1.What is Harmonics? In power systems, the fundamental cause of harmonics is the presence of non-linear loads. When current flows through a load and does not maintain a linear relationship with the applied voltage, a non-sinusoidal current is formed, meaning harmonics are generated in the circuit. Harmonic frequencies are integer multiples of the fundamental frequency. As proven by the French math...

1. Introduction Three-phase unbalance is a prevalent power quality issue in low-voltage distribution systems, mainly caused by dispersed single-phase loads, charging piles and residential electricity consumption. Two mainstream solutions are widely used in the industry: mechanical relay phase-switching balancers and IGBT-based active compensation devices (SVG/APF/Active Load Balancer). This articl...

Analysis of the reasons for the decrease in power factor on the power supply side after the AHF only performs harmonic filtering: I. Increased total apparent power naturally leads to a decrease in the overall power factor. Power factor λ = P/S. Active power P is determined only by the fundamental active power; harmonics do not contribute. After filtering, the fundamental reactive power remains unc...

Many charging station operators have a question: when charging piles are charging normally, the power factor is perfectly within the standard range, and there are no problems even without capacitor banks or SVG. However, when the station is newly built, there is little traffic, or there is no one charging at night, the power factor inexplicably exceeds the standard, resulting in power factor adjus...

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...
