Such reactive power compensation devices are: The passive reactive power compensation includes the capacitor bank installation for reactive power injection. The active reactive power compensation consists of the use of flexible AC transmission system (FACTS) devices to change the reactive power and active power requirement.
The power factor of the system is therefore improved. In an installation consuming reactive power Q1 (Diagram 1), adding a capacitor bank generating a reactive compensation power Qc (Diagram 2) improves the overall efficiency of the installation.
Excellent. The aim of project called „Reactive power compensation panel” was to design capacitor bank with rated power of 200kVar and rated voltage of 400V adapted for operation with mains, where higher order harmonics are present. The capacitor bank was to be power capacitor based with automatic control by power factor regulator.
This article will shed some light on how adding capacitors gives the distribution system the necessary reactive power to return the power factor to the required level. Capacitors act as a source of reactive energy, which accordingly reduces the reactive power that the energy source must supply. The power factor of the system is therefore improved.
The generated KVAR of the capacitor bank is given by… Reactive power, Qc = (Q1 − Q2) = [P × tan (∅1) − P × tan (∅2)] = P [tan (∅1) − tan (∅2)] As we get the required compensation value of reactive power provided by the capacitor bank then we can find out the capacitance of that bank. ‘Xc’ is the Impedance offered by the capacitor.
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.
