Static VAR Compensator (SVC)

Static VAR Compensator (SVC)

A weak power grid usually suffers from the voltage drop due to heavy loads. Many industry loads, like mining machine and electric furnace, always generate large amount of harmonic currents, heavy voltage flickers and drops. These problems can easily interrupt power supplies, lower product quality and even reduce productivity. To help utility and industry customers improve ...

Static Synchronous Compensator(STATCOM)

Static Synchronous Compensator(STATCOM)

High-power rapid impact loads and rapid growth of asymmetrical impact loads can lead to considerable reactive disturbances in power systems. Ultimately, affecting power stability, power quality and the economic operation of power grids. Additionally, the overcurrent and overvoltage caused by these disturbances may damage the associated electrical apparatuses. Maintaining ...

Series Compensation

Series Compensation

The main purpose of using series compensation in a power system is virtual reduction of line reactance in order to enhance power system stability and boost the transmission capacity of existing and new transmission lines. Due to the deregulation of power market the existing transmission assets are to be utilized to the maximum extent to ensure efficient investment return. ...

Unified Power Flow Controller (UPFC)

Unified Power Flow Controller (UPFC)

Unified Power Flow Controller (UPFC) is the most advanced FACTS solution which provides independent active power and reactive power control of the transmission system. The UPFC is a combination of static synchronous compensator (STATCOM) and a static synchronous series compensator (SSSC) coupled via a common DC voltage link. Due to the dynamic and flexible control in both ...
