Lucent Technologies Galaxy Power System 4848/100
Issue 5 June 2000 System Description 2 - 5
Architecture, continued
Centralized Figure 2-4 shows GPS 4848/100 components configured in a
centralized architecture; Figure 2-5 provides a view of the centralized
architecture initial and growth cabinets. Rectifiers, dc distribution
panels, and batteries are cabled to external busbars where a single
system shunt is provided to measure total system current. The initial
cabinet contains ac distribution, rectifiers, the controller, and
termination points for the system interconnect cables. Growth cabinets
contain ac distribution, rectifiers, and cable termination points. A
separate cabinet provides load distribution and protection facilities and
may include a load disconnect/reconnect feature.
This architecture requires extensive up-front planning to determine the
ultimate system capacity and engineering to size the external busbars
appropriately; however, the system plan is not constrained to dedicated
layouts as required for distributed architecture systems.
