1.Why is reactive power compensation necessary? Reactive power is by no means useless power. In AC power supply systems, inductors and capacitors serve as essential loads. Ferromagnetic loads—such as electric motors and transformers—cannot function without inductive reactive power for excitation; meanwhile, long-distance transmission lines possess inherent capacitive characteristics, effectively a...

In modern power systems, reactive power compensation is widely used to improve power factor, reduce line losses, and increase the efficiency of electrical equipment. However, when the power source is a diesel generator, gas generator, or other synchronous generator, pursuing an extremely high power factor is not always a good idea. At first glance, a power factor close to 1.00 seems ideal. But for...

In power quality management, different voltage levels often require different harmonic mitigation strategies. In low-voltage systems, Active Harmonic Filters (AHFs) are widely used because they offer flexible and precise harmonic compensation. However, when it comes to medium- and high-voltage power systems, passive Filter Capacitor (FC) systems remain a more common and practical solution. So, why...
