影响抽水蓄能电站进、出水口水流特性的主要因素之一是进口水流的波涡问题,故侧式进、出水口上方常采用矩形或百叶窗式斜染进行防涡.但就荒沟抽水蓄能电站上池而言,采用这种消涡措施,经试验测得进水目前平均流速达1.60m/s左右,在各级发电工况运行时,防涡梁上方均产生吸气漩涡.依此对原防涡方案进行了修改和研究,提出了阶梯立式防涡梁防涡和消涡方案,取得了较好的防涡和消涡效果,从而为防涡工程提供了一种新的措施.
One of the main factors affecting the water flow characteristics of the inlet and outlet of a pumped storage power station is the vortex of the inlet water flow. Therefore, a rectangular or blind-type oblique dyeing is commonly used above the side inlet and outlet to prevent vortexes. However, for Huanggou Pumped Storage Power Station, with this vortex elimination measure, the average current velocity of influent is about 1.60m / s, and when the power generation conditions at all levels operate, the top of the anti-vandal beam Have produced inspiratory vortex. Based on this, the original anti-vortex scheme was modified and studied, and the anti-vortex and anti-vortex scheme of the vertical anti-vortex beam ladder was put forward and the better anti-vortex and vortex elimination effects were obtained, thus providing a new The measure.
