摘要
本次毕业设计的题目是若水电站枢纽工程水电站厂房设计。
若水电站位于沅水一级支流巫水下游峡谷河段,电站正常蓄水位192m、、装机容量16兆瓦,是一座以发电为主,兼有防洪、旅游等综合效益的水电工程,枢纽建筑物由溢流闸坝、重力式挡水坝、右岸引水发电隧洞和引水式厂房组成。
本次设计内容主要有:机电设备(含水轮机、发电机、起重机、调速器及油压装置等)选择、水电站厂房布置、主副厂房结构设计、厂区枢纽布置、发电机楼板层结构设计。
关键字:厂房机电设备布置结构设计
Abstract
The object of this graduate design is the powerhouse of ruoshui hydroelectric hub.
Ruoshui hydroelectric station locate at the gorge, on the downstream of Wushui which is the first level branch of Yuanshui, with the normal reservoir operation level of 192 meters, the reservoir capability of billion and the installed capacity of 16MW. It take generate electricity as the lord, of course, it also have the synthesis benefits of protecting from the flood and travel. This project prised of a overflow brake dam, a gravity dam, a power house and diversion tunnels which locate on the right bank.
The main content of this graduate engineering design is: making choice of hydroelectric equipment including generator、chain block etc; arranging the power house of the hydroelectric station; designing the configuration of the main and subsidiary power house; arranging the hu
