Alternator-motor and synchronous compensator
Hydraulic alternators and compensators

As the proportion of energy supplied by nuclear power plants increases, energy transfer stations are being developed, as these plants are not yet able to cope with rapid variations in load. It is therefore up to the energy transfer stations to consume the surplus energy during off-peak hours and to restore it (with losses) during peak hours. Of the various solutions envisaged (gas compression storage, superconducting coils, etc.), water pumping remains...
