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...

In low-voltage power factor correction systems, detuned reactors are widely used together with capacitor banks to prevent harmonic amplification and protect capacitors. Among the most common configurations, 7% and 14% detuned reactors serve different purposes and require different capacitor specifications. A 7% detuned reactor typically creates a tuning frequency of approximately 189 Hz in a 50 Hz...

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...
