After the capacitors are connected in parallel, the capacitors release capacitive reactive power, and the reactive power required by the load is no longer absorbed from the system, so the reactive power is reduced. The active power is constant, and the power factor =COS(ATAN(Q/P)). So as long as the compensation capacitor is not compensated too much, the power factor will definitely increase.

Not the bigger the better,

Because the reactive power demand in the system is in a relatively stable range, shunt capacitors are used to compensate the system, and reasonable compensation should be paid attention to. If the capacitance of the capacitor is too large, there will be overcompensation, which is more harmful to the system than insufficient compensation.

You can use vector diagram to analyze, think for yourself, this topic is available in universities, and teachers will also talk about it, because it is an experimental thinking problem, thank you!
