Research on event sequence chain based dispatch information model

In power grid, information modeling and presentation have become more and more important for operators to quickly understand what is happening in power grid. Traditional dispatch log covers a lot of categories and event records. To simplify dispatch log and help operators pay more attention to core events and get better understanding of power grid, we proposed an event sequence chain based dispatch information model. Firstly, the key parts of dispatch information were modeled. Then abductive reasoning based method was proposed to verify events into event chains. Finally, STEP(sequentially Timed Events Plotting) method was used to present different events to an event sequence chain at different time level. A case study based on this model is used to show the efficiency of proposed model and methods. Our proposed model and methods can be used as smart dispatch log, and intelligent alarm.
