Title:
NATURAL FREQUENCY REGULATING METHOD FOR SYNCHRONOUS MACHINE
Document Type and Number:
Japanese Patent JPH0556700
Kind Code:
A
Abstract:
PURPOSE: To lower natural frequency without increasing the inertial moment of generator motor.
CONSTITUTION: In a synchronous machine operating in parallel with a power system, state variables such as variation of electrical angle Δω, variation of angular speed Δω variation of field flux Δrd and variation of field voltage ΔErd are applied, with feedback coefficients of F1, F2, F3, F4, onto an exciting system and then a control circuit regulates the natural frequency and damping ratio of the synchronous machine.
