Naval Electric Power System Design

The primary aim of the electric power system design will be for survivability and continuity of the electrical power supply. To insure continuity of service, consideration shall be given to the number, size and location of generators, switchboards, and to the type of electrical distribution systems to be installed and the suitability for segregating or isolating damaged sections of the system.

Notional In-Zone Architecture

• PCM-1A

– Protect the longitudinal bus from in-zone faults

– Convert the power from the longitudinal bus to a voltage and frequency that PCM-2A can use

– Provide loads with the type of power they need with the requisite survivability and quality of service

• PCM-2A

– Provide loads with the type of power they need with the requisite survivability and quality of service

– IPNC (MIL-PRF-32272) can serve as a model

• Controllable Bus Transfer (CBT)

– Provide two paths of power to loads that require compartment level survivability

Energy Storage

• Many Potential Uses for Energy Storage

– Reduce rolling-reserve requirements by providing short-term hold-up of loads while a generator is being brought online.

• Could be important for pulse power loads

– Holding up a bus while long-term interrupt loads are shed in an orderly manner.

– Providing startup power to generator sets in a “dark ship” start.

– Provide pulse power to loads.

– Level loading to delay bringing on an additional generator.
