✦ Synopsis
An expert system has been developed for switching operations of network restoration of power systems. The proposed method restores the blackout area in a power system by using sensitivity analysis and heuristic rules. The rules are categorized into flow-control rules, energization rules, line and bus-bar switching rules, and load-shedding rules. The switching (opening~closing) operations of transmission lines, transformers, substation feeders and bus-bars are used for the network restoration described in this paper. A new model for bus-bar switching in a substation is also proposed. The representation of the power-system equipment has hierarchical data structures for the real-time recognition of a network topology.
