Most of the load types in the power system are inductive loads. In addition, power users generally use power electronic equipment widely, which makes the power factor of the power grid low. Lower power factor reduces equipment utilization, increases power supply investment, damages voltage quality, reduces equipment service life, and greatly increases line loss. Therefore, by connecting the capacitance compensation cabinet in the power system, the inductive load can be balanced, the power factor can be improved, and the utilization rate of the equipment can be improved.
