Reactive compensator is a kind of power electronic equipment used in power system, the main function is to compensate the reactive power to improve the power factor and stability of the power system. In the power system, if there is a large amount of inductive load, it will lead to a decrease in power factor, which will reduce the efficiency and stability of the power system. Reactive compensator can improve the power factor of power system and reduce the loss and cost of power system by compensating reactive power generated by inductive load.
Specifically, the reactive compensator uses the capacitive power load device and the inductive power load device in parallel in the same circuit to absorb and release energy, so as to achieve the purpose of reactive power compensation for the inductive power load device by releasing reactive power from the capacitive power load device.
In practical applications, reactive power compensators are widely used in many fields, such as industrial production, municipal buildings, power plants, public transportation and commercial fields. In these cases, motor, transformer and other load equipment or electric equipment operation will produce a large amount of reactive power, reactive compensator can effectively reduce power loss, improve the power supply quality of the grid, to ensure the normal operation of the power system.
In general, reactive power compensator plays a very important role in the power system, can effectively improve the efficiency and stability of the power grid, reduce energy waste, is one of the important equipment to ensure the normal operation of the power system.
