Substations play an important role in power systems. The application of the IEC61850 standard changes the situation of the traditional substation greatly. The information in the intelligent substation is rich, but it is difficult for the operators to digest them in a short time without an effective assistant tool. A fault diagnosis method which uses the alarming information of the primary and secondary...
This paper presents a new method of the distribution network fault diagnose based on data mining. This method uses the fault information produced in the process of distribution network fault handling to study the spatial and temporal characteristics of distribution network fault. It uses APRIORI algorithm to establish database of fault attributes and mine the association rules of fault information...
The main fault diagnosis algorithms of traditional substation are based on the protections and breakers. And they have not concerned the influence of abnormal communication network to the stable operation of the intelligent substation. Based on the questions mentioned above, this paper introduces the fault information of the intelligent substation first of all, which contains the static configuration...
This paper proposed a new power grid fault diagnosis model combining Petri nets and grid computing. It includes the power grid computing system's structure, software service and algorithm. The model can use the high performance computing method and distributed environment of grid computing. At the same time, Data grid system can offer table, efficient and unified information resources for the power...
