Core Functions & Features
1. Dual-Channel Safety Synchronization
- Independent Dual Channels: Two separate hardware/software channels perform parallel synchronization checks; only simultaneous approval triggers breaker closing, eliminating single-point failure risks.
- Multi-Mode Synchronization: Supports automatic generator-grid synchronization, line/busbar paralleling, and dead-bus synchronization (synchrocheck).
- Precise Parameter Control: Monitors and regulates voltage, frequency, and phase angle to meet strict synchronization criteria before issuing close commands.
- 7 Configurable Parameter Sets: Stores independent settings for up to 7 synchronization points, enabling multi-breaker control from one unit.
2. Advanced Control & Regulation
- Automatic Governor/AVR Control: Outputs precise frequency (f+/f-) and voltage (U+/U-) adjustment signals to generator control systems for rapid synchronization.
- Real-Time Measurement: Continuously samples and calculates voltage, frequency, phase angle difference, and slip frequency with high accuracy.
- Synchronization Window: Defines adjustable acceptance windows for phase, frequency, and voltage to ensure safe paralleling under varying conditions.
- Fast Response: Executes synchronization and breaker closing within milliseconds to prevent system instability.
3. Monitoring, Diagnostics & Safety
- Comprehensive Fault Detection: Monitors for over/undervoltage, over/underfrequency, phase loss, and internal faults; triggers alarms and blocks unsafe operations.
- Event Recorder: Logs synchronization events, fault data, and breaker operations for post-event analysis and troubleshooting.
- Self-Diagnosis: Performs continuous internal hardware/software health checks and reports anomalies via indicators and communication ports.
- Visual Status Indicators: Front-panel LEDs for power, run, sync, and fault status for local monitoring.
- Breaker Interlock: Prevents simultaneous closing of multiple breakers and enforces safety interlocks for system protection.
4. Industrial-Grade Reliability & Integration
- Redundant Power Supply: Optional dual power inputs ensure uninterrupted operation during power source failures.
- Modular Design: Compact rack-mount form factor for easy integration into control panels and switchgear assemblies.
- Protocol Compatibility: Seamlessly connects to SCADA, PLCs, and power management systems via standard industrial protocols.
- Long Service Life: Designed for 24/7 continuous operation in harsh industrial and power system environments with minimal maintenance.
Application Scenarios
