This design, the hydropower station project layout, select the turbine generator set, water diversion system design, power station plant layout design, thematic design for the intake. Which focuses on selected turbine generator sets, including the choice of unit Number of units, the unit capacity and turbine models, turbine size, volute form, wrap angle, the choice of the size of imports, the form of a draft tube size selection, the corresponding generator model size, the governor and the choice of the hydraulic device. Difficulty in the design of water diversion system, including inlet design, the layout design of the pressure pipe. The main purpose is to train students to apply the knowledge and skills in analysis and problemsolving skills, and to consolidate and expand the students39。主要目的是培養(yǎng)學(xué)生綜合運(yùn)用所學(xué)的知識(shí)與技能分析與解決問題的能力，并鞏固和擴(kuò)大學(xué)生的課堂知識(shí)。其中重點(diǎn)在水輪機(jī)發(fā)電機(jī)組選擇，主要包括機(jī)組臺(tái)數(shù)，單機(jī)容量及水輪機(jī)型號(hào)的選擇，水輪機(jī)尺寸的確定，蝸殼形式、包角、進(jìn)口尺寸的選擇，尾水管形式及尺寸選擇，相應(yīng)發(fā)電機(jī)型號(hào)、尺寸、調(diào)速器及油壓裝置的選擇。華北水利水電學(xué)院畢業(yè)設(shè)計(jì)目 錄中文摘要 .......................................................................I英文摘要 ......................................................................II第 1 章 基本資料 ................................................................1 任務(wù)的提出 ...............................................................1 工程地質(zhì)條件 .............................................................1 水庫區(qū)工程地質(zhì)條件 ...................................................1 壩址工程地質(zhì)條件 ......................................................1 引水隧洞和廠房區(qū)工程地質(zhì)條件 .........................................2 水文與氣象 ...............................................................3 流域自然地理概況 .....................................................3 水文資料 .............................................................3 水利、動(dòng)能及水庫 .........................................................6 電站任務(wù) .............................................................6 水庫水位 ..............................................................6 裝機(jī)容量的選擇 ........................................................6 引水隧洞的洞徑選擇 ....................................................7第 2 章 水輪機(jī)選 型設(shè)計(jì) ..........................................................8 機(jī)組臺(tái)數(shù)與單機(jī)容量的選擇 .................................................8 機(jī)組臺(tái)數(shù)選擇 .........................................................8 機(jī)組單機(jī)容量選擇 ......................................................9 水輪機(jī)型號(hào)及裝置方式的選擇 ...............................................9 水輪機(jī)型號(hào)選擇 ........................................................9 裝置方式的選擇 ......................................................10 水輪機(jī)參數(shù)計(jì)算 ..........................................................10 水輪機(jī)蝸殼設(shè)計(jì) ..........................................................14 蝸殼形式的選擇 ......................................................15華北水利水電學(xué)院畢業(yè)設(shè)計(jì)ii 斷面形狀及包角的選擇 ................................................15 進(jìn)口斷面面積及尺寸的確定 .............................................15 中間斷面尺寸的確定 ...................................................17 FR??
