Fault identification in electrical power distribution system using combined discrete wavelet transform and fuzzy logic

Predictive Data Mining Techniques for Fault Diagnosis of Electric Equipment: A Review

“…Other works that have used the WT are the systems for electric power distribution. Jamil et al [106] implement an algorithm based on fuzzy logic that uses the DWT to identify 10 different types of faults in an electrical power distribution system. For high impedance fault detection in electrical distribution networks, the WT extracts dynamic characteristics to feed a decision-making system based on SVM [107].…”

Method of Single Phase Short Circuit Detection on Overhead Transmission Lines of an Industrial Plant Electric Power Supply System

“…Алгоритм выявления повреждений в сети с распределенной генерацией и последующего восстановления нормальной работы рассмотрен в [14]. Оптимизации размещения устройств ОМП в электрической сети, действующих на основе генетического алгоритма Чу-Бэсли, посвящена статья [15]. Алгоритм идентификации вида повреждений на основе нечеткой логики с использованием дискретного вейвлет-преобразования разработан авторами [16].…”

Intelligent Fault Diagnosis in a Power Distribution Network

“…This was the case in [1], where fuzzy logicbased fault identification in an electric power distribution system was studied and proven to produce accurate classifications of fault types. In addition, the fuzzy logic method was used in combination with discrete wavelet transform and resulted in accurate fault identification [2]. In [3], the data collected by alarms and protection relays in a power network was analyzed with neurofuzzy techniques.…”
