Abstract: According to the disadvantages of conventional modeling methods for large and
complex wind turbines, a highly efficient modeling method is proposed in this paper. Based on
a fully parametric model of a single wind turbine, it took the whole sequence of wind turbines as
the research object, and realized the fast modeling via secondary parametric technology
according to the change law of design parameters of different wind turbines in the same
sequence. A sequence modeling system for wind turbines was also developed by combining
with parameter-driven modeling technology. The system can effectively reduce the workload
and design error rate, improve design efficiency, and prove the correctness and rationality of the
modeling method.
