The capacitor bank was to be power capacitor based with automatic control by power factor regulator. This type of device was chosen as a compensator, because of its price compared i.e. to active filters.
The OPTIM FR P&P Series capacitor banks with detuned filters have been designed for power compensation purposes in networks with fluctuating load levels, a high content of harmonics and where there is a risk of resonance. Power variations are relatively slow (in seconds) so that the switching operations are carried out with contactors.
EN 61921:2005 describes the general requirements for the capacitor bank. The most important of them are listed below: Index of protection depends of the place of the installation of a capacitor bank. If the capacitor bank is to be placed in the same place as the main switchgear or utility room next to it, IP 20 is enough.
Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.
Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors. For this reason, some calculations have to be performed, in order to fit the power of the capacitors and its rated voltage taking into account reactive power of a detuning reactors.
As an example, if it was found, that in the grid there are following harmonics: 5 th, 7 th, 11 th, 13 th the LC parameters has to be selected so that the resonance frequency is included in range 174 – 210Hz (usually 189Hz). This type of filtering is being used in the automatic capacitor banks.
