System for stabilising a power supply network

摘要

The stabilising system for use with an electrical power supply network Ä10Ü has an inductance Ä12Ü coupled to a converter Ä22Ü that has AC windings Ä24,26Ü, a rotor Ä28Ü and a DC excitation winding Ä30Ü. One of the windings connects with a converter circuit Ä40Ü coupled to a synchronous machine Ä52Ü and this has a flywheel Ä54Ü coupled to the rotor. This provides an energy storage unit that can be connected to the network to supply or draw power in a controlled way for stabilisation.
