STATCOM

A static synchronous compensator (STATCOM), is a regulating device used on alternating current electricity transmission networks. It is based on a power electronics voltage-source converter and can act as either a source or sink of reactive AC power to an electricity network. If connected to a source of power it can also provide active AC power. It is a member of the FACTS family of devices. It is inherently modular and electable. Press the logic source to see an example of voltage drop regulation... When the STATCOM is connected it provides the additional reactive power required to raise the voltage back to 230V rms... Note that when the STATCOM is connected it produces a significant harmonic distortion, In reality the STATCOM operates in high switching frequencies (e.g. 10 KHz) with PWM modulation and in that case the harmonic distortion is very small...
