Reactive compensation is a technique used in power engineering to balance the real and reactive power in a power system. It is achieved by introducing a capacitor or inductor in the system that can absorb or generate reactive power as needed.
Reactive compensation is typically used when the power system is operating at low power factor (PF), meaning that the power consumed by the system is less than the power produced by the generators. When the power factor is low, the generators are unable to produce the full amount of power that is needed by the load, resulting in power shortages.
To compensate for this, reactive compensation is used to absorb the reactive power that is being generated by the generators. This can be achieved by connecting a capacitor in series with the generators or by connecting an inductor in series with the generators.
The type of reactive compensation that is used in a power system will depend on the specific requirements of the system, such as the power rating of the generators, the load connected to the system, and the desired power factor.
For example, in a power system with a high-power-factor generator, a capacitor may be used to compensate for the reactive power that is generated by the generator. In a power system with a low-power-factor generator, an inductor may be used to compensate for the reactive power that is generated by the generator
