Identification of parameters of power line supplying excavator in career

Abstract

The paper considers the method for measurement of active and inductive resistances of the power line supplying career excavators based on mathematical processing of current and voltage at the input of the excavator in two modes of operation — power consumption and power recuperation during the excavation cycle. Parameters of measurement errors when using the line transducers of different class index numbers have been estimated. The effectiveness of the method has been confirmed by simulation of an excavator electrical system practical use of the developed module for controlling parameters of power line as a part of the information-diagnostic system designed for career excavators.
