STATIC SYNCHRONOUS COMPENSATOR
Statcom (Static Synchronous Compensator) is a converter based
digital controlled FACTS device providing complete solution for
reactive power, harmonics, voltage unbalance, voltage fluctuations
and neutral current problems. Statcom provides simultaneous
solution to power quality problems according to operating priorities
selected by user.

OPERATION PRINCIPLES
• Statcom is a controlled current source device
with IGBT based converter technology.
• Reactive power is transferred through a coupling
reactor in capacitive and inductive regions by
the generation of magnitude controlled voltage

• Statcom is able to inject anti-phase low order har-
I monic currents to minimize current distortion at supply
side. Harmonic filtering is limited to most common LV
network harmonics which are 3 rd, 5 th, 7 th,11 th and 13 rd
harmonics.
• Unsymmetrical load currents are balanced by inject-
ing negative sequence currents to the network.
• STATCOM provides the best voltage regulation perfor-
mance during voltage sags/swells by using its overload
capability in addition to fastest reactive power
generation.
