【摘要】：古爾圖河位于東經(jīng)83°40′～83°53′北緯44°10′～44°51′之間。古爾圖河源頭位于北天山中部的博羅克努山東段，源頭山脊海拔高程一般在4000rn左右。是一條以冰川融水補給為主的河流。該河流多年平均徑流10.9m3/s，多年平均徑流量3.443億m3。 從海拔1000的出山口至烏伊公路附近高干閘段，河長25.5km，河道落差405m。河道在山前傾斜平原區(qū)的洪積扇上部，地面縱坡較緩，流經(jīng)礫石戈壁地區(qū)，河道滲漏損失較大，沖刷切割能力較差，河床變?yōu)閷挏\式的。 古爾圖河已建的水利工程有古爾圖河新、老渠首和古爾圖河引水干渠。古爾圖河新、老渠首均建有曲線沉沙池、泄洪閘和引水閘。古爾圖河干渠引水流量45m3/s年均輸水量3.04億m3，保證下游灌區(qū)50萬畝耕地的灌溉用水；該干渠由古爾圖河新渠首開始，全長25km，經(jīng)過老渠首至高干閘，然后通過高干閘由柳干渠和高干渠向灌區(qū)輸水。 本次工程擬建的古爾圖河五級電站是接古爾圖河四級發(fā)電后的尾水進行發(fā)電，再將尾水投入六級電站發(fā)電。引水渠設(shè)計流量按20.0m3/s確定，計入損失流量和沖沙流量后，發(fā)電流量按19.02m3/s確定。五級電站設(shè)計設(shè)計凈水頭52.03rn，經(jīng)計算其主要動能指標如下：裝機容量8.2MW，，保證出力1.39MW，多年平均發(fā)電量3194萬kW·h，裝機年利用小時3896h。 本文的主要工作： （1）查閱、收集、整理古爾圖河水文、工程地質(zhì)及水能的相關(guān)資料； （2）依據(jù)相關(guān)數(shù)據(jù)確定電站裝機容量、工程選址、工程布置等方案； （3）進行方案對比確定最優(yōu)方案； （4）經(jīng)濟分析該項目的可行性。
[Abstract]:The Gultu River is situated between longitude 83 擄40 and 83 擄53'N at 44 擄10'N and 44 擄51'N. The source of the Gultu River is located in the central part of the North Tianshan Mountains, and the elevation of the source ridge is generally about 4000rn. It is a river mainly supplied by glacial melting water. The average annual runoff of the river is 10.9 m3 / s, and the annual average runoff is 344.3 million m3. The river is 25.5km long and the river drop is 405m from the outcoming pass of 1000 altitude to the section of Gaogan sluice near the Wuyi highway. In the upper part of the alluvial fan in the sloping plain area of the mountain front, the surface longitudinal slope is relatively gentle, and the channel leakage loss is larger, the scour cutting ability is poor, and the river bed becomes wide and shallow type through the gravel Gobi area. The water conservancy projects of the Gultu River include the new Gultu River, the old canal head and the main diversion channel of the Gultu River. New Gultu River, old canal head are built curve sand basin, flood sluice and diversion sluice. The average annual water delivery capacity of the Gultu River trunk canal 45m3/s is 304 million m3, which ensures irrigation water for 500000 mu of cultivated land in the downstream irrigation area, which begins at the new head of the Gultu River with a total length of 25 km and passes through the head of the old canal to the Gaogan sluice. Then through Gaogan sluice from willow trunk canal and high trunk canal to the irrigation area. The fifth stage power station of Guertuhe River proposed for this project is the tailings of the Goultuhe River to generate electricity, and the tailings will be put into the sixth stage power station to generate electricity. The design flow of the diversion canal is determined by 20.0m3/s, and the power generation flow is determined by 19.02m3/s after taking into account the loss flow and sediment flow. The main kinetic energy indexes of 52.03rnof the design water purification head of the fifth grade power station are as follows: the installed capacity is 8.2 MW, the guaranteed output capacity is 1.39 MW, the average annual generating capacity is 31.94 million kW / h, and the annual operating hours are 3896 h. The main work of this paper is as follows: (1) to consult, collect and sort out the relevant data of Gultu river water, engineering geology and hydraulic energy; (2) to determine the power station installed capacity, project location, engineering layout and so on according to the relevant data; (3) to compare and determine the optimal scheme; (4) to analyze the feasibility of the project.
