Method and system for calculating electrified state of electrical network

The invention belongs to the technical field of power systems, and particularly relates to an electrical network electrification state calculation method and system. The electrical network live-line state calculation method comprises the following steps: acquiring an electrical network topological graph of an initial live-line state; obtaining electrified state updating information; matching the electrified state update information with the electrical network topological graph of the initial electrified state to obtain at least one initial electrical network topological sub-graph, the initial electrical network topological sub-graph representing a topological structure with a linkage relationship and a topological sub-graph composed of a plurality of network nodes and a plurality of edges with attribute data changes; recalculating the live state of the network nodes in the initial electrical network topology sub-graph according to the live state update information to obtain a target electrical network topolog
