Abstract

The present application discloses a voltage drop compensation method and a voltage drop compensation device for a DC power line. The voltage drop compensation method or the voltage drop compensation device can perform more accurate corresponding compensation for the voltage drop of a DC power line through manual pressure difference compensation parameters. , when the user forgets to set the manual voltage drop compensation parameter, the automatic voltage drop compensation parameter can also be used to perform more accurate automatic compensation for the voltage drop of the DC power line; through double compensation measures, a more accurate voltage drop compensation can be selected, not selected For more accurate voltage drop compensation, it is also possible to perform more accurate automatic compensation for the voltage drop of the DC power line to ensure corresponding compensation for the voltage drop of the DC power line.

Description

technical field [0001] The present application relates to the technical field of DC power line voltage drop compensation, in particular to a voltage drop compensation method and a voltage drop compensation device for a DC power line. Background technique [0002] In order to meet the application requirements of more abundant scenarios, the length of the power extension cord is also continuously extended as a part of the power cord. The longer the length of the power extension cord, the greater the resistance value of the power extension cord, and the difference between the input voltage of the power cord and the output voltage of the power cord will also increase; especially when the current transmitted by the power cord is high , it will further increase the difference between the input voltage of the power line and the output voltage of the power line. [0003] However, the output voltage of the power line is used to provide power for the device. When the above-mentioned ...
