Abstract

Abstract: Taking the mobile load as an example, combined with the electric power acquisition parameters of the actual equipment, this paper analyzes the three-phase voltage unbalance problem of the equipment during the traction process of the power supply, and puts forward a method for eliminating the charge-source reverse order, it can guide the analysis and emergency treatment of power quality problems such as three-phase voltage unbalance of industrial-grade source load, and ensure the stability mobile industrial-grade load.

Key words: industrial grade source charge, transformer, power traction, power quality, three phase voltage imbalance
