A series capacitor is a reactive power compensation device. Usually series capacitors are used in EHV lines of 330kV and above. Its main function is to improve the system voltage from the perspective of compensating reactance, so as to reduce the power loss and improve the stability of the system. differences between shunt capacitors and
Reactive Power Compensation. A low value of power factor requires large reactive power and this affects the voltage level. Hence in order to compensate for the reactive power, the power factor of the system must be improved. Thus, the methods for reactive power compensation are nothing but the methods by which poor power factors can be improved

Voltage Control Devices: Various voltage control devices such as capacitors and reactors can be strategically placed in the power system to generate or absorb reactive power. Capacitors inject reactive power into the system, raising the voltage, while reactors absorb reactive power, thereby lowering the voltage. These devices are controlled
Capacitor banks are systems that contain several capacitors used to store energy and generate reactive power. Capacitor banks might be connected in a delta connection or a star (wye) connection. Power capacitors are rated by the amount of reactive power they can generate. The rating used for the power of capacitors is KVAR.
In simplest terms, reactive compensation is addition of reactive power devices, whether capacitive or inductive, to get a specific output. The specific output could be greater transmission capacity, enhanced stability, better voltage profile as also improved power factor.

There is voltage drop across the line from point A to point B, equal to. V = V 1 – V 2 = i (R + jX). Or V 1 – V 2 ≈ i (jX) if R << X.. Z is the net impedance between points A and B from all sources (line self- and mutual inductances, capacitance to ground etc.). The drop V can be significant, and efforts are made to reduce this drop, or reduce the effect of reactance X as

APFC (Automatic Power Factor Correction) is thus installed to provide flexibility of switching between different capacitors based on the running load. For instance, consider a capacitor bank with
When reactive power devices, whether capacitive or inductive, are purposefully added to a power network in order to produce a specific outcome, this is referred to as compensation. It''s as simple as that. This could involve greater transmission capacity, enhanced stability performance, and enhanced voltage profiles as well as improved power
Therefore, the relationship between the voltage and current of a capacitor is exactly opposite to that of an inductor. Capacitors are used to compensate for the reactive
Series compensation involves inserting a capacitor or an inductor in series with a transmission line to improve its voltage transmission characteristics. By inserting reactive power in series with the transmission line, the impedance of the system is reduced, which improves the power transfer capability of the line. This is particularly useful for long transmission lines, as

Reactive power compensation offers a variety of benefits, including improving energy efficiency, reducing energy costs and increasing grid stability. In many countries, certain regulations on reactive power compensation are mandatory to ensure the quality and stability of the electricity grid.
Power capacitors are rated by the amount of reactive power they can generate. The rating used for the power of capacitors is KVAR. Since the SI unit for a capacitor is farad, an equation is used to convert from the capacitance in farad to equivalent reactive power in KVAR.
By using capacitors for compensation, the company can generate its own reactive power and thus reduce the load on the grid. Reactive power compensation offers a variety of benefits, including improving energy efficiency, reducing energy costs and increasing grid stability.
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 stepping of stages and their number is set according to how much reactive power changes in a system.
Instead of using capacitor banks, there is a different alternative to compensate the reactive power that is based on the use of synchronous compensators. These are synchronous machines that, operating with null active power, can behave either as variable capacitors or coils, by simply changing their excitation current .
