II. Core Functional Characteristics

Full-condition intelligent control: Speed control, load control, isochronous synchronization control, seamless adaptation to single unit, grid connection, multi-unit parallel operation, and island grid scenarios.

One-click automatic synchronization: Built-in microprocessor synchronizer (PWM output), automatically precisely matching frequency, phase, and voltage, achieving zero-impact grid connection.

Precise load management: Supports sag control + isochronous load distribution + soft load transfer, precise power distribution among multiple units in parallel, no impact on load fluctuations.

Triple safety protection: Over-speed, under-speed, vibration, shaft displacement, low oil pressure, high exhaust temperature, reverse power, load rejection, etc., all-round protection.

Dual valve independent drive: Independently controls the main steam valve / regulating valve, suitable for single-valve / dual-valve complex steam turbine systems.

Dual serial ports + redundant Ethernet: RS-232, RS-422 dual serial ports + redundant Ethernet, supports GAP, Modbus, Profinet, DCS remote monitoring.

Advanced data recording: Built-in black box function, high-speed sampling, long-term storage of critical operating data, supports fault traceability, vibration analysis, performance diagnosis.

Remote diagnosis and maintenance: Remote programming, parameter adjustment, fault diagnosis, program upload/download, enabling unmanned remote operation.

Industrial-grade explosion-proof: Class I, Div 2 explosion-proof certification, suitable for hazardous environments such as petrochemicals and offshore platforms.
