STATCOM STATCOM (Static Synchronous Compensator)continuously provides variable reactive power in response to voltage variations, supporting the stability of the grid. STATCOM operates according to voltage source converter (VSC) principles, combining unique PWM (pulse width modulation) with millisecond switching. STATCOM functions with a very limited need for harmonic filters, contributing to a sma...

Power factor is the percentage of consumed power(KW) versus supplied power(KVA). This is important because a low power factor can waste energy, result in inefficient use of electrical power, and often result in higher energy bills. Power Factor Correction will improve the energy efficiency of any electrical system, but a reduction in your power bill is only available where a power company charges ...

Harmonics in power system. In an electric power system, a harmonic is a voltage or current at a multiple of the fundamental frequency of the system, produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated magnetic devices. Harmonic frequencies in the power grid are a frequent cause of power quality problems. Harmonics in power systems result in increased hea...
