Why Does The Power Grid Need A Power Factor Correction Device?

Numerous motors, rectifiers, and other nonlinear loads can lead to a low power factor. These loads consume a significant proportion of reactive power, causing apparent power to far exceed actual active power demand, resulting in increased current. To deliver the same amount of active power, the power grid must provide more current, placing a significant burden on the distribution network and leading to higher losses and heat effects.

To alleviate this pressure, the industry has widely deployed capacitor bank for power factor improvement devices. The power correction device device can reduce the demand for ineffective current by injecting or absorbing reactive power to make the current waveform more consistent with the voltage waveform. For distribution transformers and lines, this reduces current peaks, lowers copper and iron losses, and improves overall power quality.

Furthermore, when reactive current is excessively high, harmonic components in the system are also amplified, threatening the voltage stability of the power grid and related equipment. power factor correction device industrial can, to some extent, regulate these harmonic effects, helping to maintain the purity of the voltage waveform and mitigate grid oscillations.
