Mount Emerald Wind Farm
Mount Emerald Wind Farm is a 180 MW wind farm situated on Mount Emerald, in Arriga, Shire of Mareeba, Queensland, Australia. It is approximately 8 km WNW of Tolga, and 49 km SW of Cairns. The project is a joint venture between Port Bajool (land owner) and RATCH-Australia (wind farm developer and operator). RATCH-Australia bought the project from Transfield Services in July 2011. Construction The site was formerly used as a military training area in World War II so the site had to be carefully inspected to find any unexpoded ordnance; several were found and safely destroyed. Operations The wind farm registered its first grid output in August 2018 and reached maximum output in January 2019. The electricty network around the wind farm is generally constrained; this has an impact on the total amount of electricity it can receive from the wind farm. Studies are being undertaken to increasing the capacity of the network using technologies such as synchronous cond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Farms In Queensland
Wind is the natural movement of atmosphere of Earth, air or other gases relative to a planetary surface, planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption (electromagnetic radiation), absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their scale (spatial), spatial scale, their speed and direction, the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind Power In Australia
Wind power is one of the main renewable energy sources in Australia contributing 10% of Australia's total electricity supply in 2020, and making up 37.5% of it's renewable energy supply. Wind resource testing conditions in Australia are optimum, as abundant wind resources may be located close to residential areas in the southern parts of the country and on the slopes of the Great Dividing Range in the east. As of the end of 2020, there was 7,376 megawatts (MW) of installed wind power capacity contributing 9.9% of generation to the electricity sector in Australia, and a further 4,021 MW of capacity was committed or under construction. Wind resources Australia has excellent wind resources by world standards. The southern coastline lies in the roaring forties and many sites have average wind speeds above 8 or even 9 m/s at turbine hub height. The southwest portion of Western Australia, south of South Australia, western Victoria, the north of Tasmania as well as elevated areas ...

Battery Storage Power Station
A battery storage power station is a type of energy storage power station that uses a group of batteries to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition from standby to full power within milliseconds to deal with grid failures. At full rated power, battery storage power stations are generally designed to output for up to a few hours. Battery storage can be used for short-term peak power and ancillary services, such as providing operating reserve and frequency control to minimize the chance of power outages. They are often installed at, or close to, other active or disused power stations and may share the same grid connection to reduce costs. Since battery storage plants require no deliveries of fuel, are compact compared to generating stations and have no chimneys or large cooling systems, they can be rapidly installed and placed if n ...

Synchronous Condenser
In electrical engineering, a synchronous condenser (sometimes called a syncon, synchronous capacitor or synchronous compensator) is a DC-excited synchronous motor, whose shaft is not connected to anything but spins freely.B. M. Weedy, Electric Power Systems Second Edition, John Wiley and Sons, London, 1972, page 149 Its purpose is not to convert electric power to mechanical power or vice versa, but to adjust conditions on the electric power transmission grid. Its field is controlled by a voltage regulator to either generate or absorb reactive power as needed to adjust the grid's voltage, or to improve power factor. The condenser’s installation and operation are identical to large electric motors and generators (some generators are actually designed to be able to operate as synchronous condensers with the prime mover disconnected). Increasing the device's field excitation results in its furnishing reactive power (measured in units of var) to the system. Its principal advantage ...
