It is certainly not accidental that this pioneering initiative was allotted to the Gotland scheme. High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems.

For example, it allows more efficient bulk power transfer over long.

It is certainly not accidental that this pioneering initiative was allotted to the Gotland by: transmission systems were also direct current systems. However, DC power at low voltage could not be transmitted over long distances, thus giving rise to high voltage alternating current (AC) electrical systems.

Nevertheless, with the development of high voltage valves, it was possible to once again transmit DC power at high voltages and over File Size: KB.

About the Author DRAGAN JOVCIC, P H D, is director of Aberdeen HVDC Research Centre and a Professor with the University of Aberdeen, Scotland, by: Major milestones in the development of high voltage direct current (HVDC) technologies and concepts were achieved in s.

Thanks to the high power thyristor switches (s), the HVDC. Electrical Power System by JB Gupta is very useful for basics ideas of power system and best for competitive exams And topics are covered in sufficient book for power system courses.

Book Name – A Course In Power Systems By JB Gupta Author – J B Gupta. Starting in the late s, Thomas Edison and Nikola Tesla were embroiled in a battle now known as the War of the Currents. Edison developed direct current -- current that runs continually in a single direction, like in a battery or a fuel cell.

During the early years of electricity, direct current (shorthanded as DC) was the standard in the U.S. High Voltage Direct Current, HVDC power transmission, which is characterized with low energy loss and lower capital cost for transmission over long distances.

For over years High Voltage Alternating Current, HVAC has been considered as the natural choice for electrical power transmission. 1 Why High Voltage Direct Current. Highlights from the High Voltage Direct Current (HVDC) History The transmission and distribution of electrical energy started with direct current.

Ina km-long 2-kV DC transmission line was built between Miesbach and Munich in Germany.

At that time, conversion between reasonable consumer voltages andFile Size: 3MB. Direct current (DC) is the unidirectional flow of an electric electrochemical cell is a prime example of DC power.

Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion electric current flows in a constant direction, distinguishing it from alternating current (AC).

10 DC versus AC transmission + Show details-Hide details p. – (25) High-voltage transmission serves a dual purpose, i.e. system interconnection and bulk-energy transfer.

With reference to system interconnection, the need to operate the whole system in perfect synchronism often prevents the transfer of power by alternating current: the economic power ratings of such interconnections Cited by: K.R.

A substation is a high-voltage electric system facility. It is used to switch generators, equipment, and circuits or lines in and out of a system.

It is also used to change AC voltages from one level to another, and/or change alternating current to direct current or direct current to alternating current.

Power transmission is usually performed with overhead lines as this is the most economical way to do so. Underground transmission by high-voltage cables is chosen in crowded urban areas and in high-voltage direct-current (HVDC) submarine connections.

Power might also be transmitted by changing electromagnetic fields or by radio waves; microwave energy may be carried efficiently over short. Try the following books not only for transmission and distribution but for all other topics in Power system: 1.

Power system Engineering -by Kothari & Nagrath 2. Electrical Power — C.L. Wadhwa If you are interested only in transmission and distrib. Electric power transmission is the transmitting of electricity to places where it will be used.

Specifically, it is the bulk transfer of electrical power from the power plant to substations near populated areas. Electric power distribution is the delivery from the substation to the consumers. Due to the large amount of power and long distances, transmission normally takes place at high voltage.

Since the distance that electric energy can be transmitted by alternating current transmission is limited for various reasons, direct current transmission is used for long distance transmission. There are advantages and disadvantages in using high voltage direct current transmission.

Power quality is a major concern in electric networks. This book is one of a series of EPRI Power Delivery color book series. The HVDC book will be published with a distinct “olive” color cover.

The Olive book will build on the existing two EPRI HVDC Reference Books – HVDC Transmission Line Reference Book (TR) and High Voltage Direct Current Handbook (TR).File Size: 76KB. Since the first edition of this book inHVDC technology has continued to develop and few power systems can now escape its influence.

Fully revised, updated and expanded, this second edition builds on its predecessor's coverage of HVDC systems and describes the variety of reasons justifying the use of DC transmission as well as the basic concepts and techniques involved in the AC-DC and 4/5(1).Direct current is a bit easier to understand than alternating current.

Rather than oscillating back and forth, DC provides a constant voltage or current. DC can be generated in a number of ways: An AC generator equipped with a device called a "commutator" can produce direct current.

Use of a device called a "rectifier" that converts AC to DC.High Voltage Direct Current Transmission. The purpose of this section is to provide an introduction to the two fundamental modes in which electric energy is transmitted—alternating current (AC) and direct current (DC)—and to compare the ability of these two options to address the challenges of enhancing the resiliency of modern power Size: KB.
