Reactive compensation of transformers In order to operate correctly, a transformer requires internal reactive energy to magnetize its windings. the table opposite gives, for information purposes only, the value of the fixed capacitor bank to be installed according to the powers and loads of the transformer.
Shunt capacitors are commonly used in distribution system for reactive power compensation. Different analytical, numerical programming, heuristic and artificial intelligent based techniques have been proposed in the literature for optimum shunt capacitor bank (SCB) placement.
Compensation can be provided by a bank of capacitors. In transformers, reactive power is absorbed by both shunt (magnetizing) and series (leakage flux) reactances. Complete compensation can be provided by a bank of shunt-connected LV capacitors A simple illustration of this phenomenon is given by the vector diagram of Figure L21.
A large part of the installation is thus freed from the consumption of reactive power. As with any compensation, the important point is to eliminate the penalties for excessive consumption of reactive energy and increase the transformer's available active power.
The capacitor bank is connected upstream of the HV/lV transformer. The additional cost connected with high voltage insulation rules out any benefit of using this for low power compensation (apart from in the case of individual requirements).
