In AC circuits, the power factor arises because inductive or capacitive elements are introduced into the circuit. Then it exists in the form of active power, reactive power, apparent power and so on. The simple understanding of reactive power is the energy exchange between the power supply and the load or the load and the load.
In sinusoidal AC current circuit, there are three kinds of power, active power, reactive power and apparent power. Active power; The amount of power a load can get. Reactive power; The amount of power that is reduced by transferring the output power of the power supply to the load. Apparent power; The output power of the power supply.
Whether reactive power is produced depends on the nature of the load, if: there are inductors and capacitors in the load, in these components it needs to consume power to store energy, capacitors store electrical energy, inductors store magnetic field energy, but these energies are not really consumed, just stored through different forms, so it is part of the energy called reactive power.
Reactive power generation; In an AC circuit, the load is not a pure resistive load, so the load cannot fully obtain the power output, but there must be a power reduction. This reduced power is used for the energy exchange of inductive or capacitive loads. However, reducing this part of the power is actually not consumed, but only the energy exchange between the power supply and the inductive load or the capacitive load. Therefore, the power that reduces this part of the energy exchange without consumption is called reactive power.
Reactive power is a special phenomenon in alternating current systems. The essence of reactive power is the power existing in electric and magnetic fields in various devices of AC circuits, which is the basic condition for the normal operation of many electrical equipment.
Noker Electric Svg static var generator is a very ideal reactive power compensation equipment, can be set to compensate the system harmonic, reactive power, three-phase imbalance, widely used in power electronic systems.
