广州抽水蓄能电站是我国正在兴建的第一座大型抽水蓄能电站,该电站第一期工程装机容量为120×10~4kW,第二期工程总装机容量为240×10~4kW.由于该电站分为两期施工,两期工程的水库的正常蓄水位不同,故与该电站配套工程的上库溢洪道也分为两期施工.在上库溢洪道二期工程的水工模型试验中,溢流堰采用了一种新型的消能工——阶梯溢流堰,本文介绍其试验研究成果.
Guangzhou Pumped Storage Power Station is the first large-scale pumped storage power station under construction in our country. The installed capacity of the first phase of this power station is 120 × 10 ~ 4kW and the total installed capacity of the second phase is 240 × 10 ~ 4kW. The power station is divided into two phases of construction, two phases of the reservoir’s normal water level is different, so the upper reservoir spillway supporting the project is also divided into two phases of construction.In the upper reservoir spillway of the second phase of the hydraulic model test, Overflow weir uses a new type of energy dissipater - step overflow weir, this article describes its experimental research results.
