This is the process “reactive power compensation”. In most cases, the compensation is capacitive. A system may use capacitors in parallel (shunt) to line, or it may be in series, incorporated in the transmission line circuit. Depending on application, the compensation may be done using passive devices, active electronic circuits or

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.
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.
The capacitor bank was to be power capacitor based with automatic control by power factor regulator. This type of device was chosen as a compensator, because of its price compared i.e. to active filters.
Generally, we can assume that the power loss of the power capacitor (including wires, discharging resistor and contactors) is approximately 7W per / kvar – for acceptor circuit (capacitor and reactor). According to the formula: Where: Taking into account the rules above, following cubicle was selected: Table 2 – Enclosure dimensions
This phenomenon will occur when the CT is installed at load side or inside the capacitor cabinet. If only load current is sampled, the power factor will remain almost the same after connecting capacitors manually; if only cabinet current is sampled, the power factor will decrease after connecting capacitors manually.
