Abstract (en)
The invention relates to a redundant system for operating spillway gates in a dam (1). The spillway gates (2) are provided by hydraulic cylinders (3) connected through a hydraulic circuit to a pump (17) arranged to feed hydraulic fluid through hydraulic pipelines from a tank (19) to the hydraulic cylinders (3) of the spillway gates (2) to open said spillway gates (2) when necessary. The hydraulic pump (17) is mechanically connected to a water turbine (15) to which water from the dam (1) is arranged to be fed when the water level (W) behind the dam (1) rises above an accepted level. The water flowing to the turbine (15) starts to rotate said turbine (15) and therewith the hydraulic pump (17) feeding the hydraulic cylinders (3) with hydraulic pressure to lift and open the spillway gates (2).
