Digital Simulation & Hardware-in-the-Loop
Fully digital simulation
Digital models represent the turbine, pitch system, converter and operating environment for teaching, scenario exploration and fault training.
Hardware-in-the-loop simulation
Connect a physical main-control PLC to real-time models through I/O and communication interfaces for closed-loop testing of interfaces, control logic and injected faults.
Configured for the intended use
Select models, controllers and test scenarios for training or engineering validation. Physical pitch rigs and converter controllers are separately scoped extensions.
INTERACTIVE TRAINING
Explore pitch response and feedback
Choose a teaching scenario, adjust the command, and compare command, response and feedback. Follow the signal chain before deciding what to check next.
Anonymous teaching demo
Simplified teaching model · relative response; no live turbine connection.
Technical Training: Simulation and Course Design
Normal operation and system understanding
Study digital startup, grid connection, generation and shutdown. Explain how wind, speed, pitch, torque and power interact.
Interface checks and blind fault exercises
Check I/O, units and timing. Inject sensor, communication or interlock faults. Learners test hypotheses and verify recovery.
Assessment and AI-assisted review
Retain curves, events and actions. Assess essential checks, action sequence and reasoning. AI assists review; instructors approve scores.
Main-controller HIL arrangement in the training concept
- Digital turbine and environment
Digital pitch and converter models - I/O and communication
Commands, feedback and fault signals - Physical main-control PLC
Closed-loop operation and logic tests
Training concept: a physical main-control PLC with digital plant models. Scope and acceptance are project-specific. Learning outcomes require assessment.
HIL Simulation: Interfaces and a Hydraulic Test
Interfaces and system integration
Test DI/DO, analog, PT100, Profibus and SSI interfaces. Integrate safety-chain, yaw, hydraulic and startup/grid-connection logic.
Example sequence and signals
In maintenance mode, establish pressure, then command partial depressurization. Log pump and pressure signals; check sequence, target and reset.
Interpretation and records
The report case uses about 150 to 35 bar. Retain versions, injections and traces. Do not transfer these settings directly to other turbine models.
Supplied test report, pp.22, 32–34. Simplified model with accelerated settings, not field data. Reference only; no Dasheng delivery or universal acceptance claim.
