Power Distribution Data The electrical distribution system is modeled after the proposed MVDC architecture circulated by the U.S. Navy [Doerry 2016] as depicted in Figure 3. Main bus distribution voltage is 12 kV (+-6kV). The notional ship described herein uses four electrical zones instead of six and is modified to accommodate the equipment selected for this ship design, but uses the same paradigm for distribution, e.g. cross-zone connections between ac load centers in adjacent zones, dedicated converters for electrical loads greater than 1 MW, and a combination of bus nodes, power conversion modules (PCM 1As), integrated power node centers (IPNCs) and ac Load Centers (ACLCs) to provide the required power supply. The resultant power distribution system is depicted in Figure 4. Note that all loads are individually switched; although some ports on the Bus Nodes, ACLCs and IPNCs appear to have multiple loads connected to a single port, this is a rendering problem and does not indicate that the loads are switched as a group. Similarly, cables that appear coincident are actually separate. Figure 3. Proposed Navy distribution system [Doerry 2016]
