摘　　要：针对目前水轮机选型设计工作繁琐、效率低且设计质量差的问题,探讨水轮机选型设计软件包的开发,详细阐述软件包开发中的数据处理和数据库的创建与管理.根据选型所需数据特性和功能对数据库结构进行模块划分,采用离散与回归拟合的方法对水轮机模型综合特性曲线进行数据处理,从而在Microsoft Access环境下创建水轮机选型设计数据库.实例计算验证该数据库完全满足水轮机选型设计软件的需要,并大大提高了水轮机选型设计的速度与质量.The process of type-selection design of hydraulic turbine was much complicated with low efficiency, and unsatisfactory design quality. Aimed at these problems, the development of software package for type-selection design of hydraulic turbine was investigated, where the data processing and the creation and management of database was expounded. According to the characteristics and functions of the data related to type-selection design, the structure of database was created in the environment of Microsoft Access, where the module setting was conducted for the database, the data processing was performed with discretization and regressive curve fitting for the combined characteristic curves. It was verified by an illustrative computation that the database obtained would completely meet the need of the software package of the type-selection design, and it could greatly enhance the speed and quality of the design.
