Technical Architecture & Functional Positioning
The SYMAP F-C2B4-B1B1-A0A3-B2C0-A0 belongs to the flagship SYMAP-X family and is positioned as a complete digital replacement for traditional analog generator protection and control panels. Unlike conventional systems that require separate protection relays, AVR, synchronizer, and control PLC, this unit integrates all functions into a single compact device with full numerical processing and deterministic execution.
The core is built around a high-speed dual-core platform (ARM + DSP) that performs vectorial phasor calculation, differential protection algorithms, and excitation control loops simultaneously at 48 samples per cycle. The integrated differential protection (87G) uses phase-segregated current comparison with adaptive restraint characteristic, achieving operating times below 15 ms even with heavy CT saturation — critical for generator internal fault clearing before stator damage.
Synchronization and AVR functions operate independently of the protection core via dedicated real-time control loops, ensuring that a protection trip never interferes with breaker closing logic. The built-in power system stabilizer (IEEE PSS2A/4B compliant) actively damps low-frequency oscillations in weak grids — a feature previously requiring external excitation systems.
Typical Application Scenarios:
- Applied in medium hydropower plants (5–100 MVA) as complete generator control and protection center replacing legacy BBC, ABB Unitrol, or Alstom systems
- Used in industrial co-generation and gas turbine packages requiring fast auto-synchronization and reactive power sharing
- Serves as drop-in replacement for obsolete analog panels (e.g., GEC, Siemens GRS) with minimal rewiring via configurable I/O mapping
- Deployed in offshore wind farm converter stations needing IEC 61850 GOOSE messaging and harsh environment certification
- Utilized in emergency diesel generator sets demanding black-start capability and precise voltage/frequency control
