REACTIVE POWER COMPENSATION
Reactive Power can best be described as the quantity of "unused" power that is developed by reactive segments, for example, inductors or capacitors in an AC circuit or system. In a DC circuit, the result of "volts x amps" gives the power consumed in watts by the circuit. In any case, while this formula is additionally valid for absolutely resistive AC circuits, the circumstance is marginally more complex in an AC circuits containing reactive components as this volt-amp product can change with frequency.
In an AC circuit, the result of voltage and current is expressed as volt-amperes (VA) or kilo volt-amperes (kVA) and is known as Apparent power, symbol S. In a non- inductive purely resistive circuit, for example,

In a non-inductive resistive AC circuit, the active power will be equivalent to the apparent power as the part of P/S gets to be equivalent to one or unity. A circuits power factor can be expressed either as a decimal value or as a percentage.
Be that as it may, and in addition the active and apparent powers in AC circuits, there is additionally another power component that is available at whatever point there is a phase angle. This part is called Reactive Power (some times refered to as imaginary power) and is expressed in a unit called "volt-amperes reactive", (VAr), symbol Q and is given by the mathematical statement: VI. SinΦ.
Reactive power, or VAr, is not by any stretch of the really power at all represents the product of volts and amperes that are out-of-phase with one another. The measure of reactive power present in an AC circuit will depend up on the phase shift or phase angle between the voltage and the current and simply like active power, reactive power is positive when it is "supplied" and negative when it is

This representation is called a power triangle as shown This representation is known as a Power Triangle as indicated From the above power triangle we can see that AC circuits supply or devour two kinds of power: active power and reactive power. Additionally, active power is never negative, while reactive power can be either positive or negative in value so it is constantly profitable to reduce reactive power in order to enhance system
