                **HOW TO COMPENSATE THE REACTIVE POWER**

In an AC circuit the reactive power can be described as the unused power by the reactive components it is a consequence of AC system it is used to build up magnetic fields. Reactive power compensation is to manage the reactive power in order to improve the performance of the alternating current power systems. Reactive power compensation in transmission system will improve the stability of the AC system by increasing the active power
By maintaining a proper reactive power we could regulate the power factor of the system and also stability of the voltage could be done too, the reactive power is created by the inductive and capacitive loads

REQUIREMENTS OF REACTIVE POWER IN POWER SYSTEM

• To supply active power we need proper voltage reactive power will provide the voltage levels which is needed for transmission it is also used to move the active power through transmission and distribution system
• Prevention of damage in power system could be done by reactive power by providing voltage control
• Reactive power is directly proportional to the voltage level so if reactive power is more voltage level would be high
• It could avoid blackouts by giving proper voltage
• Varying reactive power will vary voltage level
• Induction motor requires reactive power
• Reactive power is needed to generate magnetic flux
• The magnetization of the core is not possible without reactive power
• Reactive power is absorbed by components like motor and inductor
• Larger and smaller loads require reactive power
• It will improve the efficiency of power delivery
• Reduces congestion
• Grid reliability and stability

REACTIVE POWER COMPENSATION

Shunt compensation of the reactive power could be done either at load, substation or transmission level the compensation must be provided close to the consumption to avoid the distribution in other parts

By using shunt capacitors
• Reduction of the line current is done
• Improves voltage level
• Reduces system losses
• Reduces the load of the alternator
These benefits are created by using the shunt capacitor to adjust the reactive power
