    2. Key Points Simulation Model Requirements andSpecifications Control Electrical Mechanical EmbeddedSoftware • Efficient design of wind turbinesrequires a smooth, continuousdevelopment process • The ability to easily adjustthe level of model fidelityenables earlier detection ofintegration issues • Automatically documentingtests can speed up designiterations and provide necessaryproof of system performance PLC HIL Actuator(Ideal) System (Include) Inputs Actuator(Realistic) System (Ignore)

    3. Agenda • Overview of wind turbine model • Benefits of the Model-Based Design process • Linking requirement documents and simulation model • Determining more detailed requirements • Testing system integration • Automatically performing and documenting tests

    4. Traditional Development Process Pitch Requirements and Specifications Blades Geartrain Generator Hub Design and Implementation Electrical Control EmbeddedSoftware Mechanical Yaw Tower Integration and Test Grid

    5. Traditional Development Process Requirements and Specifications Requirements are unclear, incomplete, and not integrated in design process Design and Implementation Electrical Control EmbeddedSoftware • Separate simulation models are difficult to integrate Mechanical Errors are found too late in the process using expensive prototypes Integration and Test

    6. Model-Based Design Process Save time by developing in a single simulation environment Simulation Model Requirements andSpecifications PLC HIL Produce better designs by continuously comparing design and specification Electrical Control EmbeddedSoftware Mechanical Lower costs by using HIL tests and fewer hardware prototypes
