Capacitor Bank: Definition, Uses and Benefits
Nowadays, reactive power compensation is one of the most important problems in the radial distribution networks. For this reason, the employment of shunt capacitors is recommended for improvement of the voltage profile, reduction of total power losses, increasing the power transmission line capacity, power factor improvement, etc.
A shunt capacitor is extensively used to transmit reactive power to loads in the main distribution. These capacitors supply an economical reactive power to meet up reactive power necessities for different loads. The …
Series compensation also improves the voltage profile along the power corridor and optimizes power sharing between parallel circuits. Series compensation technology Because series capacitors are installed in series on a transmission line, the equipment must be elevated on a platform at system voltage, fully insulated from ground .
For decades, fixed series compensation is the proven solution to maintain a minimum voltage profile and maximize utilization of transmission lines. It works by connecting a capacitor bank in series with the transmission line to partially compensate the inductive impedance of the line while also increasing the voltage at the point of connection.
