In an electrical power system, harmonics basically means the multiples of the current or voltage at the fundamental voltage frequency. Whenever you look at a waveform and it's not the usual sinewave shape you expect, that means there are harmonics involved. What causes Harmonics? Well, AC signals can be divided into linear and nonlinear. The nonlinear systems draw power in short, sudden pul...
What is harmonic and how to manage it? Harmonics denote electrical quantities that possess frequencies which are integer multiples of the fundamental wave present in the current. This concept typically involves the Fourier series decomposition of periodic, non-sinusoidal electrical quantities. In this context, any electrical quantity with a frequency exceeding that of the fundamental wave, derived...
What are the power quality problems of broadband oscillation? Broadband oscillations in power systems refer to low-frequency oscillations that occur over a wide range of frequencies. These oscillations can have a significant impact on system stability and can lead to voltage instability, power quality issues, and even blackouts if not properly managed. Here are some of the characteristics of broad...
In today's rapidly advancing world, the reliability and quality of power have become more critical than ever. The interconnected systems and sensitive electronic devices of the modern digital economy require an almost perfect power supply. However, power quality (PQ) issues such as voltage sags, harmonics, and transients remain prevalent, posing significant challenges to utilities and end-users al...

What is the active power compensator? Active Power Compensator (APC) is an advanced power electronic device used to manage and optimize the flow of active power in electrical power systems. It helps to enhance power quality, improve voltage stability, and increase the overall efficiency of the power distribution network. APCs are particularly useful in applications where there are significant fluc...
How SVG compensation for leading reactive power? What kind of load is prone to generating leading power reactive power? Leading power factor conditions typically occur when a system has capacitive loads or a surplus of capacitive reactance over inductive reactance. Capacitive loads store energy in an electric field, unlike inductive loads that store energy in a magnetic field. When these lo...
Why Reactive power compensation is necessary on solar site? Backgaround With the development of the economy and the improvement of green energy awareness, more and more regions are using clean energy and installing a large number of solar power generation equipment. With the widespread use of photovoltaic power generation, many users have found that there are power adjustment fees, namely power fi...
