What Is The Function Of Ac Reactor?

AC Reactors plays multiple important roles in the power system. Here is a detailed explanation of its main functions:

Suppressing harmonics and surges: AC reactors can effectively suppress harmonic components in current, reduce the interference of harmonics on the power system, and protect the safe operation of electromechanical systems. At the same time, it can also reduce surge and peak currents and protect power electronic components from transient overvoltage damage.
‌Improving voltage distribution and improving stability: Reactors can improve voltage distribution, especially when the power equipment is heavily loaded or the system is short-circuited, which can reduce the voltage burden of equipment such as transformers and prevent equipment from overload operation.
It can also improve the stability of the power system and reduce voltage fluctuations caused by load changes or power system failures, thereby avoiding power system collapse and power outages.
‌Reducing power frequency transient overvoltage: When a short circuit fault occurs in the system or a transition process occurs, a transient overvoltage will be generated. Reactors can reduce this power frequency transient overvoltage and protect power equipment from overvoltage damage.
‌Improve power factor and compensate reactive power‌:

Reactors can be used to compensate reactive power, improve the power factor of the system, and thus improve the efficiency of the power system‌.

By properly configuring reactors, line losses can be reduced and the quality of power supply can be improved‌.

Protect power equipment‌:

Reactors can protect power equipment from interference and damage such as high temperature, overvoltage and harmonics, and extend the service life of the equipment‌.

In power electronic equipment such as frequency converters, reactors are often used in filter circuits to smooth output voltage and current, reduce ripple, and further protect equipment‌.

Enhance anti-interference‌:

Reactors can also improve low-frequency conduction anti-interference and prevent tripping caused by voltage spikes of the main power supply, thereby ensuring the stable operation of the power system‌.

In summary, AC reactors play a vital role in power systems. They provide strong guarantees for the safe, stable and efficient operation of power systems by suppressing harmonics, improving voltage distribution, reducing overvoltage, improving power factor, protecting power equipment and enhancing anti-interference.
