Description
Key Features
- Over-Speed Protection: Safely shuts down turbines when rotational speed exceeds predefined thresholds.
- Dual MPU Detection: Uses active/passive MPU sensors to monitor speed and acceleration, ensuring accurate fault detection.
- Redundant Architecture: Three-module design with “two-out-of-three” voting logic for fail-safe operation.
- Online Maintenance: Hot-swappable modules allow replacement without interrupting system operation.
- Event Logging: Non-volatile memory stores up to 50 trip/alarm events and 20 over-speed records with real-time clock timestamps.
- Conformal Coating: Protects against sulfur contamination (H2S/SO2) in harsh environments (IEC 721-3-3 Class 3C2).
- Auto-Testing: Optional automated self-test routines verify module functionality and report results via Modbus.
Functional Highlights
- Precision Control: Adjustable speed bands and acceleration thresholds tailored to specific turbine requirements.
- Alarm Management: Configurable relay outputs for pre-trip warnings and emergency shutdowns.
- Diagnostics: Built-in tests for sensor validation and circuit integrity checks during operation.
- Scalability: Supports cascading configurations for multi-turbine systems in power plants.
Application Scenarios
- Power Generation: Controls gas turbines, steam turbines, and hydro turbines in thermal power plants and cogeneration facilities.
- Oil & Gas: Safeguards compressor turbines on offshore platforms and pipeline stations.
- Marine Propulsion: Ensures safe operation of shipboard turbines for propulsion and auxiliary power.
