Research on Self-Healing Repair of Distribution Network Automation Based on Multi-Intelligent Body System
The distribution network self-healing scheme is designed to work as a grid system recovery mechanism that can minimize distri-bution network faults by coordinating distributed intelligence in substations and feeders,thus ensuring the reliability of the grid operation.The distribution network automatic switching scheme is used to minimize switching operations and recover the failure-occurred grid system in the shortest time interval.The self-healing technology of distribution grid automation based on multi-intelligent body system(MAS)is proposed,and decentralized MAS system is used to realize the self-healing technology of distribution grid.Intelligent electronic devices are also used as the control center of distribution network automation for communication code transfer between servers.The use of a commer-cial IED based on the IEC 61850 protocol for self-healing operation reveals the feasibility of extending the MAS system beyond the realm of operational control centers.Finally,case study reveals that the execution time of the distribution network self-healing operation automa-tion procedure takes only 85 ms,greatly improving the reliability of the distribution network automation.
