SVG Power Factor Correction

Jinneng electric SVG power factor correction is an advanced power electronic device for dynamic reactive power compensation and power quality improvement. Representing the highest level of reactive power compensation technology, it serves as a modern replacement for traditional capacitor-reactor compensation systems.

 

 

The heart of an SVG is a voltage-source converter. Using fully-controlled power electronic switching devices (such as IGBTs) and PWM (Pulse Width Modulation) technology, it inverts the DC voltage from a capacitor into a three-phase AC voltage synchronized with the grid.

 

When the system requires capacitive reactive power: The SVG outputs an AC voltage slightly higher than the grid voltage, generating a leading current (equivalent to an "intelligent capacitor").

When the system requires inductive reactive power: The SVG outputs an AC voltage slightly lower than the grid voltage, generating a lagging current (equivalent to an "intelligent reactor").

By precisely controlling the amplitude and phase of its output voltage, the SVG can instantaneously, continuously, and smoothly generate or absorb reactive power.

Characteristic	Static Var Generator (SVG)	Traditional SVC (e.g., TSC/TCR)
Response Speed	Extremely Fast (≤ 1-10 ms)	Relatively Fast (20-40 ms)
Compensation Method	Continuous, Smooth, Stepless	Step-wise, Discrete
Harmonic Characteristics	Does not generate harmonics; can also filter harmonics	TCR itself generates significant harmonics, requiring additional filters
Low-Voltage Performance	Reactive current output capability unaffected by system voltage	Reactive power output decreases sharply with voltage drop
Three-Phase Imbalance	Can easily achieve phase-by-phase compensation	Limited compensation capability or high implementation cost
Size & Losses	Compact size, but higher initial investment and operating losses	Large footprint, lower initial investment

 

 

Static reactive power compensation devices (SVG) are widely used in many industries, mainly for improving the stability and power quality of power systems.

• In oil and coal mining, SVG can optimize the power factor of high-power equipment and reduce energy consumption.
• In new energy sectors such as wind and solar, SVG helps balance reactive power and ensure stable grid-connection.
• In data centers and industrial manufacturing, SVG can reduce voltage fluctuations and improve equipment efficiency.
• In commercial cemter and public facilities, SVG helps to reduce electricity bills and improve the reliability of the electricity supply.
