During the Grand Banks Life Extension (GBLE) Project, the upgrade of the DC Switchboard was awarded to a local company ACTOM Energy.
The company was entrusted to design, manufacture, install and commission the new system. The new DC Switchboard is split into two sections. Each section, Port and Starboard, is connected to the corresponding section of the Main Switchboard, through 440/690V step up transformers.
A Bus Tie Breaker connects the two sections of the DC Switchboard. The under‐voltage (UV) coils of the Port Feeder Breaker, the Starboard Feeder Breaker and the Bus Tie Breaker in the Propulsion Switchboard are hard‐wire interlocked so that only two of the three circuit breakers can be closed at any time.
The system is controlled via a redundant PLC system with two S7‐315‐DP CPUs. The PLCs communicate with each other over an MPI link. Remote I/O stations with redundant communications monitor and control the port and starboard sections, the engine room control station, and the bridge control station. Redundant communication is achieved by two separate Profibus networks, one for each PLC. Both PLCs have full access to all the remote I/O although only one controls the I/O at any one time. A fault on one PLC or data link causes the control to be transferred from one PLC to the other seamlessly. Six Sinamics DCM drives were implemented into the design.
ACTOM Energy successfully completed the project as entrusted. The company is known as one of the major local supplier of electrical equipment, services and balance of plant to the renewable energy projects. It also holds numerous technology, distribution and value added reseller agreements with various partners, both locally and internationally
