PDN nodes

Power distribution nodes are used to route and convert power across the vessel's network of power conduits. Each node is connected to both upstream conduits (which deliver power from other nodes closer to power generation systems) and downstream conduits (which distribute power to other nodes closer to the vessel systems that consume power). A node will typically convert power to a new standard before distributing to downstream nodes, with distribution parameters configurable for each node. Each node typically has a number of both upstream and downstream conduits to ensure redundant power routing options and for efficent power distribution.

PDN nodes manage the conversion and distribution of power from power generation systems to the vessel systems that consume power. A node receives power via conduits connected to its upstream interface and will typically convert the upstream (supply) power standard to a different downstream power standard (for example high voltage or frequency to low voltage/frequency). The node will then distribute power to conduits connecetd to its downstream interface. Each node is constructed for a specific standard conversion and cannot be configured to receive or distribute alternative power standards. 

Each node has a control interface which allows the allocation of power to downstream conduits, allowing management of power routing.

Nodes are connected to conduits via conduit taps. A conduit tap provides access to all other nodes on that conduit, depending on whether the conduit is connected on that node's upstream or downstream interface. For example, a connection on a node's upstream interface (which receives power) will give access to power from all nodes with a downstream connection (which supplies power) to that conduit.

Most nodes are distribution nodes that have both upstream and downstream interfaces. The PDN also considers power supply systems and major vessel systems as nodes, known as terminating (single-interface) nodes. Power supply systems are source nodes (they supply but do not receive power) and major vessel systems are consumption nodes (they receive but do not supply power).
