Method for controlling power generation
First Claim
1. A method for controlling power generation with a generator in which a permanent magnet rotor (1) and a Randell rotor (1A) provided in a casing (20) are rotated simultaneously and generate power in an armature coil (5), said method comprising a first step of controlling a magnetic flux φ
- 2 of a control field coil (16a) for said Randell rotor (1A) with a field controller (48) during low speed rotation in an additive direction to add said magnetic flux φ
2 to a magnetic flux φ
1 produced by said permanent magnet rotor (1), and a second step of controlling said magnetic flux φ
2 during high speed rotation in a subtractive direction to subtract said magnetic flux φ
2 from said magnetic flux φ
1, such that a stable output level is produced.

Abstract
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 φ2 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 φ2 to a magnetic flux φ1 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 φ2 from the magnetic flux φ1, so that a stable output level is produced.
