EXPERIMENTAL RESEARCH OF ELRECTROMAGNETIC COMPATABILITY OF GANTRY CRANE THYRISTOR VOLTAGE CONVERTER ELECTRIC DRIVE AND SUPPLY MAINS

Abstract

On the basis of the conducted experimental researches a total harmonic distortion of supply mains voltage is estimated during the starting and braking transient processes of gantry crane electric drive fulfilled as a thyristor voltage converter and asynchronous motor. The correlation of supply mains and drive motors nominal currents is determined as well, by descent of which violation of electric power quality norms is possible. It was also set the possible number of gantry crane work cycles in accordance with electric power quality norms during twenty-four hours.
