Haliade-X

Summary

GTD partnered with General Electric (GE) to deliver the complete control system for the Haliade-X offshore wind turbine, covering design, implementation, validation, and commissioning. Leveraging a model-based development methodology, GTD created Simulink models for critical turbine subsystems and deployed them on the MarkVIe PLC. By implementing the Turbine Controller Software, building automated testing tools, and validating the system with a custom Test Bench, GTD ensured peak performance, reliability, and safety for one of the world’s most powerful offshore turbines.

Project Overview

• Scope: End-to-end development of the Haliade-X control, protection, and monitoring systems under contract from GE.
• Approach: Model-based design using Simulink for subsystem modeling; tight integration with GE’s MarkVIe PLC environment.
• Deliverables:
  1. Turbine Controller Software: Real-time control logic for pitch, yaw, torque, and generator subsystems.
  2. Automated Testing Tools: Custom scripts and hardware-in-the-loop (HIL) frameworks to verify controller behavior under fault conditions and normal operation.
  3. Validation & Commissioning: System validation via a bespoke Test Bench, followed by on-site commissioning support to certify industry-leading reliability and availability.

GTD’s Role & Technical Contributions

Key Benefits & Value Delivered

• Optimized Turbine Performance
  By fine-tuning control loops and leveraging real-time feedback, the Haliade-X achieves maximum energy capture, even at low wind speeds, while minimizing mechanical loads during gusts.
• Enhanced Reliability & Availability
  Automated testing frameworks and robust fault-handling logic reduce unplanned downtime, ensuring that turbines remain operational and grid-connected under challenging offshore conditions.
• Scalable, Future-Proof Architecture
  Model-based workflows allow rapid adaptation to next-generation turbine enhancements—such as updated generator configurations or advanced pitch actuators—without complete system rewrites.
• Industry-Leading Safety
  Integrated protection routines and hierarchical interlocks guarantee that the turbine automatically transitions to safe states during electrical faults, over-speed events, or mechanical anomalies.

Technical Excellence

• Simulink & PLC Integration: End-to-end code generation from verified Simulink models to MarkVIe PLC function blocks, ensuring seamless translation of control algorithms.
• Hardware-in-the-Loop (HIL) Testing: Realistic emulation of turbine sensors and actuators, allowing exhaustive pre-deployment validation of control strategies.
• Custom Test Bench: A test platform replicating full-scale turbine subsystems, enabling GTD to conduct automated, repeatable tests that mimic offshore environmental conditions.
• Continuous Integration & Regression: Automated CI pipelines trigger nightly builds and run regression tests, accelerating development cycles and ensuring code quality.
