2016 South Australian Blackout
The South Australian blackout of 2016 was a widespread power outage in South Australia that occurred as a result of storm damage to electricity transmission infrastructure on 28 September 2016. The cascading failure of the electricity transmission network resulted in almost the entire state losing its electricity supply, affecting 850,000 SA customers. Kangaroo Island did not lose its supply, as the Kangaroo Island power station had been built to supply the island for the contingency of a failure in the power cable under the Backstairs Passage. Storms On the day of the failure, South Australia experienced a violent storm reported as being a once-in-50-year event. There was gale force and storm force wind across wide areas of the state. It included at least two tornadoes in the vicinity of Blyth, which damaged multiple elements of critical infrastructure. The state was hit by at least 80,000 lightning strikes. The wind damaged a total of 23 pylons on electricity transmission line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Outage
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Electricity Market
The National Electricity Market (NEM) is an arrangement in Australia's electricity sector for the connection of the electricity transmission grids of the eastern and southern Australia states and territories to create a cross-state wholesale electricity market. The Australian Energy Market Commission develops and maintains the Australian National Electricity Rules (NER), which have the force of law in the states and territories participating in NEM. The Rules are enforced by the Australian Energy Regulator. The day-to-day management of NEM is performed by the Australian Energy Market Operator. NEM operations began on 13 December 1998 and currently covers Queensland, New South Wales, Australian Capital Territory, Victoria, Tasmania and South Australia. Western Australia and the Northern Territory are not connected to the NEM. The NEM comprises five regions, with the ACT being in the NSW region. Tasmania joined the NEM in May 2005 and became fully operational on 29 April 2006 when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Davenport, South Australia
__NOTOC__ Davenport is a suburb in the Australian state of South Australia located about north of the state capital of Adelaide and about north-east of the municipal seat in Port Augusta. The suburb was created on 8 July 2014 on land excluded from the existing suburbs of Port Augusta and Wami Kata. This followed a request from the Davenport Community Council, the organisation representing the aboriginal community residing there. It is located within the cadastral unit of the Hundred of Davenport. The names of private roads and the numbering of property within the suburb were approved by the council meeting of the City of Port Augusta held on 27 October 2014. Land in both the suburb and the adjoining suburb of Wami Kuta was associated with the Umeewarra Mission which was operated by the Open Brethren Assemblies of South Australia from 1937 to 1964 and whose main elements were a school and a home for children. In 1964, the mission came under the control of the South Au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mid North
The Mid North is a region of South Australia, north of the Adelaide Plains and south of the Far North and the outback. It is generally accepted to extend from Spencer Gulf east to the Barrier Highway, including the coastal plain, the southern part of the Flinders Ranges, and the northern part of the Mount Lofty Ranges. The Temperate Grassland of South Australia cover most of the area. History The main Indigenous group in the area are the Ngadjuri people. During the early colonial era, particularly in the 1850s and 1860s, disputes and conflicts occurred between settlers and the Aboriginal people. The Ngadjuri people now hold native title rights over the area. The extreme south west of the Mid North region is a part of the traditional lands of the Kaurna people. Agriculture The area was settled as early as 1840 (South Australia settlement began in 1836) and provided early farming and mining outputs for the fledgling colony.

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] |
