Taking into account that the 5th harmonic exceeds the limit, the reactance rate of 5 % should be used. The parallel capacitor reactance rate of a capacitor has great influence on switching inrush current, harmonic suppression, a capacitor’ effective capacity and the capacitor’s insulation requirements.
It can be seen that the voltage at the end of the capacitor increases with the increase of the reactance rate, and then the insulation requirements of the capacitor are also improved. The voltage of a capacitor which has the series reactor will be increased, and the amplitude of the increase is related to the percent of the series reactor.
Generally it is a very good remedy for harmonic suppression to string a reactor in the capacitor. So, analyzing the reactance rate of the parallel capacitor is very important. The parallel capacitor provides reactive power compensation to ensure the stability of the system’s voltage.
When there are harmonic sources in a system, a parallel capacitor will enlarge the harmonics, producing harmonic resonance. Since it is an effective strategy to install a suitable reactance rate of reactor into the capacitor to restrain the harmonics, further analysis is necessary on the choice of reactance rate.
In order to limit the inrush current of capacitor, a reactance rate can be selected from 0.1 to 1 %. Because of the reactance rate is high, the capacitor insulation requirements are also higher, and the effective capacity of capacitor will decrease, so the low reactance rate is selected to suppress the inrush current.
Taking into account that the 5th harmonic does not exceed the standard, the reactance rate of 4.5–5 % is considered. Considering the capacitor insulation requirements and capacitors’ effective capacity, the reactance rate of 4.5 % should be used. 3.
