Abstract: The author reports on an economic surge tank design for of the hydraulic system of high-head, peak-load storage power plants. The operation of storage power plants requires a completely free operation without any restrictions on changes in loading or flow of neither the pumps nor the turbines. Examinations of traditional, simple shaftor chamber-type surge tanks show their ineffectiveness due to the required chamber volume and the resulting costs. This demand led to the development of a more effective throttling device in connection with dual chamber surge tanks. Several surge tanks with this sophisticated system of the so-called reverse-flow throttle are already under operation in Austria.
