Merus STATCOM

Merus STATCOM

Merus Static Compensators (STATCOMs) are part of the Merus FACTS product family and built on modern IGBT power electronics technology. Merus STATCOMs are designed to provide real-time reactive power compensation and active harmonic filtering in demanding applications. Merus STATCOMs 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 STATCOMs enable grid code compliance. Transmission and distribution utilities benefit from Merus STATCOMs in the form of improved transmission and distribution capacity. Merus Power provides STATCOM solutions up to 38.5kV levels. Merus Power can supply a complete turnkey solution.

Applications

Heavy industrial loads, such as arc furnaces, welding equipment, rolling mills and heavy induction motors used in mining and harbor environments, etc., significantly impact the stability of electric grid operation by causing flicker, voltage unbalance and harmonic distortion. With its ultra-fast response time of less than one millisecond, Merus STATCOM provides excellent compensation of reactive power and harmonic distortion even for the most rapidly varying heavy loads. Thus plant productivity can be increased and harmful power quality challenges, including flicker and harmonic distortion, can be effectively eliminated.

Wind and solar farms have to conform to regulatory power quality requirements known as grid codes. Voltage variations and harmonic distortion caused by renewable generation in varying climatic conditions is easily compensated by connecting Merus STATCOM to the power plant.

Transmission and distribution grids face rapid changes in reactive power demand from constantly fluctuating loads. This leads to significant voltage variations and may even cause a complete voltage collapse under certain severe conditions. Merus STATCOM is an excellent and scalable solution for grid voltage stabilization by fast reactive power compensation in varying loading conditions.

Application areas include
  • Steel industry (electric arc furnaces (EAFs), rolling mills, etc.)
  • Mining (Mine winders, excavators, conveyors)
  • Shredders and crushers
  • Welding
  • Cement plants
  • Traction
  • Harbor cranes
  • Voltage and reactive power control in transmission and distribution utilities
