Stucke Elektronik SYMAP®BCG Power Management and protection device

SYMAP® BCG is the flagship "All-in-One" solution from Stucke Elektronik. 

It is a sophisticated digital platform that combines Power Management System (PMS) logic with comprehensive Generator Protection and Engine Control. 

It is designed to be the primary controller for each generating set in a complex power plant or shipboard grid.

1. Product Description

SYMAP® BCG stands for Bus-tie, Control, and Generator protection.

 It is a microprocessor-based system that manages the entire lifecycle of a power source—from starting the engine and synchronizing with the busbar to load sharing and protecting the alternator against electrical faults.

By integrating these functions into a single unit, the BCG eliminates the need for separate PLC-based power management, external synchronizers, and standalone protection relays, significantly reducing the complexity of switchgear wiring.

3. Related Models

The BCG series is often customized for specific power levels:

SYMAP® BCG-Standard: Integrated PMS and protection for LV/MV generators.

SYMAP® BCG-D: Includes integrated Differential Protection for high-reliability generators.

SYMAP® BCG-C (Compact): A smaller form factor for space-constrained control panels.

SYMAP® BCG-HV: Optimized for high-voltage generators with PT/CT ratio scaling.

4. Application Cases

Marine Propulsion Plants: Managing multiple diesel generators on LNG carriers, tankers, and cruise ships.

Offshore Drilling Rigs: Controlling the power grid for DP3 (Dynamic Positioning) vessels where total system reliability is mandatory.

Islanded Power Stations: Managing remote microgrids combining diesel, gas, and renewable sources.

Critical Backup Power: Emergency power systems for airports and large-scale data centers requiring "black-start" capability.

5. Product Advantages and Features

Integrated Synchronizer & Load Sharer: Features high-precision automatic synchronization and active/reactive load sharing without external hardware.

Fail-Safe Operation: The 3-CPU system ensures that if the "Management" CPU fails, the "Protection" CPU remains fully functional to trip the breaker during a fault.

Black-out Prevention: Includes "Load Shedding" and "Heavy Load Inquiry" logic to prevent the grid from collapsing when large motors are started.

User-Friendly HMI: Large backlit LCD with vector diagrams, allowing operators to see the phase relationship between Generator and Busbar in real-time.

Global Certifications: Type-approved by all major marine classification societies (DNV, LR, ABS, BV, CCS, etc.).
