摘要： A magnetic armature wedge is provided for replacing conventional dovetail wedges in high-powered large-size turbine generators. The magnetic armature wedges that are used for supporting the armature bars are made by molding resin, e.g., epoxy with ferromagnetic particles, wires, laminates and the like embedded therewithin. The magnetic particles, wires, laminates and the like increase the magnetic permeability of the wedges causing higher slot flux leakage and high generator subtransient reactants.

摘要： A synchronous generator is disclosed having main power windings and auxiliary power windings, where the auxiliary power winding is coupled to a variable frequency drive system. The variable frequency drive causes the generator to function as a motor and turn a drive shaft to start a gas turbine. Switching circuits are used to connect and disconnect the auxiliary windings of the generator with the variable frequency power supply.

摘要： A polyphase electric generator (10) is disclosed having a fixed output voltage configurable to virtually any voltage level within a certain range of voltages. The armature winding (18) of the generator is arranged in a combined Delta and Wye topology (60, 66). Each phase winding (20, 54) in the armature is partitioned into first and second sections of the phase winding (56, 58). The first sections (56, 62, 64) of each of the phase windings are arranged together in a Delta topology (60). Each of the second sections of each phase winding is arranged in a Wye topology (66) with a pair of the first winding sections. Each of the second sections (58) are connected at one end to a node (68) of the Delta topology where two of the first winding sections are connected. The opposite ends (70) of the second sections of each phase winding are connected to output terminals (26) of the armature to provide a line-to-line voltage output. The line-to-line output voltage (30) of the generator is dependent on the voltage across each winding phase (24) and the proportion of each phase winding arranged in a Delta topology.
