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.
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.
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.
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.
Use of capacitive (shunt compensation) on various part of the power system improves power factor, Reduce power losses, improves voltage regulation and increased utilization of equipment. Reference: Electric power generation, Transmission and distribution by Leonard L.Grigsby. Power system supply or consumes both active and reactive power.
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.
