SYMAP-BCG MUTIFUNCTIONAL CONTROL DIGITAL PROTECTION MONITOR
Technical Parameters:
Core Architecture: Microprocessor-based digital protection system incorporating real-time measurement, multi-channel control logic, and diagnostic monitoring within a single terminal block.
Protection Functions: Features an extensive software-defined protection library including overcurrent (50/51), directional overcurrent (67), over/undervoltage (59/27), over/underfrequency (81O/U), reverse power (32R), thermal overload (49), and earth fault tracking (50N/51N).
Measurement Metrics: Samples high-precision true RMS parameters for three-phase currents, three-phase voltages, active/reactive/apparent power, power factor ($\cos\phi$), and grid frequency.
Control & Interlocking: Integrated programmable logic engine optimized for breaker control, automated synchronization loops, status monitoring, and safety interlock enforcement.
Human-Machine Interface (HMI): Front panel equipped with a high-contrast graphic LCD screen for real-time vector diagram rendering, parameter adjustment, and a dedicated LED matrix for immediate alarm and trip signaling.
Communication Interfaces: Supports multiple industrial fieldbus interfaces, such as Modbus RTU/TCP, Profibus DP, or IEC 60870-5-103/IEC 61850 protocols, allowing direct integration into SCADA and substation networks.
Power Supply Range: Flexible internal power supply module designed to accept standard industrial control voltage ranges of either 24-48 VDC or 110-230 VAC/DC.
Hardware Isolation: Galvanically isolated analog transformer inputs (CT and VT paths) alongside robust optical isolation barriers on all digital I/O lines to withstand high dv/dt switching transients.
Mechanical Construction: Flush-mounted, rugged metal enclosure rated up to IP54 on the front panel, engineered for harsh, vibration-heavy environments.
Industrial Sectors:
Marine Vessel Engineering (Commercial Cargo, Cruise Ships, and Naval Vessels), Offshore Oil & Gas Drilling Platforms, Industrial Power Generation and Cogeneration (CHP) Utilities, Critical Infrastructure Backup Power Plants, and Heavy Manufacturing Facilities.
Application Scenarios:
-
Marine Main Switchboard Protection: Installed on the main electrical distribution switchboards of cargo ships and cruise liners to act as the primary protection and control relay for high-capacity onboard diesel generator sets.
-
Generator Power Grid Synchronization: Deployed in medium-voltage power plants to manage automatic synchronization, frequency tracking, and phase-matching controls before coupling synchronous generators to a shared facility busbar.
-
Offshore Platform Power Management: Integrated into oil platform switchgear cabinets to handle dynamic load-shedding sequences and execute rapid breaker trips during reverse-power or overcurrent faults, preventing complete blackout events.
-
Co-Generation Plant Intertie Monitoring: Positioned at the utility boundary of industrial co-generation facilities to continuously check the incoming grid parameters, instantly islanding the local plant if voltage or frequency drifts beyond safe operation bounds.
