水轮机选型是水轮机及辅助设备这门课的重要章节,目前的教材落后于实际工作中的选型设计,因此对这个章节进行项目化设计,让学生在项目中学习显得尤为重要,首先给学生发放任务书,在任务书中以某电站的实际参数为基础,引导学生进行选型,其中对电站的装机容量进行两台机和三台机的比较,引导学生选择合适的水轮机及合适的装机台数。一、任务书设计如下(1)根据水文水能等综合经济比较及装机容量比较结果,本电站总装机容量确定为20MW。本站加权平均水头为66.66m,考虑到适当减
Turbine selection is an important chapter of the course of water turbine and auxiliary equipment. The current teaching materials are lagging behind the actual selection of design work. Therefore, it is very important for students to study in this project. Distribute mission statement, in the mission book based on the actual parameters of a power station, to guide students to carry out selection, in which the power station installed capacity of two machines and three machines compared to guide students to choose the right turbine and the appropriate installation Number of units. First, the design of the mission statement is as follows: (1) According to the comprehensive economic comparison of hydrology and water energy and the comparison of installed capacity, the total installed capacity of this power station is determined to be 20MW. Weighted average head of 66.66m, taking into account the appropriate reduction
