A modern power quality solution for heavy industry and utilities.


Static Synchronous Compensator (STATCOM) is part of the Merus product family and built on modern IGBT power electronics technology. Merus STATCOM is designed to provide real-time reactive power compensation and active harmonic filtering in demanding applications. Merus STATCOM minimize voltage variations and mitigate flicker caused by heavy industrial loads, such as electric arc furnaces (EAFs), mine winders, harbor cranes, excavators, etc.

In wind and solar farms, Merus STATCOM enable grid code compliance. Transmission and distribution utilities benefit from STATCOMs in the form of improved transmission and distribution capacity. Elco Power provides STATCOM solutions up to 38.5kV levels. 

ELCO Power can provide a complete turnkey STATCOM solution.

How STATCOM Works?

STATCOM can be understood as a controlled current source connected in parallel with the load to be compensated. It can produce both capacitive and inductive reactive power thanks to its ability to vary the phase angle and the magnitude of its output current dynamically. Merus STATCOM responds instantly to changes in the reactive power demand of the load it is set to compensate and thus ensures that reactive power supply from the power grid is kept at the minimum.

The main components of the STATCOM system are DC link capacitors, high frequency semiconductor switches and a filtering circuit. The DC link capacitors are the source of reactive power. The multilevel IGBT bridge uses the energy stored in the DC link to produce any kind of current waveform at the STATCOM output with fast IGBT switching. The brain of the system is the Modular Controller Concept (MCC) that measures the network current, separates the reactive and harmonic components and controls the IGBTs according to the assigned compensation settings. STATCOM can be connected either in open-loop or in closed-loop configuration. (More Info)
