Static Var Generator - Less Than 5ms Response Time, Dynamic Reactive Power Compensation Functions, Low Harmonic Output Control

Basic principle
The static var generator (SVG:Static var generator for the) is self change phase bridge circuit through the reactor directly connected in parallel to the grid, the appropriate to adjust the phase and the amplitude of bridge circuit of AC side output voltage or direct control of the AC side current, you can enable circuit with a satisfied the requirements of reactive current, the realization of dynamic reactive power compensation.
A
Technical features
a Faster response
SVG response time: less than 5ms.
Svg can be within a very short period of time to complete from rated capacitive reactive power to the rated emotional power conversion, unparalleled in the response speed can be competent on the impact load compensation.
a Higher security
SVG is controlled as the current source, there is no possibility of resonance with the system impedance, the security is higher.
a Diversification of compensation functions
Using the same set of SVG device, it can realize different kinds of compensation functions:
Reactive power compensation;
Compensated load harmonic;
Compensated load imbalance;
At the same time, the compensation of the load, the harmonics and the imbalance.
a Low harmonic content
SVG uses PWM technology and multiplex technology, compared with the SVC TCR, the harmonic content is very low, the power grid will not produce two pollution.
a Smaller area
SVG adopts the direct PWM current control technology, its output current waveform and the phase.
