CALCULATION OF PARAMETERS OF PASSIVE FILTERS IN SHIP’S ELECTRIC DRIVES “THYRISTOR VOLTAGE CONVERTER–INDUCTION MOTOR”

Abstract

Proposed is a method of passive filters parameters calculation, which enables determining series oscillatory circuits RLC parameters for decreasing the ratio of harmonic distortions in ship’s network to the set level with the use of actual, obtained as a result of an experiment or calculation, values of voltage and current non-sinusoidal signals harmonic components amplitudes. The input oscillations damping ratio for a given part of period allows to obtain the filters RLC with the optimal mass-and-dimensions, technical and economical parameters.
