Rapid network topology analysis method

Abstract

The invention introduces a rapid network topology analysis method, which comprises the following steps of: 1) reading data; 2) forming extension connection points; 3) forming a main bus bar; 4) forming branches; 5) reading a switch state; 6) forming a calculation bus bar; 7) forming topological islands; and 8) circulating or triggering execution. By adopting the method, the number of equipment which is required to be searched is reduced to four to eight times and the speed of network topology analysis is improved by one order of magnitude. The rapid network topology analysis method has the beneficial effects that: 1) the real-time performance of the network topology analysis in an integrated dispatching and distribution system and the requirement of a grid on the real-time performance of the topology analysis is satisfied; and 2) the result of integrated dispatching and distribution topology analysis does not influence a high-level application module in the existing energy management system (EMS), and the high-level application module in the existing EMS is not required to be modified and can be applied to the integrated dispatching and distribution system.
