The static reactive generator is the latest technology representative in today's reactive power compensation field. It can quickly and dynamically compensate for reactive power and harmonics, suppress voltage fluctuations and flicker, thereby improving the power factor and transmission system stability. SVG has the advantages of fast response, wide compensation range, diversified compensation functions and small area, which has become the development trend of power quality control.

Second, the use of the environment:

Installation: indoor installation, optional fixed way, the cable into the line optional

Ambient temperature: -25 ℃ ~ +55 ℃

Storage temperature: -40 ℃ ~ 65 ℃

Relative humidity: up to 95%, no condensation

Altitude: Installation of less than 2000 meters above sea level (other special needs to be customized).

Third, product characteristics:

SVG is self-commutating IGBT bridge converter for dynamic reactive power compensation device, is the best solution in the field of reactive power control. Compared with the traditional modulation camera, capacitor reactor, thyristor control reactor TCR as the main representative of the traditional SVC and other ways.

Fourth, technical advantages:

· Bidirectional compensation: SVG can be used as a capacitor bank to send reactive power, can also be used as a reactor to absorb reactive power.

· Continuous capacity compensation: You can continuously issue inductive reactive power and capacitive reactive power, high compensation accuracy.

· Operating loss: efficiency> 99.2%; usually, the same capacity loss: SVG <1/2 × TCR, SVG <1/3 × MCR.

· Small footprint: no filtering branch, less than 1/5 ~ 1/3 of SVC, especially suitable for the occasions with higher occupied area.

· Fast response: Based on IGBT device and control technology, response time less than 5ms, better voltage fluctuation and flicker suppression 6.

· Low voltage characteristics: SVG output current remains unchanged 1.0 (even running in the short-term overload zone, increase the output current); system voltage dropped from 1.0 to 0.5, SVG SVW output reactive power is 2.5 times.

· Harmonic characteristics are good: the use of advanced multi-level chain circuit topology to step-wave approximation of the sine wave, resulting in a very small harmonic.

Fifth, Usage:

· Maintain voltage stability: Dynamically maintain the system voltage stability, reduce the impact of voltage fluctuations, prevent transient voltage collapse.

· Reduce the number of switching switch: with the capacitor, reactors, regulating transformers in use, reduce the switching frequency of the capacitor bank and the reactor bank switch, reducing the decomposition of switching transformer load regulation, increase equipment life.

· Improve the power factor of industrial users: the power company to assess the results of industrial power factor of industrial users rewards and punishments, Improve power factor will bring direct economic benefits, reduce the line loss.

· Eliminate the system of harmonic pollution: effectively filter the frequency control, rectification load generated 13 times and the following harmonics on the system and electrical equipment.

· Realize negative sequence compensation: Angular SVG can realize the negative sequence compensation and reduce the system voltage unbalance caused by the load.

· Solve the capacitor group often over-current or skewer resistance problems: In systems with large harmonic currents, capacitor banks often experience overcurrent loss or skew resistance, and similar capacitor problems can be avoided with SVG compensation.
