This paper is proposed a method to improve distribution automation system (DAS) restoration efficiency by including multi-agent system (MAS) and changing from centralized to distributed system. Multi-agent concept in this paper is defined by a notion from the IEEE Power Engineering Society's (PES) intelligent system subcommittee (within the PSACE Committee) working group. Intelligent distributed restoration...
Application of two new ANN-based algorithms for arcing high impedance fault (HIF) detection in multigrounded medium-voltage (MV) distribution networks is presented in this paper. The paper provides an evaluation of two new structures of artificial neural networks (ANNs) that may be used for reliable HIF detection in multigrounded as well as isolated, compensated, and grounded via small resistance...
In this paper, a protection system using a Multi-Agent concept for power distribution networks is proposed. Every digital over current relay (OCR) is developed as an agent by adding its own intelligence, self-tuning and communication ability. In order to cope with frequent changes in the network operation condition and faults, an OCR agent, suggested in this paper, is able to detect a fault or a change...
Application of wavelet transform technique to high impedance arcing fault detection in distribution networks is presented. Phase displacement between discrete wavelet coefficients calculated for zero sequence voltage and current signals at natural network frequency is tracked. The developed wavelet based HIF detector has been tested with EMTP-ATP generated signals, proving better performance than...
