Technical Field

Background
In a power distribution network of a power system, a public transformer user with the installation capacity within 100 kilovolt and not higher than 400 volts does not need reactive power control, an agricultural farmer and a small industrial user apply a large amount of three-phase motors, the power factor is low, the line loss of a low-voltage 400-volt distribution line is high, the power transmission capacity is reduced, the terminal voltage is low, and the most effective mode for treating the problems is to arrange a reactive power compensation device with corresponding capacity nearby at the user.
The traditional reactive compensation strategy for the power distribution network to the public low-voltage 400-volt power distribution network is to intensively configure reactive compensation devices at a low-voltage 400-volt bus (a power supply end) of a distribution transformer, and the reactive compensation strategy can improve the power factor and the voltage of the distribution transformer, but when the power consumption place of a user end is far away from the distribution transformer and the power factor is low, a large amount of reactive power is transmitted in a long distance on the low-voltage line, and the current for transmitting the same active power can be increased. The conventional reactive compensation strategy may have the following problems:
