摘要： A rotating shaft is required to have an overhang for the mounting of a generator for an AC-exciter, the shaft length being increased correspondingly. The overhang may become the cause of generating shaft vibrations. A turbogenerator has a rotor over which a field winding is disposed, a coupling co-cut from a rotor shaft, an AC exciter for supplying a DC current to the field winding through a rectifier, and a generator for the AC-exciter, the generator including a permanent magnet as a field generator and supplying a DC current to a field winding of the AC exciter through the rectifier. The AC exciter and the generator are disposed over the rotor shaft. The rotor is rotated through engagement between a turbine and the coupling. The generator for the AC-exciter is mounted in a position on the side nearer to the turbine than a stator of the turbogenerator.

摘要： Because of the necessity of resolver for detecting a rotating position, which is very expensive, and noise suppression of the rotating position signal line on a doubly-fed machine, cost increase of the generator and reduced reliability due to possible failures are inevitable. In order to solve such problem, a generation system in the present invention is equipped with an exciter that estimates the slip frequency of the doubly-fed machine from each primary current I1 and voltage V1 and secondary current I2 and voltage V2 of the doubly-fed machine and excites the secondary of the doubly-fed machine at the estimated slip frequency.
