostrand Reinhold Electrical/Computer Science and Engineering Series)

    As each area of technology with a potential for significantly impacting any major segment of the electronics industry evolves, it often is accompanied by the development of a succession of new circuits. Each new circuit indeed appears different, employing different components in differing configurations, and claims an assortment of distinct features of "improved performance. " Without a considerable investment of laboratory time to construct, evaluate, and compare each candidate circuit, it usually is difficult to realistically appraise the relative merits of one approach over another. It often is even more difficult to identify the underlying principles which point up basic similarities and differences. Such is the situation in the new and rapidly expanding area known as electronic power processing or switching mode power supplies. The area of switching power supplies has been spurred by the need for power sources of higher performance, smaller volume, and lighter weight in order to achieve compatibility with the shrinking size of all forms of communication and data handling systems, and particularly with the portable battery-operated equipment in everything from horne appliances and handtools to mobile com­ munication equipment. Static dc-to-dc converters and dc-to-ac inverter...

So you can easily screw wires on it without soldering. 2) Please don't use it outdoor. It is not waterproof. Statement: Some customers complain that output power of 5V power supply is insufficient. After a series of tests, we find the reason is wrong test method, not quality issue. Because of low voltage and large current, 5V power supply requires the test wire to be thick and short enough, so as to reduce the power loss as much as possible. Compared with the 12V and 24V power supply, if the same current is to be output, 5V power supply needs a thicker output wire. For example, if the 12V 20A power supply is tested by 11 AWG test wire,no current and voltage drop, no power loss. But when we test 5V 20A power supply, in order to get sufficient 5V voltage and 20A current, 6 AWG test wire is required. If we use 11 AWG test wire or...

  • Electrical Power System Essentials

    The electrical power supply is about to change; future generation will increasingly take place in and near local neighborhoods with diminishing reliance on distant power plants. The existing grid is not adapted for this purpose as it is largely a remnant from the 20th century. Can the grid be transformed into an intelligent and flexible grid that is future proof?This revised edition of Electrical Power System Essentials contains not only an accessible, broad and up-to-date overview of alternating current (AC) power systems, but also end-of-chapter exercises in every chapter, aiding readers in their understanding of the material introduced.With an original approach the book covers the generation of electric energy from thermal power plants as from renewable energy sources and treats the incorporation of power electronic devices and FACTS. Throughout there are examples and case studies that back up the theory or techniques presented.The authors set out information on mathematical modelling and equations in appendices rather than integrated in the main text. This unique approach distinguishes it from other text books on Electrical Power Systems and makes the resource highly accessible for undergraduate students and readers without a technical background directly related to power eng...
