Core Function
- High-Precision Servo Valve Control
Electro-hydraulic Servo Drive: Precisely controls the displacement and pressure of the electro-hydraulic servo valve (EHSV) via a 4-20mA analog or digital signal, enabling millimeter-level adjustment of steam/fuel valves.
Dynamic Response Optimization: A built-in PID algorithm supports millisecond-level closed-loop control (typical response time < 50ms), ensuring turbine stability during sudden load changes.
- Redundant Fault-Tolerant Architecture
Triple Modular Redundancy (TMR) Support: Utilizes three independent control circuits and employs a majority voting mechanism to mitigate single points of failure.
Hot-Swap Design: Supports online replacement of faulty modules without disrupting turbine operation (switching delay < 100ms).
- Multi-Protocol Industrial Communication
Integrated Communication Interface: Natively supports protocols such as Modbus RTU/TCP and PROFIBUS-DP, enabling seamless integration into DCS/SCADA systems. Real-time data interaction: Collects and uploads 200+ parameters per second (such as valve position feedback, drive current, and temperature status), and supports remote monitoring via the OPC UA protocol.
