【摘要】：為研究通倉型進(jìn)水口水力特性,探討水電站最佳運(yùn)行方案,結(jié)合某實(shí)際工程,建立了全三維水動(dòng)力數(shù)學(xué)模型,并同步開展了大比尺物理模型實(shí)驗(yàn),計(jì)算結(jié)果與實(shí)驗(yàn)結(jié)果進(jìn)行了相互驗(yàn)證。對不同運(yùn)行工況下通倉型進(jìn)水口流速及水頭損失等開展研究,結(jié)果表明:疊梁門頂流速分布受機(jī)組運(yùn)行影響顯著;與常規(guī)分層取水進(jìn)水口相比,最大過柵流速降幅可達(dá)60%以上;分層取水進(jìn)水口采用通倉型布置,其水頭損失最大降幅達(dá)到50%左右。從水力特性出發(fā),采用通倉型進(jìn)水結(jié)構(gòu)是降低進(jìn)水口過柵流速,減小水頭損失的有效辦法,同時(shí)建議采用對稱原則確定運(yùn)行方案。
[Abstract]:In order to study the hydraulic characteristics of the water inlet and discuss the optimal operation scheme of the hydropower station, a full three-dimensional hydrodynamic mathematical model was established in combination with a practical project, and a large scale physical model experiment was carried out simultaneously. The calculated results are verified with the experimental results. The velocity and head loss of the silo type inlet under different operating conditions are studied. The results show that the velocity distribution at the top of the laminated gate is significantly affected by the operation of the unit, and the maximum velocity over the gate can be reduced by more than 60% compared with the conventional stratified intake. The delamination intake adopts the silo type arrangement, and its water head loss decreases by about 50%. Based on the hydraulic characteristics, adopting the silo type inlet structure is an effective method to reduce the flow velocity and the head loss at the inlet. At the same time, it is suggested that the operation scheme should be determined by the principle of symmetry.
