Wind energy turbines and associated control systems, generators and distribution networks
The multi-domain modelling capability of Dymola can be used to model wind turbines and their associated control systems, generators and distribution networks. The component oriented modelling methodology accelerates model development to enable the prediction of the loads within the system and enable the investigation of control issues such as blade pitch angle control and orientation for best yield.
Using the Modelica Standard Library the complete mechanical, electrical and control parts of the wind turbine can be modelled. Where Hydraulic drives are used instead of conventional gearboxes the Dymola Hydraulics library can supply the necessary component models to include the complete hydraulic drive in the system model. Structural compliance of the turbine blades can be included using the FlexBody library to incorporate a Finite Element Model of the blade in to Dymola.
HIL simulation gives comprehensive wind turbine system models in real-time
Dymola’s support for HIL simulation allows the comprehensive wind turbine system models to be compiled and simulated in real-time. This enables the real ECU and control software to be developed using rapid prototyping and validated using HIL simulation.
Using simulation to develop the control systems can help in developing the advanced control algorithms needed to include features such as gust tracking which requires a rapid response of the wind turbine actuators to efficiently capture energy from wind gusts. Simulation of these types of events also enables the system performance to be evaluated over the wide range of expected and extreme operating conditions to ensure that all the parts within the system can cope with the loads and currents generated or that the control system can adequately predict the overload conditions and adjust the operation of the wind turbine to avoid them.
