Hesreko shows you what reactive power compensation is:

reactive power compensation is a technology that plays a role in improving the power factor of the power grid in the power supply system, reduces the loss of power supply transformers and walk lines, improves power supply efficiency and improves the power supply environment.

To understand reactive power compensation, we must first understand several concepts, "active power" and "reactive power" and "power factor"

1. active power

directly consumes electrical energy, converts electrical energy into mechanical energy, thermal energy, chemical energy or sound energy, and applies these energies to do work, this local power is called active power

2. reactive power

reactive power, many electrical equipment are relying on the establishment of alternating magnetic field to stop energy conversion and transmission. In order to establish the alternating magnetic field and induced magnetic flux and the demand of electric power is called reactive power. Reactive power does not do any work, but it will occupy the capacity of the transmission and transformation equipment and reduce the application rate of the equipment. In short, active power is the power consumed by the equipment and converted into other energy. Reactive power, is to maintain the operation of equipment, but does not consume energy. Reactive power exists between the power grid and equipment, and is an indispensable energy part of the power grid and equipment.

3. Power factor

Power factor: is the data used to weigh the efficiency of electrical equipment (e. g. transformers, transmission lines, etc.). Power factor = active power/apparent power.

cos φ = P/[(P2 Q2)^(1/2)], the closer Q is to 0, the greater the power factor.

The power factor is an indicator that reflects the proportional relationship between reactive energy and active energy in electrical energy. This index value is closer to 1, means that the reactive power in the power grid system activities closer to 0, can reduce the power loss caused by reactive power system, at the same time, the user side can also prevent the power supply bureau's reactive fine due to the low power factor.
