GE IS200TSVCH2AED MRP246517 Industrial-Grade Turbine Speed Control & Vibration Monitoring Module (Dedicated for Gas/Steam Turbine Regulation, Compatible with GE Mark VIe DCS & Turbine Control Systems)
Product Description
The GE IS200TSVCH2AED MRP246517 is a high-integrity turbine speed control module engineered to monitor, regulate, and protect gas/steam turbines in power generation, oil & gas, and heavy industrial applications. As a core component of GE’s Mark VIe distributed control system (DCS), it works in tandem with stable power supplies like the ABB UFC911B106 to form a “reliable power → real-time speed/vibration data → precision control” loop:
Powered by the UFC911B106’s regulated DC output (ensuring consistent performance of its internal control circuits), the module receives input signals from turbine-mounted sensors—including speed pickups (to measure rotational speed), vibration transducers (to detect mechanical anomalies), and position encoders (to track valve actuation). It processes these signals via built-in high-speed digital signal processors (DSPs), comparing measured speed to pre-set setpoints (e.g., rated speed, startup ramp rates) and calculating optimal adjustments for turbine control valves (e.g., governor valves, stop valves).
Key to its functionality is integrated safety logic: if vibration levels exceed thresholds or speed deviates from safe ranges, the module triggers protective actions (e.g., valve closure, turbine shutdown) to prevent catastrophic damage. It also transmits real-time speed, vibration, and control status data to the Mark VIe DCS for centralized monitoring and historical trending—enabling operators to optimize turbine efficiency and schedule predictive maintenance. With a rugged design compliant with industrial turbine standards (e.g., ISO 8528) and support for hot-swap replacement, it is ideal for mission-critical turbine applications where uptime and safety are paramount.
Product Parameters
- Speed Control Performance
- Speed Measurement Range: 0–15,000 RPM (compatible with magnetic pickup sensors and optical encoders); resolution: 0.1 RPM (enables detection of minute speed fluctuations).
- Speed Control Accuracy: ±0.01% of rated speed (at steady-state operation); ensures turbine operates within tight tolerances for power quality and efficiency.
- Control Modes: Supports multiple operating modes—startup ramp (0–rated speed, configurable ramp time: 10s–600s), load control (speed droop: 2–10% configurable), and isochronous control (for grid-connected turbines requiring constant speed).
- Speed Input Compatibility: Accepts signals from 2 redundant speed pickups (magnetic: 0–10V AC, 50–10,000 Hz; optical encoder: 5V DC, up to 100,000 pulses per revolution (PPR)) for fault tolerance.
- Vibration Monitoring & Safety
- Vibration Input Channels: 2 independent analog input channels (supports 4–20mA DC vibration transducers, e.g., GE Bently Nevada 3300 XL); measurement range: 0–50 mm/s (RMS) or 0–254 μm (peak-to-peak).
- Safety Thresholds: Configurable dual-level alarms (warning: 80% of maximum allowable vibration; danger: 100% + 10% margin); triggers turbine trip (valve closure) within ≤10ms if danger threshold is exceeded.
- Fault Detection: Real-time monitoring of speed pickup open/short circuits, vibration sensor signal loss, and internal module faults; transmits fault codes to Mark VIe DCS for alarm logging.
- Redundancy: Supports 1+1 hot standby redundancy (when paired with a second IS200TSVCH2AED module); automatic switchover time ≤50ms to ensure control continuity during module faults.
