Analysis on the Reason of Low Voltage Problem and the Effectiveness of Voltage Regulation in a Distribution Area

Abstract For the problem of low voltage, this paper took a 10kV low voltage line as the research object, summarized and classified the causes of low voltage on the line, analyzed the real reason for the problem of low voltage which combined with the actual situation of the line as the class, put forward many management suggestions. Combined with the actual situation of the line, line automatic voltage regulator would be installed. For automatic voltage regulator, its effectiveness was analyzed from the principle in this paper, 10kV line simulation model was established, this paper gave the simulation analysis of the effect of the line overload on the terminal user’s voltage and the different control effects brought by the installation location of the voltage regulator, the research results provide a scientific basis for the management of the low voltage problem.
