VOLTAGE CONTROL METHOD FOR INDUCTION GENERATOR USING VARIABLE REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a voltage control method which can extend an upper limit of an operation speed range of a self-excitation induction generator to a value three times that of a conventional technology. SOLUTION: This voltage control method for a self-excitation induction generator changes an inductance by a variable reactor to change a value of an equivalent capacitive current so as to correspond to a revolution of the self-excitation induction generator and a load variation.
