Abstract

The present invention discloses a method for automatically mapping a domain network topology, and specifically relates to the technical field of power grid topology maps. The method obtains the first important value of each power grid device contained in a target power grid area, as well as the corresponding coverage coefficient, failure coefficient and disaster impact coefficient, and finally obtains the second important value. The power grid devices are preliminarily screened according to the second important value to obtain preliminary power grid devices; a power grid domain network topology map is drawn according to the preliminary power grid devices as a first topology map, and the first topology map is simulated, and the nodes in the first topology map are screened according to the simulation results to obtain final important nodes; a power grid domain network topology map is generated according to the final important nodes as the final power grid domain network topology map. In this way, the nodes are reasonably simplified, so that the power grid domain network topology map can more accurately reflect the actual state of the power grid, so that dispatchers and operators can quickly understand and use it, thereby ensuring the accuracy of dispatching decisions.
