Improved resistance to short circuits

11.11.2011
Superconductive fault current limiters in power plants

Short circuits are expensive for power plants and electricity grids. Already during the construction of the plants, each component has to be designed to withstand the maximum possible loading in the case of a short circuit. If an incident does actually occur, downtimes and damaged system components can cause additional costs.

The BINE-Projektinfo brochure “Superconductive fault current limiters in power plants” (12/2011) presents a new kind of system for controlling short circuits that can substantially increase the safety, availability and reliability of electrical systems in power plants and when expanding electricity grids.

Superconductive fault current limiters do not influence the current flow in normal operation, since they do not provide any significant resistance. However, if the current density increases above a threshold value, the superconductivity collapses and an electrical resistance instantly forms within a few milliseconds. This helps to limit the effects of short-circuit events. Various system designs enable such components to be adapted to the specific requirements on site. The first generation of superconductive fault current limiters are based on ceramic materials. A number of prototypes are currently being tested in various locations. With the upcoming expansion of the electricity grid in Germany, these fault current limiters can help prevent expensive retrofitting and facilitate the integration of new, decentralised small-scale power plants (e.g. wind farms).

A superconductive fault current limiter was used for the first time in the Boxberg power plant in 2009. In the near future, it is planned to test a second-generation system based on metal tape with a thin coating of extremely high performing superconductive materials at the same location.

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...

Im Focus: Controlling superconducting regions within an exotic metal

Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...

Im Focus: How Do the Strongest Magnets in the Universe Form?

How do some neutron stars become the strongest magnets in the Universe? A German-British team of astrophysicists has found a possible answer to the question of how these so-called magnetars form. Researchers from Heidelberg, Garching, and Oxford used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.
