本毕业设计来源于青海省水利水电勘测设计研究院

水电站厂房是水电站最主要的水工建筑物之一，是将水能转换为电能的综合工程设施，厂房中安装水轮机、水轮发电机和各种辅助设备。通过能量转换，水轮发电机发出电能，经变压器，开关站等输入电网送往用户。所以说水电站厂房是水（水工）、机（机械）、电（电气）的综合体，又是运行人员进行生产活动的场所。其任务是满足主要设备及其联络线、缆和管道布置的要求与安装、运行、维护的需要；保证发电的质量；为运行人员创造良好的工作条件；以美观的建筑造型协调与美化自然环境。

本毕业设计承担门源县石头峡水电站工程可行性研究阶段厂房设计部分工作。

根据已有的原始资料和该处地形图进行设计，主要内容有：厂房尺寸的确定，安装高程的确定，水轮机的选型，发电机的选型，调速系统的选型，尾水管的选型，厂房的整体稳定分析，并根据要求绘制相应的平面布置图和剖面图。

毕业设计是我们大学生实践学习的一个重要环节，它将大学四年中所学知识，有机的协调起来，系统而全面的总结了大学四年的学习成果。由于本人的水平有限，设计过程中不免有缺点和错误之处，真挚希望老师和同学们批评指正。

关键词：结构尺寸，安装高程，水轮机、发电机、调速系统、尾水管、厂房整体稳定分析。

Design General Information

This graduation project comes from the water conservancy and power In Qinghai Province and surveys and designs the research institute.

The factory building of power station is one of the main hydraulic buildings of power station, it is to change hydroenergy into the comprehensive engineering facilities of the electric energy, install hydraulic turbine, hydrogenerator and various auxiliary equipment in the factory building. Through the energy transfer, the hydrogenerator generates the electric energy, through the voltage transformer, switching station,etc. inputs the electric wire netting to send to users. Thus the factory building of power station is the synthesises of water (water conservancy project), the machine (machinery), electricity (electric), the place that operate personnel carry on producing. Its task is a requirement for meeting capital equipment and its tie line, cable and pipe arrangement and need that installs, operates, maintains; Guarantee the quality that generates electricity; Create the good working condition for operating personnel; Mould and coordinate and beautify the natural environment with the esthetic building.

This graduation project is undertaken work partly of the plant designing of stage of feasibility research of project of power station of stone gorge of Menyuan County.

Carry on the design according to existing firsthand information and topographic map of this place, the main content is as follows, the determination of the size of factory building, install high Cheng's determination, the selecting type of the hydraulic turbine, the selecting type of the generator, adjust the selecting type systematic in speed, the selecting type of the end water pipe, the whole of the factory building is analyzed steadily, and as requested draw corresponding level layout drawing and section system.

Key Word:The physical dimension, install high Cheng, hydraulic turbine, generator, adjusting the speed systematically, whole end water pipe, factory building are analyzed steadily.
