Electrical energy distribution network in a transport vehicle, such as an aircraft, and an electrical installation in an aircraft

An electrical energy distribution network in a transport vehicle, such as an aircraft, includes nodes to which at least one power supply source and at least one equipment can be connected by external links. The nodes are interconnected by internode links forming at least one mesh in a meshed network, each mesh being polygonal of order higher than or equal to three, at least one node of each mesh being an active node controlled by a management unit. The active nodes include switches and transmit physical operating characteristics measurements to the management unit, which configures the active nodes according to said measurements so as to enable each equipment to receive power supply via the meshed network. Flexibility in configuration of the electrical energy distribution network is thus achieved.
