METHOD FOR CONTROL OF SYNCHRONOUS GENERATOR EXCITATION Russian patent published in 2013 - IPC H02P9/10 H02P9/12 

FIELD: electricity.

SUBSTANCE: in method for control of synchronous generator excitation amplification coefficients are set against derivative of excitation winding current, deviations and voltage derivatives of stator winding and generator frequency; excitation is measured and regulated against deviations of the specified values and their derivatives. During transient period pairs of training support vectors that consist of discreet samples of electric generator signals and discreet samples of these signals delayed per one sampling period; learning set is added with the above training support vectors and included N transient processes. Three-layer neuron net is taught with sequential presentation of pairs of training support vectors till minimum mean-root error of training is reached: against weight coefficients of trained neuron net by means of the preset multidimensional array amplification coefficients are determined with deviations and derivatives of voltage and frequency and amplification coefficient with current derivative of generator excitation winding; thereafter coefficients are averaged against N transient processes and set as regulating parameters where N is depth-averaging of regulating parameters.

EFFECT: decreasing scale and duration of transient processes, increasing rate of their breakage.
