Combined automatic capacitor banks, 60 Hz

Description

The combined reactive power compensation banks of the OPTIM SVGm range consist of a combination of a static reactive power generator, SVGm, and a set of steps of rejection filters tuned to 227 Hz (p = 7%), operated by a contact and controlled by a Computer SMART III power factor regulator.
The use of both technologies in a single compensation unit yields accurate reactive power compensation, with a high capacity to react to power changes that require compensation that represent a percentage of the device's total power, while providing a high cost to effectiveness ratio, all in a smaller size than the model consisting solely of regulated capacitor steps.
Similarly, the use of a SVGm as a supplement to the contactor-operated steps also provides capacitive power compensation, which is increasingly in demand, and it reduces problems related to the compensation of reactive power in installations containing a self-supply photovoltaic system.

Applications

The combined reactive power compensation banks of the OPTIM SVGm range are suitable for reactive power compensation in any installation where the use of rejection filters is required due to the presence of harmonics in the network, but especially in those where, due to the compensation requirements, using a conventional capacitor bank based on steps operated by contactors does not guarantee proper power factor correction that rules out the possibility of being penalized for excess reactive power consumption.
Installations where part of the total power of the compensation device has to respond quickly.
Installations where the addition of a self-supply system based on photovoltaics varies the demand for active power from the network such that a bank with steps does not cover the compensation needs, or those where at certain times, there is excess capacitive power, which is also subject to penalization.
