Power distribution BAS-Link DC-Grid

Overview
The BAS-Link DC-Grid energy distribution platform from Baumüller enables intelligent interaction of multiple loads and energy sources via a shared DC link. By integrating DC-capable generators such as fuel cells, the platform provides an efficient shipboard power supply for propulsion and on-board electrical consumers while optimising weight, space and cost.

Functional structure and fault tolerance
The DC link is implemented as two independent distribution circuits that are interconnected during normal operation. If a fault occurs in one circuit, that section is automatically isolated so the remaining circuit can continue operation, increasing system availability and minimising mission impact.

Integration and benefits

• Integration of multiple energy sources (e.g. fuel cells, generators) into a common DC bus.
• Supports centralised and decentralised power architectures for flexible ship designs.
• Reduces overall system weight, footprint and lifecycle cost through shared DC infrastructure.
• Improves availability by limiting downtime via redundant independent distribution circuits.

Scope of supply
Baumüller supplies the BAS-Link DC-Grid as a system solution including drives, control units, engineering and service concepts. The company acts as system supplier and partner for shipyards, system integrators and ship owners throughout project planning and lifecycle support.
