Advance Static Var Generator / Statcom Var Generator

Static var generator/SVG/STATCOM is the new standard in reactive energy compensation. This power electronic current source is the accurate and highly reliable solution for today’s networks characterized by significant increase in harmonics, voltage variations caused by intermittent renewable sources connected to the network and voltage level due to the smart grid development. The DSP controlled IGBT topology enables a perfect compensation on each phase for both inductive and capacitive loads. It also correct phase unbalance where necessary. Immune to harmonics, resonance and voltage level, it offers a maintenance free solution reusable in any network configuration.

SVG Operating Principle

SVG checks the current through the external CT and performs computing through the external DSP to analysis the reactive content of the load current. After that , it controls the PWM signal generator based on the settings to send control signals to the internal IGBT. In the way, it generates reactive compensation current to implement dynamic reactive power compensation.

Multifunctional: Reactive power and imbalance compensation
Excellent reactive compensation: High speed, Precise (-0.99≤Cosφ≤0.99), Step-less, Bi-directional (capacitive and inductance) compensation
Excellent imbalance correction: Both negative and zero sequence, mitigates neutral current
Wide input voltage & frequency range Adapts to tough electrical environment
Low thermal loss (≤3% of rated SVG capacity), efficiency ≥ 97%
High stability: Infinite impedance to grid, avoids harmonic resonance problem
Flexible application: Modular design, embedded in standard or customized cabinet
Easy installation and maintenance: Easy installation for SVG module replacement and expansion
Wide capacity range: 50kvar~600kvar for a single cabinet, up to 10 cabinets in parallel
Environmental adaptability: -10~50°C temperature, compatible with diesel generators
Complete protection: Grid over/under voltage, SVG over current, over temperature, and others. All faults recorded in event log, convenient for failure analysis

SVG Application Field

Electric Arc Furnaces – voltage stabilization 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 stabilize 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.
