Dynamic Voltage Restorer has the capability of 0-100% transient voltage compensation, harmonic current control, reactive power compensation and energy management, in which transient voltage compensation can be switched from other compensation modes to transient voltage compensation mode quickly, the voltage swell and sag in distribution network can be responded quickly. At the same time, it adopts self-learning intelligent control technology, combines the energy storage control and power quality management, and provides an effective integrated solution for voltage sag sensitive industry.
Application fields:
It can be widely used in semiconductor manufacturing, petrochemical, chemical, automobile manufacturing, precision processing, pharmaceutical, paper, medical and health, scientific research institutes, tobacco, metallurgy, steel, printing, glass, textile and other industries with high demand for power supply and strict requirements for power quality.
0-100% rated voltage perfect compensation, compensation time can be customized design.
Can simultaneously control control voltage sag, voltage swell, short-term interruption and other issues.
The system adopts multiple redundancy design and has high stability.
With voltage adjustment target value that can be set on site. The factory default value is - 15% ~ + 15%.
Fast switching, and transient full response time not more than 5ms.
The over-voltage regulation range is wide and the regulation ability is strong.
Maintenance free, and manual duty free.
Power level: 600-1500kva
Working mode: online dual conversion, output isolation
Special requirements can be customized
