STATCOM – Static Synchronous Compensation

Modern power grids face increasing challenges in maintaining stable and reliable voltage regulation amidst growing power demand and the integration of renewable energy. Changes in load and generation can cause voltage fluctuations, harmonics, and reactive power issues that threaten grid stability and power quality.

STATCOMs enhance grid stability with dynamic power system compensation

As rapid-response shunt devices with advanced capabilities for voltage control, reactive power compensation, and active power flow management, STATCOMs will play an increasingly vital role in optimizing grid performance and stability.

Advantages of STATCOM

STATCOMs provide several major advantages to electrical grids, including:

Improved Grid Stability

STATCOMs help maintain system stability during transient events by providing fast-acting, reactive power compensation. This allows for better control over power system oscillations and improves transient stability.

Increased Power Flow Control

These systems can control both active and reactive power flow in transmission lines by adjusting the magnitude and phase angle of the output voltage. This enhances the transmission line ability to transfer power in weakly interconnected systems.

Reduced Transmission Losses

By optimizing reactive power flow, STATCOMs help reduce transmission losses and improve transmission efficiency.

Improved Voltage Profile and Power Quality

STATCOMs regulate voltage at the connection point, correcting for sags, swells, and transients. This results in improved voltage profile and power quality for sensitive industrial loads.
