Overview
The GSC series SVG (Static Var Generator) by SIFANG. is a cutting-edge dynamic reactive power compensation device. The core of the system utilizes a mature cascaded structure from the power electronics converter domain. Each phase consists of multiple compact and standardized power units connected in series. Built on the company’s unified software and hardware control platform—proven in over ten thousand successful applications—the GSC series SVG delivers exceptional functionality, outstanding performance, and advanced control strategies. The GSC series SVG effectively mitigates voltage fluctuations, power factor instability, and harmonic distortions caused by the intermittent nature of wind and solar power generation, ensuring grid compliance and system reliability.

Suppress Voltage Deviation and Fluctuation
Maintain the stability of line and load-side voltages, suppressing voltage fluctuations and flicker.
Reduce Line Losses
Compensate for reactive power, improves power factor, and reduces line losses, enhancing overall system efficiency.
Suppress Voltage Unbalance
Eliminate negative sequence currents and suppresses three-phase imbalance, ensuring balanced and stable system operation.
Harmonic Compensation
Dynamic harmonic compensation, improving power quality and ensuring cleaner, more stable electrical supply.
Typical Cases
State Grid Xinjiang Kashgar Power Supply Company Taxian 220kV Substation Construction
This project installs a ±15Mvar direct-connected dynamic reactive power compensation STATCOM system under the 35kV bus. Each unit enables continuous and rapid reactive power adjustment within a -15Mvar (inductive) to +15Mvar (capacitive) range. The SVG is connected to the 35kV system via reactors and meets technical requirements for reactive power control, voltage regulation, and power factor improvement.
