Static VAR Compensator At the medium voltage level, one common of reactive power compensation is Static Var Compensators (SVCs). SVCs are typically installed in electrical power systems to regulate the voltage and compensate for reactive power fluctuations. They consist of various components such as thyristor-controlled reactors (TCRs) and thyristor-switched capacitors (TSCs) that can quickly adju...

A Static Synchronous Compensator (STATCOM) is a power electronic device used for voltage control and reactive power compensation in electrical power systems. It is typically connected to the grid and is capable of injecting or absorbing reactive power to regulate the system voltage. The control of voltage by a STATCOM is primarily achieved by manipulating its reactive power output. Here's a basic ...

Why adjust the power factor of a generator? 1. When the generator is running, the power factor is too high, that is, the reactive power is too low, which reduces the reactive power margin of the system and affects the steady-state stability of the generator. Although the economy is improved, in the long run, this is in exchange for an increased probability of accidents. Once an accident occurs, th...

What is harmonics issues in AC and DC grid? In AC and DC grids, harmonics refer to the presence of frequency components that are integer multiples of the fundamental frequency. Harmonics can be problematic because they can cause various issues such as: Voltage and Current Distortion: Harmonics in the grid can distort the shape of the voltage and current waveforms, resulting in distorted sine waves...
