A virtual wind farm serves as a detailed digital representation of an actual facility. By precisely modelling the real components and processes, and by leveraging the simulation and calculation results derived from these models, maintenance intervals can be scheduled for the real wind farm based on actual needs (predictive maintenance). This approach can improve turbine availability and extend their operational lifespan. The digital model has various applications, including scientific research, assisting wind turbine manufacturers in technology evaluation and supporting regulatory bodies in conducting holistic assessments.
