Abstract

The harmonics in power system will cause parallel and series resonance

amplify harmonic voltage and current and affect the safe operation of power system seriously. The high order harmonic generated in the main drive system of rolling mill in the metallurgical industry causes partial series resonance in power supply system to produce overvoltage and damages industrial control system unit. In this paper

the improvement scheme is proposed throughout the measurement and analysis of harmonic data of main drive and control system to eliminate the harmonic voltage to produce series resonance and to keep the power supply system and industrial equipment load safe and normal operation

improve the engineer’s awareness to the danger of the harmonics

to take care of optimization design system of power quality and to ensure the reliability and safety of power supply system of the enterprises.
