Guidelines for protection of shunt capacitor banks can be found in IEEE C37.99. Capacitor banks are not intended to be applied where the maximum operating voltage exceeds the nominal voltage rating of the capacitor bank.
High voltage shunt capacitors are used on electric power networks at transmission and distribution levels. Capacitor banks are found at substations for power factor (PF) correction and voltage control. Shunt capacitors, properly sized and located, provide voltage regulation.
Abstract— High voltage shunt capacitor banks (SCB) are widely used on power systems. The installation of shunt capacitor banks has beneficial effects such as the voltage regulation and the reduction of the losses of active power to be transmitted.
The main disadvantage of SCB is that its reactive power output is proportional to the square of the voltage and consequently when the voltage is low and the system need them most, they are the least efficient. 2. THE CAPACITOR UNIT AND BANK CONFIGURATIONS The capacitor unit, Fig. 1, is the building block of a shunt capacitor bank.
The IEEE Std 18-1992 and Std 1036-1992 specify the standard ratings π of the capacitors designed for shunt connection to ac systems and also provide application guidelines.
Studies show that a flat voltage profile on the system can significantly reduce line losses. Shunt capacitor banks are relatively inexpensive and can be easily installed anywhere on the network. This paper reviews principles of shunt capacitor bank design for substation installation and basic protection techniques.
