摘要: 为提高大型水轮机方案设计的效率,对设计知识进行合理组织和设计求解。通过基元对设计知识进行描述,建立了综合特性曲线处理转轮选取的基元蕴含模型与数据存储模型。通过搜索运行区域工况点进行算法改进,建立了工况运行区域基元关联判定模型与数据顺滑模型,从而完成选型设计综合特性曲线处理过程。通过某大型水轮机选型方案设计实例,验证了方法和模型的有效性和可操作性。

Abstract: To improve efficiency of scheme design for large-scale hydraulic turbines, reasonable organization of design knowledge and its intelligent design made valuable contributions to design tasks. After describing the design knowledge with basic element, the basic element implication model of running selection and the data storage model were presented. And then, an improved searching and matching method of key points in running area was put forward, based on these, the data smooth model and the basic element interaction and judgment model of key points in running area were presented. Finally, an example of large-scale hydraulic turbines scheme design was provided to validate the efficiency and feasibility of the proposed models.
