It is required that the power factor be improved by a four – step capacitor bank. Reactive Power of each step of the capacitor bank is 50kVars. i. Calculate resonant frequency (in harmonic order) of the circuit at every step of the capacitor bank. ii. A measured harmonic content of the above circuit is given in Table-1 below.
But having too much reactive power flowing around in the network can cause excess heating (I 2 *R losses) and undesirable voltage drops and loss of power along the transmission lines. Power Factor Correction of Reactive Power. One way to avoid reactive power charges, is to install power factor correction capacitors.
Apart from four basic compensation topologies, several novel compensation topologies are proposed, such as S/SP (primary series, secondary series–parallel) [8, 9], LCL (inductor–capacitor–inductor) [10-12] and LCC (inductor–capacitor–capacitor) [13, 14]. S/SP compensation topology can be regarded as a combination of SS and SP.
Calculation Example: Capacitor banks are used to improve the power factor of an electrical system by providing reactive power compensation. The design of a capacitor bank involves determining the required reactive power for compensation, the number of capacitor banks required, and the size of each capacitor bank.

Shifting the parallel resonance frequency of the source and the capacitor to below the main frequencies of the harmonic currents that are causing interference
this reactive power, two capacitor banks are connected in parallel via externally monitored circuit breakers for each phase. A feedback loop is designed to automatically turn on the capacitor banks whenever there is an increase in the load current and a reduction in the power factor, as shown in Figure 4.
It can be achieved by connecting a capacitor in parallel with the load. The capacitive reactance of the capacitor will cancel out the inductive reactance of the load, resulting in a more balanced power factor. ...
