(statcom/svg) Static compensator


We provide IGBT based power electronic active dynamic unit called STATCOM.

STATCOM is a Step less Variable Source of Reactive Power that can provide both Capacitive and Inductive power. It has distinct advantages and is ideal for demanding applications such as those prevailing during highly fluctuating load conditions and varying reactive power requirements of Grid connected power generating units. STATCOM for Grid Connected Solar Plants can provide Dynamic Reactive Power support for voltage Control.

The purpose of the Dynamic compensation system at solar power exporting facility is to minimize import of reactive power both inductive and capacitive from the Grid.

Statcom has multifold capabilities of

  • Reactive Power Compensation, Harmonic Filtration, flicker control, unbalance control etc.
  • Step-less compensation capable of injecting capacitive or inductive power on a real-time basis.
  • Voltage and Reactive Power control for stable power system operation
  • Reduced voltage fluctuations.

Clariant Static VAR Generator is a Step-less Solution to improve Power Factor. The use of most advanced controllability of 3-Phase 3-Level IGBT based voltage source inverter architecture, CPSL SVG does precise power factor and unbalance correction without the need of any passive power factor correction capacitors. These SVGs are designed in stackable modular configuration for increased resilience, reliability and redundancy.

CPSL SVGs are powered with a sophisticated Artificial Neural Network-based control algorithm to achieve a set power factor, while always working in the background for real-time loss minimization, to achieve improved energy efficiency.
