本文介绍了位于奥地利阿尔陴斯山区的高水头、峰荷抽水蓄能电站的发展情况。抽水蓄能电站的运行要求一个完全自由的操作环境,它既不受负荷变化的影响也不受水泵工况及水轮机工况下水流变化的影响。对传统的简单圆筒式调压井或者双室式调压井的研究表明:因为其室容太大,造价太高而不宜直接采用。这就要求开发一种更为有效的节流装置并与双室调压井相连。在奥地利几座装有这种所谓回流式节流阀的现代化装置的调压井已经投入运行。

This article describes the development of a high-head, peak-load pumped storage power station in the mountainous Árgules, Austria. The operation of a pumped-storage plant requires a completely free operating environment that is neither affected by load changes nor influenced by pump conditions and changes in water flow under turbine conditions. The research on the traditional simple drum surge tank or double chamber surge tank shows that it is not suitable for direct use due to its large capacity and high cost. This requires the development of a more effective throttling device and connected to the dual chamber surge tank. Surge tanks in modern installations in Austria with this so-called recirculation choke have been put into operation.
