Description
Product Overview
Stucke SYMAP-BCG is a multifunctional digital protection relay and Power Management System (PMS) controller designed for generator protection, busbar management, synchronization control, and energy system automation applications. Developed by Stucke Elektronik, SYMAP-BCG belongs to the SYMAP family of advanced digital protection devices and combines generator protection functions, power management logic, diesel/gas engine control, and programmable automation capabilities into a single compact industrial controller. It is widely used in marine power systems, offshore platforms, distributed generation plants, and industrial energy networks requiring reliable electrical protection and intelligent power control.
Stucke SYMAP-BCG integrates multiple functions traditionally handled by separate protection relays, PLC controllers, synchronizers, and power management devices. The unit continuously measures generator voltage, current, frequency, power, and power factor while executing protection algorithms such as overcurrent, reverse power, over/under voltage, over/under frequency, and generator fault monitoring. Through integrated PMS functionality, SYMAP-BCG can perform automatic generator start/stop control, load sharing, load shedding coordination, and bus-tie management, reducing system complexity and improving operational reliability.
Stucke SYMAP-BCG is designed for medium-voltage and low-voltage power generation systems where high availability and flexible configuration are required. With communication interfaces including Modbus, Profibus, CAN bus, and optional IEC 61850 capabilities, the controller can be integrated into modern SCADA, DCS, and ship automation systems. Its compact stainless-steel housing, strong EMC performance, programmable logic functions, and comprehensive diagnostic features make SYMAP-BCG a reliable solution for critical electrical infrastructure.

SYMAP-BCG
Main Features and Advantages
Stucke SYMAP-BCG provides an integrated approach to electrical power management by combining protection, control, and monitoring functions in a single intelligent device. This architecture eliminates the need for multiple standalone controllers and reduces wiring complexity, engineering effort, and maintenance requirements in generator-based power systems.
Integrated generator protection is one of the main advantages of SYMAP-BCG. The device continuously evaluates electrical parameters and provides fast protective responses against abnormal operating conditions. Functions such as overcurrent protection, reverse power protection, voltage supervision, frequency monitoring, and optional differential protection help protect generators and associated electrical equipment from damage.
The Power Management System functionality of SYMAP-BCG enables intelligent control of multi-generator installations. The controller can coordinate generator synchronization, automatic load distribution, standby generator operation, and load shedding strategies. This allows power systems to maintain stable operation during changing load conditions and improves fuel efficiency in generator-based networks.
Another important advantage of SYMAP-BCG is its programmable automation capability. The integrated logic functions allow engineers to customize control sequences without requiring an external PLC for many applications. Users can configure interlocks, alarms, operational sequences, and customized control strategies according to specific plant requirements.
Communication flexibility makes SYMAP-BCG suitable for modern automation architectures. The controller supports multiple industrial communication protocols, allowing connection with supervisory systems, ship automation systems, SCADA platforms, and distributed control systems. This enables centralized monitoring and efficient management of electrical assets.
The rugged construction of SYMAP-BCG provides reliable operation in demanding industrial environments. The compact stainless-steel enclosure improves electromagnetic compatibility and allows installation in control panels with limited space. Its high integration level reduces system footprint while maintaining comprehensive functionality.
For marine and offshore applications, SYMAP-BCG offers particular advantages by combining generator protection, PMS functions, and automation control in one device. This reduces the complexity of electrical switchboards and improves system availability in applications where power reliability is critical.
With advanced protection algorithms, integrated energy management, flexible communication, and programmable control functions, Stucke SYMAP-BCG provides a complete intelligent solution for modern generator and power distribution systems.
