Cahora Bassa Dam
The Cahora Bassa Dam is located in Mozambique. It is one of two major dams on the Zambezi river, the other being the Kariba. The dam was finished in December 1974 after much political debate. This dam is used to convert the Zambezi River power into electricity by turning turbines. That energy is then sent to South African cities, farms, and mines. The Cahora Bassa dam forms Cahora Bassa Lake. The dam is jointly owned by Mozambique and Portugal. From independence till 2007, eighteen percent of the dam and lake was owned by Mozambique and eighty-two percent by Portugal. Portugal sold down its share to 15 percent in 2007. The Cahora Bassa dam is the largest hydroelectric power plant in southern Africa and the most efficient power generating station in Mozambique. History The dam began to fill in December 1974 after construction was commenced in 1969 by the Portuguese colonial government of Mozambique (Portugal), and is high by wide at the crest.

Zambezi River
The Zambezi River (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers , slightly less than half of the Nile's. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. The Zambezi's most noted feature is Victoria Falls. Its other falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls near Sioma in western Zambia. The two main sources of hydroelectric power on the river are the Kariba Dam, which provides power to Zambia and Zimbabwe, and the Cahora Bassa Dam in Mozambique, which provides power to Mozambique and South Africa. Additionally, two smaller power stations are along the Zambezi Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accumulator (energy)
An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed. Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval. Some accumulators accept energy at a high rate over a short time interval and deliver the energy at a low rate over longer time interval. Some accumulators typically accept and release energy at comparable rates. Various devices can store thermal energy, mechanical energy, and electrical energy. Energy is usually accepted and delivered in the same form. Some devices store a different form of energy than what they receive and deliver performing energy conversion on the way in and on the way out. Examples of accumulators include steam accumulators, mainsprings, flywheel energy storage, hydraulic accumulators, rechargeable batteries, capacitors, inductors, compensated pulsed alternators (compulsators), and ...

List Of Conventional Hydroelectric Power Stations
This article lists hydroelectric power stations that generate power using the conventional dammed method. This list includes power stations that are larger than in maximum net capacity, and are operational or under construction. Those power stations that are smaller than , or those that are only at a planning/proposal stage may be found in regional lists, listed at the end of the page. The largest hydroelectric power station is the Three Gorges Dam in China, rated at in total installed capacity. After passing on 7 December 2007 the mark of the Itaipu Dam, the facility was ranked as the largest power-generating facility ever built. The dam is high, long and in width. Power is generated by 32 turbines rated at , and two turbines rated , which are used to power the facility itself. Construction of this dam commenced in 1994, and was completed in 2012, nearly two decades after it started. The next six largest dams after the Three Gorges Dam are the Itaipu Dam, Xiluodu Dam, Bel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cahora Bassa (HVDC)
Cahora-Bassa (previously spelled Cabora Bassa) is an HVDC power transmission system between the Cahora Bassa Hydroelectric Generation Station at the Cahora Bassa Dam in Mozambique, and Johannesburg, South Africa. History The system was built between 1974 and 1979 and can transmit 1920 megawatts at a voltage level of 533 kilovolts DC and 1800 Amperes.Compendium of HVDC schemes, CIGRÉbr>Technical Brochure No. 003 1987, pp89–94. Thyristor valves are used, which unlike most other HVDC schemes are mounted outdoors and not in a valve hall. The valves are grouped into eight, 133 kV six-pulse bridges in series at each end. The long powerline runs through inaccessible terrain, so it is mostly built as monopolar lines apart. In case of a single line failure, transmission with reduced power is possible via the surviving pole and return through the earth. Cahora-Bassa was out of service from 1985 to 1997 because of the Mozambican Civil War in the region. The p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
