Al-Fadhili Back To Back HVDC Converter Station
The Al-Fadhili back-to-back HVDC station is a back-to-back HVDC connection between Saudi Arabia, whose grid operates at 60 Hz, and its neighbouring Gulf states which have 50 Hz grids.Barrett,B.T., MacLeod,N.M, Sud,S., Al-Mohiasen, A.I., Al-Nasser,R.S.Planning and design of the Al Fadhili 1800 MW HVDC inter-connector in Saudi Arabia, CIGRÉ session, Paris, 2008, paper reference B4-113. The station is located in Saudi Arabia, approximately 100 km north-west of Dammam, but was built for and owned by Gulf Cooperation Council Interconnection Authority (GCCIA). The converter station was built by Areva T&D, now Alstom Grid, between 2006 and 2009. GCCIA is constructing a 400 kV, 50 Hz AC transmission line to interconnect Kuwait, Bahrain and Qatar through Saudi Arabia. Later phases will also connect Oman and United Arab Emirates. The Al-Fadhili HVDC system allows power to be exchanged between the 50 Hz GCCIA system and Saudi Electricity Company system. The ...

Qatar
Qatar (, ; ar, قطر, Qaṭar ; local vernacular pronunciation: ), officially the State of Qatar,) is a country in Western Asia. It occupies the Qatar Peninsula on the northeastern coast of the Arabian Peninsula in the Middle East; it shares its sole land border with Saudi Arabia to the south, with the rest of its territory surrounded by the Persian Gulf. The Gulf of Bahrain, an inlet of the Persian Gulf, separates Qatar from nearby Bahrain. The capital is Doha, home to over 80% of the country's inhabitants, and the land area is mostly made up of flat, low-lying desert. Qatar has been ruled as a hereditary monarchy by the House of Thani since Mohammed bin Thani signed a treaty with the British in 1868 that recognised its separate status. Following Ottoman rule, Qatar became a British protectorate in 1916, and gained independence in 1971. The current emir is Tamim bin Hamad Al Thani, who holds nearly all executive and legislative authority under the Constitut ...

HVDC Converter
An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies.Arrillaga, Jos; High Voltage Direct Current Transmission, second edition, Institution of Electrical Engineers, , 1998, Chapter 1, pp 1-9. HVDC converters capable of converting up to two gigawatts (GW)Davidson, C.C., Preedy, R.M., Cao, J., Zhou, C., Fu, J., Ultra-High-Power Thyristor Valves for HVDC in Developing Countries, IET 9th International Conference on AC/DC Power Transmission, London, October 2010. and with voltage ratings of up to 900 kilovolts (kV)Skog, J.E., van Asten, H., Worzyk, T., Andersrød, T., Norned – World’s longest power cable, CIGRÉ session, Paris, 2010paper reference B1-106. have been built, and even higher ratings are technically feasible.

High-voltage Direct Current
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
