Abstract
PURPOSE:To permit the detection of generation of axial torsion in a high speed, by a method wherein the magnitudes of phase differences in the frequency components of axial torsions of the change of angular velocity and the change of an electric torque are compared. CONSTITUTION:A signal, equivalent to the electric torque of a generator 2, is detected by a detecting circuit 73. Another signal, equivalent to the angular velocity of the generator 2, is detected by another detecting circuit 75. These signals are passed through band-pass filters 74, 76 to extract the axial torsion frequency components of these signals. These axial torsion frequency components are inputted into a phase difference comparing circuit 77 to detect phase differences while the generation or non-generation of the axial torsions due to an interference between the generator 2 and a DC transmission system 5 is decided by the magnitudes of the detected values. According to this method, the generation of the axial torsion may be detected in a high speed whereby the axial torsion may be restrained in an early period.
