Description
Key Features
- Over-Speed Protection: Safely shuts down turbines when rotational speed exceeds predefined thresholds.
- Dual MPU Detection: Supports active/passive magnetic pickup (MPU) sensors for accurate speed and acceleration monitoring.
- Redundant Architecture: Three-module design with “two-out-of-three” voting logic for fail-safe operation.
- Hot-Swappable Modules: Allows 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.
- Anti-Sulfur Coating: Protects against sulfur contamination (H2S/SO2) in 3C2-class environments (IEC 721-3-3 1994).
- Self-Testing: Optional automated 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.
- Data Storage: Records operational data for trend analysis and predictive maintenance.
Application Scenarios
- Power Generation: Controls and protects 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.
- Industrial Automation: Monitors rotating equipment (e.g., pumps, fans) in chemical, metallurgical, and pulp/paper plants.
- Distributed Energy: Optimizes microgrid stability in renewable energy installations (e.g., biomass, geothermal).
Advantages
- High Reliability: Redundant sensors and fail-safe logic minimize downtime in critical applications.
- Compliance: Meets international standards, including IEC 61508 SIL-3, API 670, and ATEX/IECEx for hazardous environments.
- Ease of Use: Intuitive LCD interface and Modbus connectivity simplify configuration and monitoring.
