It is reasonable to generate reactive power at the place where the reactive power is needed, i.e. to add reactive power compensation equipment and devices. The basic principle of capacitance compensation is as follows: in a practical power system, most of the load is an asynchronous motor. The equivalent circuit can be regarded as a series circuit of a resistor and an inductor, the phase difference between the voltage and the current is large, and the power factor is low. After the capacitors are connected in parallel, the current of the capacitors can offset a part of the inductive current, so that the inductive current is reduced, the total current is reduced, the phase difference between the voltage and the current is reduced, and the power factor is improved. The capacitance compensation cabinet plays a role of capacitance compensation.
