The determination of the appropriate compensation capacity is an absolutely crucial aspect in projects where the installation of reactive power compensation devices, such as capacitor banks, Static Var Generator (SVG), or Hybrid reactive power compensation devices, is imperative. For new projects: In new projects that are currently in the design stage, the required compensation capacity (kVAr) can...
The History Of Reactive Power Compensation If you are in the power industry, you must have heard of reactive power compensation. But you may not know much about it. What is reactive power compensation? Electricity from the power grid comes in two types: First, there's active power. This is the electricity that does the direct work, turning into motion, heat, chemicals, or sound to...
Introduction to Low Voltage Reactive Power Cabinet Power distribution equipment forms the backbone of modern electrical systems, efficiently managing and allocating electricity to ensure seamless power supply across various sectors. There are control gadgets that help manage how electricity flows, safety features like circuit breakers to prevent accidents, and measuring tools to check how much pow...
Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of blocking AC and blocking DC, that is, in the AC circuit, the characteristics of inductive reactance are used to pass low-frequency DC and block high-frequency AC. The capacit...
What is the power factor correction? Power factor correction (PFC) is a technique used to improve the power factor of an electrical system. Power factor is a measure of how effectively electrical power is being used. It is defined as the ratio of real power (measured in kilowatts, kW) used to perform work to the apparent power (measured in kilovolt-amperes, kVA) drawn from the power source. Power ...
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...
Development history of IGBTThe Insulated Gate Bipolar Transistor (IGBT) has revolutionized power electronics since its inception, marking a pivotal milestone in the development of high-efficiency energy conversion systems. Born in the late 1970s and early 1980s, the IGBT emerged as a hybrid semiconductor device that combined the advantages of Bipolar Junction Transistors (BJTs) and Metal-Oxide-Sem...
