When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors'' capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors. As we''ve just seen, an increase in
In either case, adding a parallel capacitor, whose value is equal to the inductive load, drops the source''s current output to just the, in phase, value needed for the resistive load. Too Little, Too Much and Just Right. Interestingly enough, "compensation" is an EXACT science, in the sense that," too little" is, actually, the same as "too much". Remember that the inductive

Fig. 3 shows the equivalent circuit of one stator coil, a parallel capacitor and a load. The stator coil equivalent circuit consists of induced voltage, coil resistance and coil inductance.
The voltage on primary parallel compensation capacitor rises to source voltage instantaneously when the voltage polarity changes, causing instant large current and impairing capacitor lifespan.

This solution is not feasible, since the amount of the grid impedance, thus its resonance frequency, varies depending on the operating conditions of the power system. The application of parallel compensation instead of series compensation is possible as well. But the parallel capacitors may cause super-synchronous resonances .
