List Of HVDC Projects
Electric power transmission through interconnectors using high-voltage direct-current (HVDC) involves usually two converter stations and a transmission line. Generally overhead lines are used, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and joins two separate AC grids at a single point. Historical HVDC systems used the Thury system of motor-generators but these have all been made obsolete by later developments such as mercury-arc valves (now also obsolete), thyristors, and IGBT power transistors. Legend Converter technology: * Thury = Series-connected generators as designed by René Thury * Merc = Mercury-arc valve rectifier and inverter * Thyr = Thyristor rectifier and inverter * IGBT = Insulated gate bipolar transistor * BIGT = Bi-mode insulated gate transistor * IEGT = Injection enhanced gate transistor Line status: Africa Australia and Oceania Asia Europe 2 As of 9 December 2015, L ...

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (AC) or direct current (DC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an ''interconnection'' in North America, directly connects generators delivering AC power with the same rela ...

HVDC Inter-Island
The HVDC Inter-Island link is a long, 1200 MW high-voltage direct current (HVDC) transmission system connecting the electricity networks of the North Island and South Island of New Zealand together. It is commonly referred to as the Cook Strait cable in the media and in press releases, although the link is much longer than its Cook Strait section. The link is owned and operated by state-owned transmission company Transpower New Zealand. The HVDC link starts in the South Island at the Benmore Hydroelectric Power Station, on the Waitaki River in Canterbury and then it travels on an overhead transmission line through inland Canterbury and Marlborough to Fighting Bay in the Marlborough Sounds. From Fighting Bay, the link travels 40 km via submarine power cables underneath Cook Strait to Cape Terawhiti, Oteranga Bay, near Wellington, before travelling the final 37 km on overhead lines to Haywards transmission substation in Lower Hutt. The HVDC link first became opera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australia–ASEAN Power Link
The Australia–Asia Power Link (AAPowerLink) is a proposed electricity infrastructure project that is planned to include the List of photovoltaic power stations, world's largest solar plant, the world's largest battery, and the world's longest submarine power cable. Initial plans forecast that a new solar farm in the Northern Territory of Australia would produce up to 20 gigawatts of electricity, most of which would be exported to Singapore, and at a later point Indonesia, by a 3 GW High-voltage direct current, HVDC transmission line. A large battery would store energy in order to level energy availability as sunlight varies throughout the day. AAPowerLink has been developed by an Australian company Sun Cable, initially backed by Andrew Forrest and Mike Cannon-Brookes. It was projected to begin construction in mid-2023, with operation starting in early 2026 and completion by late 2027, and estimated to add 8 billion to the economy of the Northern Territory. The project c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Loy Yang Power Station
The Loy Yang Power Station is a brown coal-fired thermal power station located on the outskirts of the city of Traralgon, in south-eastern Victoria, Australia. It consists of two sections, known as Loy Yang A (4 units) and Loy Yang B (2 units). Both Loy Yang A and B are supplied by the Loy Yang brown coal mine. The Loy Yang power stations are located in the black coal rich Latrobe Valley, along with the Yallourn Power Station. If Loy Yang A and Loy Yang B are counted together, they are the largest power station in Australia, generating 3280 MW of power (however, if counted separately, the 2,880 MW Eraring Power Station is the largest). Loy Yang A & B are base load power stations, and together produced 23 TWh in 2024, or about 45% of Victoria's electricity requirements.

Basslink
The Basslink () electricity interconnector is a high-voltage direct current (HVDC) cable linking the electricity grids of the states of Victoria and Tasmania in Australia, crossing Bass Strait, connecting the Loy Yang Power Station, Victoria on the Australian mainland to the George Town substation in northern Tasmania. Basslink is bidirectional and enables Hydro Tasmania to supply some of the peak load capacity to the Australian mainland and take some of the excess power from the mainland when the generation on the mainland exceeds the demand. Financial benefits from the Basslink investment included reduced or deferred need to invest in further base load generation facilities, and potential to profit from selling peak load power into a market in which prices are generally higher, and because the cable was also used to supply power to Tasmania in times of drought, as most of Tasmania's electricity generation is hydroelectricity. A government review of Basslink in 2011 found, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berri, South Australia
Berri is a town in the central area of the Riverland region of South Australia. It is 238 kilometres north-east of Adelaide, the capital of the state of South Australia, and a few kilometres west of the SA-Victoria border. It is primarily an agricultural and viticultural town on the north bank of the Murray River. It is the original home of the juice company, Berri Ltd. History The name "Berri" originated from the word, “bery bery" from the local Aboriginal tribe, Meri, meaning "a wide bend in the river". The area was first explored by European settlers when Charles Sturt navigated the Murray River. Its first impetus for settlement came when paddle steamers came down the River Murray and a refuelling stop was developed. This was to become Berri. The area was also part of Cobdogla Station pastoral run before it was broken up for closer farming. In 1910, irrigation was established and Berri was proclaimed as a town in 1911. Irrigation subsequently led to the establishment of v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
