STATCOM

Static Synchronous
Compensators

STATCOM Systems are powerful and cost effective ways to provide continuous voltage regulation, improve voltage stability, fulfill the grid compliance requirements and provide dynamic grid support where it’s needed.

Primary Benefits

  • Power factor correction
  • Voltage regulation improvement
  • Flicker mitigation
  • Load balancing
  • Voltage ride through support

Application Areas

  • Transmission and Distribution Systems
  • Metal Industry
  • Mining Industry
  • Railway Transmission Systems
  • Grid code compliance applications of solar and wind energy systems

STATCOM Features

  • Voltage source converter (VSC) based shunt compensation system
  • Can provide both inductive and capacitive reactive power
  • Flicker mitigation
  • Features
  • Power factor correction
  • Voltage regulation
  • Flicker compensation
  • Voltage ride through support
  • Load balancing

Fundamentals

The generated reactive power is changed with the amplitude
of the output voltage of VSC

Better dynamic response, < 20ms

Reduced installation footprint

Grid voltage independent performance

High short time overload capacity

Much lower operation losses

Low initial cost

Less maintenance and operational costs

Better for high power, high voltage
