High voltage static var generator reactive power compensation device
Description
ZBSVG is currently the most advanced reactive power compensation technology,and its compensation device based on a voltage source converter has achieved a qualitative leap in reactive power compensation methods. It no longer uses large-capacity capacitors and inductors, but realizes the conversion of reactive energy through high-frequency switches of high-power power electronic devices.
Technically speaking, ZBSVG has greater advantages than traditional reactive power compensation devices. Harmonic sources are generally non-linear loads, such as rectifiers, frequency converters with rectification links, and a large number of equipment with switching devices, etc., which generate harmonic currents; power supply systems are generally protected objects, that is, to achieve the ultimate inflow or outflow The current of the system is a sine wave with very little harmonic content. Compared with passive filter devices, active filter is a dynamically changing compensation device with better dynamic performance.
Applications
Steel, metallurgy, petrochemical, railway, wind power, large hoist, substation and other industries.
Advantages
1.Faster response time:ZBSVG response time:<5ms.
2.Ability to suppress voltage flicker is stronger, suppression of voltage flicker can reach 5:1, and response speed is fast.
3.Compensation function is diversified, and different compensation functions can be realized.
4.Using PWM technology, not only the harmonic content generated by itself is extremely low, but also the harmonic and reactive power of the load can be compensated to realize the function of active filtering.
