A Multiagent and IEC 61850-Based Fault Location and Isolation System for Distribution Network with High PV Integration – A CHIL Implementation

摘要

The ever-increasing integration of renewable distributed generation sources, for instance photovoltaic systems, into the French medium-voltage distribution has imposed several challenges to its conventional fault location and isolation system. Several researches have indicated that the present fault location and isolation system would be unable to deal with the bidirectional characteristics of the fault currents in such multi-source distribution network. On the other hand, there has been a considerable number of recently published papers that proposed to apply multiagent system and IEC 61850 communication standard for tackling these issues and the further practical applications are rather promising. However, the validation of these approaches was mainly carried out in software environments. Although, a few papers have proved the effectiveness of their systems by using Hardware-In-the-Loop technology, the interaction amongst realistic hardware equipment such as IEDs and agents was often ignored. Therefore, this paper aims at developing a novel MAS- and IEC 61850-based fault location and isolation system that can effectively operate in distribution network with high penetration of photovoltaic systems.
