What is the reason of resonance in power networks? Resonance in power networks occurs when the inductive and capacitive elements of the system interact in a way that amplifies specific frequencies, leading to excessive voltage or current oscillations. Here are the primary reasons for resonance in power networks: 1. Impedance Matching Resonant Frequency: Every electrical circuit has a natural reson...

Inverters are a type of power electronic device widely used in industrial automation. They adjust the speed of motors by changing the frequency and amplitude of the motor input voltage. Although inverters improve energy efficiency and control performance, they generate harmonics during operation, which have an adverse effect on power grids and equipment. Understanding the causes and principles of ...

In the power supply system, reactive power compensation can improve the power factor of the power grid, reduce the loss of power transformers and transmission lines, and improve the power supply environment. Reasonable selection of compensation devices can minimize the loss of the power grid and improve the quality of the power grid. If the selection or use is improper, it may cause many problems ...
