Wind turbine sequence modeling based on secondary parametric technology

针对常规建模方法在庞大复杂风电机组应用上的不足,在建立单台风电机组全参数化模型的基础上,以风电机组序列整体为研究对象,根据同序列不同功率机组之间各零部件设计参数变化规律,研究应用二次参数化技术和参数序列化方法实现了高效的风电机组模型建立与管理;并结合三维模型参数驱动技术,研发了风电机组序列建模系统,可有效减少建模和造型工作量、降低设计失误率、提高设计效率,验证了该建模方法的正确性与合理性。

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.
