What does charging power mean?

Charging power usually refers to the charging power of the transmission line, also known as reactive power; when the line is too long, there will be capacitance to the ground; the reactive power generated by the capacitance current of the line to the ground is called The charging power of the line; the charging power of the line is proportional to the square of the capacitor current.

What does charging power mean?

Charging power usually refers to the charging power of the transmission line, also known as reactive power. When the line is too long, there will be capacitance to ground. The reactive power generated by the capacitance current of the line to ground is called the charging power of the line.

When the power line is no-load or lightly loaded, the voltage will be higher than the power supply voltage. Because there is capacitance between the wires and to the ground, the capacitance will generate charging power (capacitance) when the line has voltage, so when the power line is unloaded or lightly loaded, the voltage will be higher than the power supply voltage. The charging power of the line is proportional to the square of the capacitor current. It can be solved by using a parallel reactor to perform inductive reactive power compensation, that is, absorb the charging power, partially or fully compensate the capacitance of the line, and then reduce the voltage. The reactor is best installed at the end.
