Product Description
Compared with the traditional SVC device represented by TCR, the static var generator (SVG) has a faster adjustment speed and a wider operating range, and after adopting multiple and multi-level PWM technology measures, the compensation current is greatly reduced. The content of the carrier frequency Nuobo, and more importantly, the reactors and capacitors used in SVG are much smaller than those used in SVC, which will greatly reduce the size of the device. The VPV series low-voltage static var generator (SVG) has such advantages and represents the development direction of dynamic reactive power compensation devices.
The VPV series SVG developed and produced by our company realizes full coverage of the power system and is widely used in different industries and working conditions. According to the user's voltage level, it is divided into 200V series, 400V series, 600V series and high voltage series. The modularization of the power unit makes the capacity of the device easy to expand, and the independence of the module greatly improves the reliability of the whole machine.
Features
Adopting modular design, each module unit can compensate reactive power and various waves individually or simultaneously
Strong ability to control fluctuation and flicker
Using PWM interleaving technology, its own harmonics are extremely low
Fast response speed, less than or equal to 3ms
Low power consumption and small footprint
Increase grid capacity, reduce losses, and purify grid
Design life of 20 years
Convenient installation and debugging, no wearing parts, maintenance-free
Application field
Electricity systems that require comprehensive compensation for reactive power and congestion
Manufacturers that use high-power nonlinear loads and shock loads (such as air pumps, etc.)
Electrolysis industry using special AC voltage
Remote areas with poor electricity consumption, such as rural areas, mountainous areas, wind farms, etc.
Power system in areas with low power factor, such as factories, enterprises, etc.
Power systems that require high power grid quality, such as hospitals
high pressure
The VPV series of high-voltage static var generators are mainly used in high-voltage systems such as 6kV, 10kV, 27.5kV and 35kV. The modular design improves the reliability of the whole machine. The adjustment speed of the high-voltage static var generator (SVG) is faster and the operation Wide range. Moreover, after adopting multiple, multi-level and other PWM technical measures, the content of carrier frequency harmonics in the compensation current is greatly reduced. More importantly, the reactor and capacitive components used in the high-voltage static var generator (SVG) should be small, which will greatly reduce the size of the device.
