This book elaborates in depth knowledge for efficient detection and classification of various power system faults (such as LG, LL, LLG and LLLG) based on some advanced signal processing methods and approaches. It mainly proposes an appropriate fault index based on features extracted from current and voltage signals using the Alienation coefficient and Wigner distribution function. The fault index (FI) is computed using element to element multiplication of current-based Wigner distribution index (WD-index) and voltage-based alienation index (ALN-index). The performance of the proposed...

Dieses Buch vermittelt fundierte Kenntnisse zur effizienten Erkennung, Kategorisierung und Abschätzung verschiedener Kurzschlussfehler in Stromnetzen wie LLLG-, LLL-, LLG-, LL- und LG-Fehler auf der Grundlage fortschrittlicher Signalverarbeitungsmethoden. Ein effizienter und effektiver Schutz gegen diese Fehler in einem modernen Stromversorgungssystem wird mit der zunehmenden Integration von erneuerbaren Energien (wie Solarenergie, Windenergie, Geothermie, Biomasse usw.) in das bestehende Netz zu einer anspruchsvollen Aufgabe für alle Ingenieure und Praktiker im Bereich der Stromversorgung....

Ce livre présente des connaissances approfondies pour une détection, une catégorisation et une estimation efficaces de divers défauts de court-circuit dans les réseaux électriques, tels que les défauts LLLG, LLL, LLG, LL et LG, sur la base de méthodes avancées de traitement du signal. Une protection efficace et efficiente contre ces défauts dans un système électrique moderne est devenue une tâche difficile pour tous les ingénieurs et praticiens des systèmes électriques avec l'intégration croissante des énergies renouvelables (telles que l'énergie solaire, l'énergie...
