The correct compensation capacity is very important for projects, where need to install reactive power compensation device, such as capacitor banks, or Static Var Generator SVG, or Hybrid reactive power compensation device. For new projects: New Projects which are at the design stage: The required compensation capacity (kVAr) can be calculated using Power Factor Calculatation tools. Our YT'...
Power Qualty Cause The transmission of electricity from the power grid to the load side is mainly carried out using a three-phase line. Most of the industrial loads are also three-phase loads. The three-phase voltages produced in synchronous generators can be considered sinusoidal and symmetrical. The reason for the voltage and current distortion at a given point in the supply network is the wides...
Introduction In our modern world, the reliability and efficiency of electrical systems are more critical than ever. However, a common challenge that often goes unnoticed is harmonic distortion. This distortion can cause various problems, from decreased efficiency to equipment damage. To combat this, harmonic filters come into play. There are two main types: active harmonic filters (AHFs) and passi...
Hybrid power factor correction refers to a combination of capacitor banks and power electronic converters (such as Active Power Harmonic Filter or Static Var Generator) used to improve power factor and mitigate harmonics in electrical power systems. The advantages of hybrid power factor correction over capacitor banks alone include: Power Factor Correction: Hybrid solutions offer dynamic and preci...
Static VAR Generator (SVG) and Active Power(Harmonic) Filter (APF or AHF) are both devices used in power systems for Power Factor Correction and Power Quality Improvement. However, they serve different purposes and have different functionalities. Static VAR Generator (SVG):Static VAR Generator is a power electronics-based device used to provide dynamic reactive power compensation in electrica...
Modular IGBT and single tube IGBT are two different packaging forms, and they have significant differences in multiple aspects: Packaging form: The packaging of single tube IGBT is relatively small, usually using packaging such as TO-247 or TO-220. This packaging makes it more suitable for low-power applications. Modular IGBT is an electronic module that integrates multiple IGBT transistors, free ...
Ultra-high harmonic detection in distribution networks relies on advanced technologies designed to measure and analyze harmonics beyond the conventional limits. Here are some key technologies used for ultra-high harmonic detection: Wideband Spectrum Analysis: This technology involves using wideband spectrum analyzers capable of analyzing frequencies well beyond the conventional range to detect and...
IGBT switching frequency The switching frequency of IGBT refers to the frequency at which it is turned on and off, usually expressed in Hertz (Hz). The frequency of switching directly affects the switching loss, efficiency, volume, weight, and heat dissipation design of power electronic systems. Switching loss refers to the energy loss generated by IGBT during the opening and closing proces...
