The present study explores an IEEE1588 Synchronizing System for smart distribution grid based on Industrial Ethernet.The paper first analyzes the communication system in distribution network and then proposed the project of time synchronizing system using IEEE1588 in distribution network.The study focuses on rational clock correcting time region segmentation, selecting the best clock source injection point and multiple redundant methods when correcting time method lose efficacy, etc.The precision of time synchronizing is better than that of 1 millisecond.
