Autonomous control strategy for fault management in distribution networks

Transient selectivity for enhancing autonomous fault management in unearthed distribution networks with DFIG-based distributed generations

“…Finally the primary substation recloses circuit breaker and sends a message to the control center to be updated. As described in [33], this autonomous control was presented depending on monitoring the fundamental phasors taken from conventional fault current indicators distributed over the feeder. Such fault indicators are not suitable for unearthed and compensated networks.…”

“…This process continues sequentially until reaching the faulty segment. A further step was realized by the autonomous control strategy aiming to reduce a number of activated communication hops and, accordingly, the communication latency [33]. After opening the circuit breaker and concerning the autonomous principles, each secondary substation that has its fault indicator detected the fault sends a message to the downstream substation.…”

Visión General, Características y Funcionalidades de la Red Eléctrica Inteligente (Smart Grid)

“…Lo anterior, como mecanismos de optimización en la generación de energía mediante el seguimiento perfecto de las fluctuaciones de la demanda de la carga. Así mismo, el control inteligente puede utilizarse para la detección y reconfiguración autónoma de fallas (Tarhuni et al 2015). La investigación desarrollada en Reddy et al (2014) destaca los diferentes métodos de las características importantes de las SG; Integración, Control, Comunicación y Medición (ICCM).…”

Using a Multi-Agent System for Monitoring Indicators of Quality of Service in Power Distribution Networks

“…Esta bateria de testes foi executada 10 vezes de forma automática utilizando uma estação de trabalho, o que totalizou 1000 testes.A plataforma SQ-MAS processou corretamente a interrupção 997 vezes, podendo estimar sua confiabilidade 99,7%. Este valor é compatível com os reportados em [16] para SMAs de monitoramento de falhas em redes de distribuição usando métodos analíticos. As falhas foram provocadas pela perda de mensagens durante o processo de comunicação entre agentes.…”
