高水头电站泄水道消能型式选择

无调节径流式电站压力前池溢流堰后的泄水建筑物——泄水道,担负电站机组负荷波动时多余来水量的宣泄,泄水道的类型按所采取的工程措施大致可分为天然泄水道、人工泄水道和混合泄水道三种。高水头电站一般前池位置较高,泄水道落差通常与电站利用落差不相上下,其工程投资大小和安全性与其消能型式的选择密不可分,如何选择其消能型式并进行工程布置就成为高水头电站厂区枢纽工程设计的关键工作之一。

Selection of Energy Dissipation Type in High Water Head Power Station Spillway

Sluicing building behind non-regulating run-of-river power station pressure front pool weir - spillway is responsible for sluicing the excessive water during power station unit load fluctuation. The types of spillway can be mainly divided into natural spillway, manual spillway and mixed spillway according to the adopted project measures. High water head power station generally has higher front pool position. The height difference of spillway is generally consistent with the power station utilization height difference. Its project investment and safety are similar to the selection of energy dissipation mode. Selection of energy dissipation type and engineering arrangement belong to one of keys in high water head power station plant hinge project design.
