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.
