The k factor is read from a table 1 – Multipliers to determine capacitor kilovars required for power factor correction (see below) and multiplied by the effective power. The result is the required capacitive power. For an increase in the power factor from cosφ = 0.75 to cosφ = 0.95, from the table 1 we find a factor k = 0.55:
Depending on the size of a compensation unit, it is assembled with capacitors of equal size (in bigger units) or of different size. A unit with a total reactive power of, for example, 300 kvar consists of six power capacitors, of 50 kvar each. Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps.
Note: if you want to calculate the capacitor bank in VAR/MVAR means, just enter the real power in W or MW. Example, if you are entering it in kW mean, you get kVAR only. The same way work for W and MW.
Capacitor Bank calculator is used to find the required kVAR for improving power factor from low to high. Enter the current power factor, real power of the system/panel and power factor value to be improved on the system/panel. Then press the calculate button to get the required capacitor bank in kVAR.
Considering power capacitor with rated power of 20 kvar and rated voltage of 440V supplied by mains at Un=400V. This type of calculation is true, if there is no reactor connected in series with capacitor. Once we know the total reactive power of the capacitors, we can choose series of capacitors for PF correction.
Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors. For this reason, some calculations have to be performed, in order to fit the power of the capacitors and its rated voltage taking into account reactive power of a detuning reactors.
