STATCOM (Static Synchronous Compensator) is a device used in power transmission systems to regulate voltage and provide reactive power support. It is a type of FACTS (Flexible AC Transmission System) device that actively controls the flow of electric power and improves the performance of the transmission system.

The main function of a STATCOM is to control the reactive power flow in the power grid. This is done by injecting or absorbing reactive power into the system to manage voltage levels and power factor. By controlling the reactive power flow, STATCOM helps maintain voltage stability and improves the overall power system performance.

STATCOM consists of power electronics-based converters, usually using Insulated Gate Bipolar Transistors (IGBTs) along with control systems. It is typically connected in parallel to the transmission system and can quickly respond to changes in the system conditions.

When the system voltage is low, STATCOM injects reactive power, thereby raising the voltage level. Similarly, when the system voltage is high, STATCOM absorbs reactive power, which helps reduce the voltage. This dynamic voltage regulation capability makes STATCOM valuable in mitigating voltage fluctuations, voltage sags, and voltage flicker in the transmission system.

One of the significant advantages of STATCOM is its ability to provide rapid response for reactive power control. Its fast-acting control system can quickly adjust the reactive power output to stabilize the voltage and maintain the desired voltage profile. This makes STATCOM a useful tool for voltage control, power factor correction, and maintaining system stability in power transmission.

In summary, STATCOM is a power electronic device used in power transmission systems to regulate voltage and provide reactive power support. Its dynamic control capabilities make it an essential component in maintaining the stability and reliability of the power grid.

Statcom, sometimes is called as Static Var Generator, we can provide 6kV~35kV Static Var Generator. It can be outdoor type or Indoor type, with air cooling or water cooling system.
