水轮机选型设计的任务是确定水轮机的主要性能参数和结构控制参数 ,完成水轮机的流道设计。它需要丰富的设计知识和设计经验。现行的水轮机选型设计基本上靠手工完成 ,参数确定、性能计算、图表查找相当繁琐 ,直接影响水轮机设计的质量和效率。把基于实例的推理技术引入水轮机选型设计 ,探讨了一个基于人工智能技术的水轮机选型设计系统。 Turbine selection design task is to determine the main performance parameters of the turbine and structural control parameters to complete the turbine runner design. It requires a wealth of design knowledge and design experience. The current design of turbine selection basically completed by hand, determine the parameters, performance calculations, chart lookup quite cumbersome, a direct impact on turbine design quality and efficiency. The case-based reasoning technology is introduced into turbine type selection design, and a turbine type selection design system based on artificial intelligence technology is discussed.
