ZD-HVSVG series HV static var generator/SVG/STATCOM using IGBT as the core power modules which can quickly and continuously provide capacitive or inductive reactive power, achieve constant reactive power, constant voltage and constant power factor control through the assessment point, and ensure the power grid is running stable, high efficiency and high quality. In the power distribution network, the small capacity HV SVG/ STATCOM can significantly improve the power quality (improve the power factor, overcome phase imbalance, eliminate voltage flicker and fluctuation, restraining harmonic), if it is installed in some special loads (such as electric arc furnace).
HV SVG/STATCOM products use advanced instantaneous reactive power theory and power decoupling algorithm as the theory foundation, and adopt many technology such as modern power electronics, automation, micro-electronics and network communication. It can set reactive power nature and size, power factor and grid voltage as the control target, track power quality dynamically, adjust reactive power output, achieve setting curve and improve power quality.

■Better control for power grids, better load compensation, better power factor improvement
SVG/STATCOM increase system stability and power quality by providing voltage control and support, reactive power control, power oscillation damping, and increased power transfer capacity. STATCOM enables electro-intensive industrial processes to obtain a grid connection by controlling flicker level, harmonic voltage distortion, and voltage unbalance. STATCOM also allows renewables to be connected to the grid in compliance with grid code requirements by providing fault ride through support and voltage control.
■Optimal stability and quality
SVG/STATCOM is geared to quickly inject significant inductive or capacitive power. Thus the STATCOM provides improved dynamic stability of transmission systems to reduce the risk of voltage collapse and blackout while avoiding deterioration of the power quality due to its multilevel configuration: generating unwanted harmonics is widely avoided.
■In harmony with harmonics – and best flicker reduction
Harmonics generation is low due to the use of MMC technology, resulting also in low noise emissions.
The extremely fast control of SVG/STATCOM allows in industrial applications highly efficient flicker reduction and even active reduction of the lower harmonics caused by a nonlinear load such as an electric arc furnace.
■Fastest response – efficient solution
The standardized component design allows minimized engineering efforts and provides an overall fast, efficient, modular, and cost-effective solution.
ZDDQ SVG/STATCOM control with its most advanced concept offers unsurpassed speed in controlling the IGBT semiconductors to precisely generate the desired flow of energy between the converter and the feeding network.

Typical Application Fileds of HV SVG/STATCOM
■Electric Arc Furnaces – voltage stabilisation reduces tap-to-tap time and electrode consumption.
■Rolling Mills – elimination of voltage and harmonic distortions reduces reactive power demand and increases electrical system capacity.
■Mining and heavy industry – dynamic reactive power compensation stabilise the power system, especially on large motor start up, ensuring reliability of the power system.
■Wind and solar farms – meeting strict grid connection criteria by providing dynamic voltage control and voltage stability at the common coupling point (PCC).
■Renewables markets – including solar farms, wind farms, solar panel installations.
