SVG Static VAR Generator Compensating System

SVG Static VAR Generator Compensating System also called as SVG Reactive Power Compensation Cabinet,integrates the core power units, control system, reactors, circuit breakers, and other components of an SVG into a cabinet, forming a complete set of equipment for dynamic reactive power compensation and voltage support.

 

Its core function is to rapidly and continuously generate or absorb reactive power to stabilize grid voltage and improve the power factor.

The SVG Static VAR Generator compensating system is widely used in petroleum, coal mining, traffic system, new energy, computer lab, communication, metallurgy, chemical industry, automotive industry, communal facility, commercial plaza, bank, hospital, theater, radio and television, amusement park, power grid hub substation, wind power plant, power system and more than thirty other industries.

 

 

 

Jinneng electric Static Var Generator compensating system is a power electronics-based device that is in parallel with loads that require harmonic mitigation. SVG can provide any type of current waveform in real time as a controlled current source.

When the load generates inductive current or capacitive current, the load current will lag or advance ahead of the voltage. SVG detects the phase Angle difference and injects the leading or lagging current into the power system in real time, so that the current phase Angle is basically the same as the voltage phase Angle, and the fundamental power factor tends to be the same.
