Introduction Shunt capacitor banks (SCBs) are widely used for reactive power compensation and bus voltage regulation , . The cost of an SCB is relatively low compared to the other shunt compensation devices, e.g., SVC and STATCOM and thus SCBs are extensively utilized in power networks .
Most of these shunt capacitor banks are ungrounded except for the 315kV level where all banks are grounded to reduce the insulation level of the shunt capacitor bank neutral and also to reduce the recovery voltage (RV) constraint on the circuit breaker of the shunt capacitor bank when opening.
During the switching of shunt capacitor banks, high magnitude and high frequency transients can occur [1, 5, 6, 7]. In earlier years, shunt capacitor banks have been more commonly installed at distribution and lower subtransmission levels. However, there has been a recent proliferation of new capacitor banks at transmission levels.
At the same time, the presence of shunt capacitor banks impose constraints on apparatus present in a substation [1,2]. Currently, no specific configuration of shunt capacitor bank is recommended, grounded and ungrounded shunt capacitor banks can exist on the same transmission system.
Contributing to voltage instability, shunt capacitor banks have an unstable falling output as voltage sags. Applying shunt compensation involves many considerations. There are many options both for mechanically switched devices and power electronic based devices. Synchronous condensers are also an option.
Medium voltage shunt capacitor banks (SCBs) are widely used for improving voltage profile and providing reactive power in electrical networks. Transient oscillations caused by SCBs, e.g., switching and self-excitation phenomena, may damage sensitive equipment in electrical networks.
