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
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.
Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton’s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
Protection of shunt capacitor banks is described in references [8.10.1] to [8.10.5]. Shunt capacitor banks (SCBs) are widely used in transmission and distribution networks to produce reac-tive power support.
Abstract: Capacitor banks are applied in power systems to provide reactive power. The reactive power results in lower current in lines upstream of the bank improving system voltage and power factor and reducing line losses. Capacitor banks can be configured as filters for harmonic reduction.
When designing a capacitor bank, many factors must be taken into consideration: rated voltage, kvar needs, system protection and communications, footprint and more. These factors govern the selection of the capacitor units to be used, along with proper grouping of these units.
