Engineering systems are responsible for the core operations of the ship, including power generation, propulsion and life support.
The vessel is propelled through space by different engine systems for travel between and within star systems.
The Power Distribution Network (PDN) is made up of a number of nodes located around the vessel. A power distribution node is a junction where multiple conduits meet for the purpose of power distribution. Nodes may also perform conversion between power standards.
Correctly identifying each component node relies on a designation protocol, which includes a seven-character unique identifier (UID) and additional codes to identify the node's supported power standards and power ratings.
The designation protocol is used on control consoles where PDN nodes are monitored and managed.
Node UID
The first three characters of the UID indicates its location on the vessel, in the order DECK-SECTION-PORT/STARBOARD.
For example 5FS indicates the node is located on deck five, section F, on the starboard side.
The remaining four characters are a unique numeric code.
Power Standard
1DN: designates the node as part of the primary distribution network supplying medium voltage (1000V) DC power.
2DH: designates the node as part of the secondary distribution network supplying high-frequency (400Hz) AC power at 440 volts.
2DL: designates the node as part of the secondary distribution network supplying low-frequency (50Hz) AC power at 240 volts.
