Dynamic Digital Twin Modelling and Semi-Physical Simulation of Wind Turbine Operation
For the accurate mapping and real-time simulation requirements proposed by digital twin technology,a multi-input multi-output(MIMO)finite difference domain-hybrid semi-mechanical(FDD-HSM)digital twin modeling method is proposed,and a semi-physical simulation system of wind turbine digital twin with physical controller is established for the complex nonlinear operation characteristics of large wind turbines.The integrated dynamic MIMO-FDD-HSM model structure is constructed.Finite difference regression vectors are defined to characterize the operating conditions of the wind turbine,and finite difference space tight convex partitioning,parametric model identification,and non-parametric model training are completed under full operating conditions.The wind turbine digital twin simulation system is built in conjunction with the physical controller to carry out real-time hardware-in-the-loop simulation.The results show that the simulation system has high accuracy and real-time approximation capability.
