Abstract
An energy storage system includes a vessel, an energy conversion device, and a connection line connecting the vessel with the energy conversion device. The energy conversion device includes a housing, a pump turbine, and a motor generator. The pump turbine includes a first shaft, and an impeller. The motor generator includes a second shaft, and a rotor. The second shaft is coupled to the first shaft to transmit torque between the first shaft and the second shaft. The connection line connects a low pressure opening with an opening disposed at the vessel to receive water from the vessel or discharge water into the vessel. The connection line includes a switching unit with a shut-off device and a non-return device connected in parallel, the non-return device enabling flow of the water only in a first direction from the vessel to the low pressure opening.
