    Compared with traditional SVC devices represented by TCR, Static Var Generator (SVG) has a faster adjusting speed, wide operating voltage, and greatly reduces the carrier frequency harmonics and compensaties current after adopting multiple, multi-level PWM technology. What is more, the components which are used  in SVG are far smaller than SVC’s, so the size of the device can be reduced.  NPV and  NSVseries of SVG represent the development direction of  dynamic reactive power compensation with such advantages.


    NPV series of SVG have realized universal coverage of the power systems, and  can be widely used in different industries and conditions. According to the voltage grade used  by users, the SVG has been divided into 200 V, 400 V, 600 V and  even  higher  voltage series.  Modularization of power units makes it more compant and it  is easy to expand. Reliability of the whole machine is greatly improved  because of  the independence of each  module.


    ØFeatures

    ØApplication Areas

    1.200V,400V,600V,750V,1140V,Rated capacity up to 10Mvar;
    2.The fault module does not affect the operation of  other modules and can be replaced by elements with high reliability;
    3. Modular Parallel Design. Each module unit can be used for active power compensation independently or at the same time;
    4. Strong ability to control the voltage fluctuation and flicker. Damped harmonic oscillator of power system;
    5. Using PWM technology which own harmonics are low;
    6. Increased capacity,reduced pawer loss,purify power;
    7. Fast response(less than 3ms),low power consumption,small footprints.

    1. The power system which needs comprehensive compensation of reactive power and harmonics.
    2. Electric Pawer industry which use a special AC voltage.
    3. The power system in low power factor areas, such as factories, enterprises, etc.
    4. Production enterprise using a high-power and nonlinear load.(for example, air pump etc.)
    5.Remote areas with a poor condition of electricity, such as rural, mountainous area and wind farm.
    6. The power system which has a demand for high quality power grid, such as hospital equipment etc.
