Current-voltage characteristics and superconducting state stability in composites
نویسندگان
چکیده
The influence of the electric field dependence of the differential conductivity on superconducting state stability in multifilamentary superconducting composites is studied theoretically. The obtained stability criterion allows one to determine the upper limit of the values of transport current and background electric field in the superconductor. To illustrate the theory, the superconducting state stability is studied in a wire in a range of sufficiently high magnetic fields.

In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...

We report measurements of the resistance and the current-voltage characteristics of aluminum thin films which have two regions of different superconducting transition temperatures. Local suppression of the transition temperature is achieved by the use of a CF4 reactive ion-etching technique. A small gradient in the transition temperature is induced around the lithographically defined etched-une...

In the event of voltage sag at the nearing of a wind park, severe currents may pass through the power electronic devices of the Doubly Fed Induction Generators (DFIGs). Hence, according to the Low Voltage Ride Through (LVRT) requirements, the wind parks are allowed to disconnect from the network after a certain time. Therefore, to avoid such actions, the LVRT requirement of wind parks is consid...
