With the construction of new power systems, grid has become extremely large, with an increasing proportion energy and AC/DC hybrid connections. The dynamic characteristics fault patterns are complex; additionally, control is difficult, operation risks high, task handling arduous. Traditional power-grid relies primarily on human experience. difference in lack knowledge reserve personnel restrict accuracy timeliness handling. Therefore, this mode no longer suitable for requirements systems. Based multi-source heterogeneous data dispatch, paper proposes a joint entity–relationship extraction method dispatch processing based pre-trained model, constructs graph designs, develops fault-processing auxiliary decision-making system graph. It was applied to study provincial center, it effectively improved accident ability intelligent level management grid.
