The supply device has a variable rotation rate motor-generator (4) mechanically coupled to a mass (5) for storage of kinetic energy, used for providing electrical energy upon failure of the mains network (10). A stand-by drive (6), e.g. a diesel engine, is coupled to a second electrical generator (7), which also operates as a motor and which is permanently coupled to the supplied network (1,2,3) for delivering the blind current. |
