Capacitor banks provide reactive power compensation by introducing capacitive reactive power into the system, which is especially useful for counteracting the inductive reactive power typically drawn by motors and transformers. Capacitors store electrical energy in the electric field created between their plates when a voltage is applied.

Since capacitors have a leading power factor, and reactive power is not a constant power, designing a capacitor bank must consider different reactive power needs. For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR. The

Reactive power compensation capacitors must be checked regularly. The regular checking of the capacitors makes it possible to detect their capacity decline below the permissible value, which may be caused by the passage of time [11].

Reactive power compensation systems work by dynamically adjusting the amount of reactive power in an electrical system to optimize performance, enhance power quality, and maintain voltage stability. The working principles vary depending on the type of technology used, but the core aim remains the same: managing reactive power to meet the needs of the power system
Such reactive power compensation devices are: The passive reactive power compensation includes the capacitor bank installation for reactive power injection. The active reactive power compensation consists of the use of flexible AC transmission system (FACTS) devices to change the reactive power and active power requirement.
Considering power capacitor with rated power of 20 kvar and rated voltage of 440V supplied by mains at Un=400V. This type of calculation is true, if there is no reactor connected in series with capacitor. Once we know the total reactive power of the capacitors, we can choose series of capacitors for PF correction.

The main purpose is to decrease the voltage fluctuation at a given terminal of transmission line. Therefore the reactive power compensation improves the stability of AC system. What is Reactive power?
Q – rated power of the capacitor at rated mains voltage. Not only capacitors should be protected against short circuit, but the whole capacitor bank as well. Usually, in the switchgear from which the CB is supplied, there is an additional circuit breaker for the capacitor bank. Its value should be selected as:
The generated KVAR of the capacitor bank is given by Reactive power, Qc = (Q1 − Q2) = [P × tan (∅1) − P × tan (∅2)] = P [tan (∅1) − tan (∅2)] As we get the required compensation value of reactive power provided by the capacitor bank then we can find out the capacitance of that bank. ‘Xc’ is the Impedance offered by the capacitor.
