The invention relates to power networks, and in particular to a battery energy source arrangement and voltage source converter system in such network. The battery energy source arrangement includes battery energy storage, having one or more parallel-connected battery strings and a mechanism for connecting a voltage of the battery strings to a load. The battery energy source arrangement further includes battery string voltage adapter devices connected in series with respective ones of the one or more battery strings wherein the battery string voltage adapter devices are designed to handle only a fraction of the voltage handled by the battery strings.

Battery energy source arrangement and voltage source converter system

A battery unit arrangement for high voltage applications. The battery unit arrangement includes a battery unit having a battery chassis, and a switching device. The switching device includes switching mechanism for switching the battery chassis between two positions, a first position connecting the battery chassis to a pole of the battery unitand a second position connecting the battery chassis to a zero potential. The invention also relates to a connection and disconnection arrangement and methods for operating such connection and disconnection arrangement.
