Typically, an SVC comprises one or more banks of fixed or switched shunt capacitors or reactors, of which at least one bank is switched by thyristors. Elements which may be used to make an SVC typically include:
IEEE Std. 1036, “Guide for Application of Shunt Power Capacitors.” IEEE Std. C37.20.2, “Standard for Metal-Clad and Station Type Cubicle Switchgear.” IEEE Std. C57.16, “IEEE Standard Requirements, Terminology, and Test Code for Dry-Type Air-Core Series-Connected Reactors.”
Capacitor units mounted on poles usually range between 300 – 3000kVAR. EHV Shunt capacitor banks – Extra high voltage substations transmit power in bulk to load centers. When transmitting high-point loads of power, these lines tend to drop voltage significantly. As such, the EHV capacitors come into play when necessary, to create reactive power.
As mentioned above, shunt capacitors can be used in various locations, including electricity poles, substations, power transformers, EHV, and LV lines, among others. The application of shunt capacitors in utilities reduces the current flowing through the distribution feeder with the help of reactive power.
In general, the trend is toward larger unit sizes. Standard capacitor units for shunt capacitor bank applications are 50, 100, 150, 200, 300, and 400 kVAR. No upper limits are defined for internally fused capacitor units.
