Medium voltage Static Var Generator(STATCOM) is a voltage regulating device. It is based on a power electronics voltage source converter (VSC) and can act as either a source or sink of reactive AC power. It is a member of the flexible AC transmission systems (FACTS) family which detects and instantly compensates for voltage fluctuations or flicker, as well as controls power factor.

STATCOM(Medium Voltage Static Var Generator) gives customers the ability to solve power quality issues, maximize productivity and increase profitability.
STATCOM is a voltage regulating device. It is based on a power electronics voltage source converter (VSC) and can act as either a source or sink of reactive AC power. It is a member of the flexible AC transmission systems (FACTS) family which detects and instantly compensates for voltage fluctuations or flicker, as well as controls power factor.
As a fully controllable power electronic device, the STATCOM is capable of providing dynamically both capacitive and inductive VArs.
Compared to a SVC (static VAr compensator), a STATCOM has faster response time and better reactive power capability. STATCOM delivers maximum output current even at low system voltages, reducing the need for harmonic filter.

STATCOM Main Features
STATCOM product with high performance, high reliability is designed to meet users’ demands of improving power factor of power transmission, compensating harmonic and the negative sequence of current. It is easy to operate. Its features are as follows,
■Better control for power grids, better load compensation, better power factor improvement
SSC/STATCOM increase system stability and power quality by providing voltage control and support, reactive power control, power oscillation damping, and increased power transfer capacity. SSC/STATCOM enables electro-intensive industrial processes to obtain a grid connection by controlling flicker level, harmonic voltage distortion, and voltage unbalance. SSC/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
The SSC/STATCOM is geared to quickly inject significant inductive or capacitive power. Thus the SSC/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 SSC/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 SSC/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.

STATCOM Typical Application fileds
■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.
