• Identification et modélisation d'ordre fractionnaire des machines synchrones fonctionnant comme générateur

  Publikacja

  • S. Racewicz

  - Rok 2010

  W pracy przedstawiono oryginalny model matematyczny generatora synchronicznego wykorzystujący pochodne rzędów niecałkowitych. W przeciwieństwie do modeli klasycznych, zbudowanych z dużej liczby drabinek R-L, zawiera on impedancje rzędu połówkowego, które pozwalają w dokładny sposób opisać zjawiska indukcji elektromagnetycznej w szerokim zakresie częstotliwości, minimalizując jednocześnie rząd i liczbę parametrów modelu. Zaproponowany...
