III. Main Functional Characteristics

1. Advanced Fully Automatic Synchronization (Core Enhanced Function)

Three-phase synchronization control: Independent output of frequency, phase, and voltage bias signals, precisely coordinating with engine speed regulators and generator AVR (Automatic Voltage Regulator) to achieve complete matching of voltage, frequency, and phase.

Intelligent detection of synchronization window: Built-in high-precision synchronization discrimination algorithm, accurately capturing zero-difference closing timing to ensure zero-impact grid connection and protect generators and power grid equipment.

Synchronization failure protection: Synchronization process timeout automatically exits to prevent non-synchronous parallel connection risks.

2. Dual Mode Speed Regulation and Precise Load Control

Isochronous / Droop dual mode: Supports single-machine constant speed (isochronous) and grid load distribution (droop), and can switch without interruption.

High-precision load distribution: When multiple machines are in parallel, achieve precise power distribution, with load distribution accuracy up to ±1%.

Advanced load management: Soft loading / soft deceleration, load limit, critical speed avoidance, idle / rated automatic switching.

3. Industrial-grade Reliability and Communication

Fully isolated I/O: All signal ports are electrically isolated, with strong anti-interference (EMI/EMC) capabilities.

Multiple protections: Over-speed, overload, low oil pressure, high water temperature, etc., all-round safety interlocks.

Dual serial port communication: Supports Modbus RTU, can be connected to DCS/PLC/SCADA systems, enabling remote monitoring, programming, and fault diagnosis.

Data recording: Built-in black box function, records key operation and fault data.

IV. Typical Application Scenarios
