Stator, especially of a twin-pole separately-excited synchronous machine, has structured coil systems to continue operating if a coil system fails

摘要

The stator (27), of a dynamo electrical machine with a power output of = 100 MW, has independent and insulated coil systems. Each coil system has three phases (U,V,W). Two coil systems form a pair with an electrical offset of 0[deg] in the phases and electrical offset of 30[deg] between the two pairs. Each coil system has its own current supply, with a current intermediate circuit converter (25) as the current supply system.
