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...

STATCOM A static synchronous compensator, known as a STATCOM, is another device used to regulate the power factor in medium to high voltage applications. They operate on roughly the same principles as a synchronous compensator, however, use a voltage source converter as opposed to a rotating machine to provide dynamic Power Factor Correction. STATCOMs use IGBT switching te...

Power quality problems and Industry background Dynamic reactive power, lower power factors, and higher harmonic content are common power quality problems in the CNC industry. Major contamination sources of power quality include the punching machines,welding machines. When harmonics occur, dynamic reactive current and 3-phase imbalance are produced. During the CNC period, the power factor of arc fu...

Voltage Sag Voltage sag is the main problem to cause the losses of industrial production. Unpredictable outage rarely happen in many high automated process control industries. who have the good power supplies. Voltage Sag is mostly caused by thunder,but it also has other reasons. Power system cause: starting of heavy machine and short circuit fault. Unpredictable accident:traffic accident,construc...

Power factor correction Connected equipment (transformers, motors, air-conditioning, refrigerators, etc.) cause a phase angle between current and voltage.When the current is phase-shifted, it takes more current to deliver the same amount of active power. Impact of reactive power • Transmission equipment has to be sized for the apparent power, yet only active power is useful • Increased losses in t...
