Method for controlling power generation

摘要

The present invention is concerned with a method for power generation which may be used in conjunction with a generator in which a permanent magnet rotor and a Randell rotor provided in a casing are rotated simultaneously and generate power in an armature coil. The method includes a first step of controlling a magnetic flux phi 2 of a control field coil for the Randell rotor with a field controller during low speed rotation in an additive direction to add the magnetic flux phi 2 to a magnetic flux phi 1 produced by the permanent magnet rotor, and a second step of controlling the magnetic flux during high speed rotation in a subtractive direction to subtract the magnetic flux phi 2 from the magnetic flux phi 1, so that a stable output level is produced.
