The protection of shunt capacitor bank includes: a) protection against internal bank faults and faults that occur inside the capacitor unit; and, b) protection of the bank against system disturbances. Section 2 of the paper describes the capacitor unit and how they are connected for different bank configurations.
Relay protection of shunt capacitor banks requires some knowledge of the capabilities and limitations of the capacitor unit and associated electrical equipment including: individual capacitor unit, bank switching devices, fuses, voltage and current sensing devices.
CONCLUSION The many variations in capacitor bank design mean there is no one-size-fits-all solution to bank protection. The basic concepts of short-circuit protection and element failure detection remain unchanged, regardless of bank design. We recognize that different protection types are useful for different conditions.
The unbalance protection should coordinate with the individual capacitor unit fuses so that the fuses operate to isolate the faulty capacitor unit before the protection trips the whole bank. The alarm level is selected according to the first blown fuse giving an early warning of a potential bank failure.
In addition to the relay functions described above the capacitor banks needs to be protected against short circuits and earth faults. This is done with an ordinary two- or three-phase short circuit protection combined with an earth overcurrent relay. Reference // Protection Application Handbook by ABB
The objective of the capacitor bank protection is to alarm on the failure of some minimum number of elements or units and trip on some higher number of failures. It is, of course, desirable to detect any element failure. II. ELEMENT AND UNIT FAILURES EXAMINED
