In industrial production, enterprises often face two major challenges: fluctuating production efficiency and persistently high electricity costs. Most of the time, managers attribute these problems to aging equipment and improper operation by personnel, overlooking a hidden killer lurking in the power system—harmonics. As "electrical pollution" in the power system, harmonics not only directly incr...

Power Quality Insights In modern power systems, sensitive equipment and continuous operations are more vulnerable than ever to power disturbances. Among these disturbances, voltage sag is one of the most common and impactful. Although often brief, voltage sags can cause costly downtime, data loss, and even damage to critical equipment. In this blog, we'll explore what voltage sags are, their cause...

The quality of electricity directly determines the energy-saving ratio of a company's power consumption system, as high-quality electricity can prevent significant energy waste. So, what is electricity quality, and what factors affect it? What is power quality? Power quality generally refers to the quality of alternating current (AC). That is, the AC power supplied by the power industry to busines...

In power systems, the balance of reactive power is crucial, as it directly impacts grid stability and power quality. As an advanced dynamic reactive power compensation device, the SVG (Static Var Generator) is increasingly becoming an indispensable "stabilizer" within power systems. Today, let us take a closer look at the principles, advantages, and application scenarios of SVG dynamic reactive po...

Introduction In modern industrial, commercial and residential power grids, clean and stable sinusoidal voltage is the foundation for reliable operation of all electrical equipment. However, grid faults, nonlinear loads, switching operations and renewable energy integration constantly introduce various power quality issues. The waveform diagram clearly illustrates four most prevalent power quality ...

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...

APF and SVG are two important devices used in power systems to improve power quality. We frequently encounter them in our work; what are the differences between them, and what are their functions? 1.What is APF? The Active Power Filter (APF) is a specialized device for mitigating power harmonics, developed using modern power electronics and digital signal processing technology based on high-speed ...

The complete process of electricity generation and use can be clearly divided into four main stages: power generation → transmission → distribution → consumption. First, power plants convert various primary energy sources (such as coal, hydropower, wind power, nuclear power, and solar energy) into electrical energy. Then, the large amount of electricity generated by the power plants is efficiently...
