Fault Location and Isolation for Distribution Network with DGs Based on Intelligent Multi-Agent System

摘要

In this paper,a distributed autonomous control system based on intelligent multi-agent system(IMAS)is proposed.The framework for IMAS composed of control and protection intelligent agents(CPIAs)is introduced.The detailed structure and protection schemes of CPIA are illustrated.A simple distribution network with DGs is built on the simulation platform of DIgSILENT.The simulations provide persuasive evidence that IMAS can efficiently and accurately locate and isolate the faults.It is evident that IMAS can react faster than traditional relay protection and promote the reliability of distribution network.
