PDN schematics appear frequently on vessel consoles, to assist with the management and monitoring of power distribution to the systems controlled by the console. Where a PDN schematic is required on a console, a schematic module is added in the required space using the Console Designer. The schematic may then be drawn in that space (or a pre-drawn schematic added).
Power Distribution Network (PDN) schematics are included on consoles to provide an overview of available power sources and to allow for the configuration of those sources. Power sources and vessel systems connected to them are all represented on the PDN as*nodes. Nodes are connected by conduits which provide an overview of available distribution pathways for power.
The generation subsystem converts thermal energy (in the form of pressurised steam) to mechanical energy power by a turbine assembly which is then converted to electrical energy using an alternator assembly.
The reactor coolant system is designed to remove thermal energy from the reactor and transfer it to a heat exchange system for the creation of steam, which is in turn used to drive a turbine for the generation of electrical power.
The Power Distribution Network (PDN) has a large number of identical components located around the vessel. Correctly identifying each component, where it is located and how it and other components are linked relies on a precise designation system.
The vessel’s Power Distribution Network is a highly redundant, layered distribution system for delivering power from generation and auxiliary power sources to vessel systems.
