In power distribution systems, capacitor banks compensate for the reactive power generated by inductive loads using parallel-connected low-voltage power capacitors; this improves the power factor, reduces line losses, and avoids utility company penalties. However, a common misconception exists: the belief that the more capacitors are engaged—and the higher the resulting power factor—the better. In...

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...

Can PCS Replace a Dedicated SVG? With the rapid development of battery energy storage systems (BESS), many people ask whether the reactive power compensation function of a PCS can replace a dedicated SVG. The answer is: Sometimes yes, but not always. 1. PCS: Energy Conversion with Reactive Power Support PCS (Power Conversion System) is mainly used to convert electrical energy between the battery a...
