<p><P>PROBLEM TO BE SOLVED: To enable high efficiency operation in the whole operation range from a partial load to a rated output in an engine generation device. <P>SOLUTION: This is the engine generation device constituted of an engine 5, an AC exciter 3, a winding type induction generator 1, a control device 6, and an inverter device 4 driven by exciting power. The AC exciter 3 has a fixed exciting winding 31 to which power is supplied by the inverter device 4 and a rotating armature winding 32 provided at a rotor 2 driven by the engine 4. The winding type induction generator 1 has a rotor winding 12 provided at the rotor 2 and a fixed armature winding 11. AC output of the rotating armature winding 32 provided at the rotor 2 is directly inputted into the rotor winding 12, and the control device 6 controls the rotational speed of the engine 5 at such a speed that high engine efficiency can be obtained according to an output required for the generation device. A gap between an output frequency F of the winding type induction generator 1 and a rotational frequency of the rotor 2 controls the frequency of the exciting winding 31 so as to be a frequency f2 of an AC output of the rotating armature winding 32. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
