Investigations of Influence on Power Quality of Superconducting Fault Current Limiter

چکیده
Waveforms obtained from a superconducting Fault Current Limiter are investigated using the Prony modelling technique. Comparable measurements with the use of standard tools of spectral analysis (like FFT) fail because of short data available and low levels of higher spectral components. Streszczenie. W pracy przedstawiono wyniki analizy widmowej prądów i napięć zarejestrowanych w obwodach z nadprzewodzącym dławikiem przetężeniowym. Zastosowano metodę parametrycznego modelowania za pomocą metody Prony. Klasyczne metody oparte na FFT zawodzą w tym przypadku z powodu krótkich sekwencji danych, niestacjonarności przebiegów i niskiego poziomu wyższych harmonicznych.

Power system protection at transmission and distribution levels based on overcurrent relays is essential based on their properties such as detection, stability, high speed, backup and error correction accuracy. Since distributed generation sources are connected to the power grid, they not only increase the short circuit level of the grid, but also disrupt the set point of main and backup relays...

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...
