Title:
VARIABLE VELOCITY POWER GENERATING MOTOR CONTROL METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JP3395124
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To realize the harmonization of velocity control and effective power control of variable velocity power generating motor.
SOLUTION: An effective power exchanged between a power generating motor 3 and a power system 1 and a terminal voltage of the power generating motor 3 are respectively detected, frequency, phase and amplitude of an excitation current of a secondary coil of the power generating motor 3 are controlled based on deviation, in order to adjust these detected values to respective command value and detected value of the rotating velocity of the power generating motor 3 is adjusted to the command value. For compensation of control amount in relation to the effective power on the basis of the velocity deviation, the effective power is preferentially controlled when the detected value of the rotating velocity is in the preset range and the velocity is preferentially controlled when the detected value goes out of the preset range.
