Installation and Method For Supplying Power To A Subordinate Network Area

An installation for the supply of electricity to a subordinate network area is disclosed having a first connection to a superordinate network area which can be selectively established and disconnected by a disconnecting switch, a second connection to the subordinate network area, a high-voltage storage battery with charging electronics, a first conditioning device with an inverter for conditioning electrical energy from the high-voltage storage battery, a high-voltage distributor which is conductively connected to the high-voltage storage battery and the first conditioning device for the exchange of electrical energy, a synchronization controller coupled to a measuring probe in the superordinate network area for receiving measuring signals, and a controller for controlling at least the disconnecting switch, the high-voltage distributor and the first processing device. The first conditioning device can be controlled on the basis of the measurement signals received from the measuring probe.
