Onboard DC Grid
ABB Onboard DC Grid™ is a modular, fault-tolerant DC power system for ships that integrates engines at variable speed, batteries, fuel cells and other energy sources and loads.
Description
Onboard DC Grid™ is ABB's centralized, modular DC power system platform for ships, integrating energy sources and loads in a flexible, customizable architecture for simple to highly demanding vessel applications.
Key features
- Variable-speed generator operation, keeping engines near their optimal load point to cut fuel consumption, wear and maintenance
- Simplified integration of batteries, fuel cells and other DC energy sources with fewer power conversions than AC
- Less cabling than AC and up to 30% smaller overall footprint
- Lower fault propagation; fault clearing within a few microseconds
- Closed-bus operation meeting strict class requirements in hardware and software
- Handles different engines at different speeds, supporting different fuels
- Allows adding or changing energy sources (batteries, fuel cells, shaft generators) over the vessel's life
Applications
Passenger, energy, cargo and short sea vessels with small to mid-range power needs, hybrid and fully electric vessels, and newbuilds planned for future battery or fuel cell adoption. Part of ABB's power system family alongside Onboard AC Grid™ and Compact Onboard DC Grid™.
