TurboNet DASH2™ Gas Turbine Control System Retrofits
TDS Offers Cost-Effective, Comprehensive, Human-Machine Integrated Control System Retrofit Solutions for Gas Turbines, Using Advanced Algorithms and OEM-Compatible Designs to Optimize Performance and Reliability.
Flame Scanner Upgrade
Replace Costly OEM UV Sensors, Such as Those From Honeywell, and Their Specialty Interfaces With Third-Party Flame Scanners—Improving Turbine Reliability and Reducing Hardware Expenses.
Redundant Instrumentation
TDS Maintains Redundant Signal Paths (LVDTs, Servo Coils & Magnetic Pickups) so a Single Sensor Fault Won’t Interrupt Your Control System.
Dynamic Bias Application
Exhaust-Temperature Control Biases (Water Flow, CPD, CPR, Ambient Temp, Discharge Temp, Humidity, Load, Fuel Demand) Are Applied in Real Time Based on Actual Operating Conditions.
TurboNet DASH2™ Gas Turbine Control Upgrades
Performance Control
- Reuse of Existing Instrumentation
- In Most Cases, Your OEM-supplied LVDTs, Flow-Divider Pickups, and Servos Can Be Kept—No Expensive Valve Upgrades Required.
- Load Control
- Algorithms Maintain a Stable, Pre-Selected Set Point Under Changing Operating Conditions.
- Speed Control
- Proportional Speed-Droop Controller per IEEE Standards, With Optional Isochronous Mode. Closed-Loop Megawatt Droop Sharing Ensures Precise Load Sharing in DLN Machines.
- Acceleration Control
- Dynamic Acceleration Set Point Adjusts in Real Time to Ensure Smooth, Controlled Turbine Startups Within Safe Operating Limits.
IGV Temperature Control & Matching
- IGV Temperature Control
- Hydraulic IGV-Positioning Algorithms Optimize Exhaust-Temperature Regulation, Improving Efficiency and Enabling Stable, Low-Emission Operation at Reduced Loads.
- IGV Temperature Matching
- Advanced Logic Regulates Exhaust Temperature to Match Steam-Turbine-Chest Set Points, Reducing Thermal Stress and Enabling Faster Startups.
Thermal & Surge Protection
- Exhaust-Temperature Control
- Combines Isothermal and Biased Control Algorithms. Bias Inputs Include:
- Water Flow
- Compressor Discharge Pressure (CPD)
- Compressor Pressure Ratio (CPR)
- Ambient Temperature
- Compressor Discharge Temperature
- Air Humidity
- Load
- Fuel Demand
- Combines Isothermal and Biased Control Algorithms. Bias Inputs Include:
- Optional Thermocouple Distribution
- Distribute Exhaust Thermocouples Across Multiple Modules to Minimize Impact of Any Single Sensor Failure.
- Inlet-Bleed-Heat Control
- Compatible With OEM Designs, Supporting Both Open-Loop (Old Manifold) and Closed-Loop (New Manifold) Configurations for Optimal Heat Management.
- Surge Control
- Regulates Bleed Heat, Adjusts IGVs, and Modulates Fuel Supply to Prevent Compressor Surging—Especially in Larger-Frame Machines.
