The loss of excitation (LOE) in synchronous generators represents a critical fault condition that can lead to severe operational disruptions and damage within power systems. Under normal conditions, ...

Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a ...

Traditional power stations are increasingly being replaced by wind and solar power plants – but that means the power grid lacks a stable pacemaker. Researchers from ETH Zurich are developing a control ...

In the future, Europe is to be dominantly powered by renewable energy. The expansion of wind and solar power capacity and the provision of sufficient power in winter are just two of the challenges ...

Energy and Environment is an interdisciplinary journal inviting energy policy analysts, natural scientists and engineers, as well as lawyers and economists to contribute to mutual understanding and ...

Scientists at Scripps Research have used rapid alternating current (AC) to selectively reduce carbonyl groups (J. Am. Chem. Soc. 2021, DOI: 10.1021/jacs.1c06572). The technique avoids side reactions ...

One major noise source of diesel engines are timing gear impacts. The structure vibration excitation mechanisms of the timing gears of different 3-cylinder diesel engines are investigated. To this end ...
